+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations
+below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it
+becomes a de-facto standard.  To achieve this, non-free programs must
+be allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control
+compilation and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at least
+    three years, to give the same user the materials specified in
+    Subsection 6a, above, for a charge no more than the cost of
+    performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply, and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License
+may add an explicit geographical distribution limitation excluding those
+countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms
+of the ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.
+It is safest to attach them to the start of each source file to most
+effectively convey the exclusion of warranty; and each file should
+have at least the "copyright" line and a pointer to where the full
+notice is found.
+
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or
+your school, if any, to sign a "copyright disclaimer" for the library,
+if necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James
+  Random Hacker.

+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004 Free

+
+Installation from Cloned Git Repository
+=======================================
+
+If you obtained the package by cloning the git repository, there are some
+additional steps required to build the package, as the generated 'configure'
+script and other supporting build files are not included in the repository.
+
+You must have the GNU autotools installed:
+
+- autoconf (version 2.69 or newer recommended)
+- automake (version 1.15 or newer recommended)
+- libtool (version 2.4.6 or newer recommended)
+
+If you plan to modify the source code, you may also need the following:
+
+- GNU Bison (verison 3.0.4 or newer required)
+- flex (version 2.6.4 or newer required)
+
+Generate the 'configure' script and other necessary build files by running
+'autoreconf' in the toplevel libconfig directory.
+
+Then, follow the basic installation instructions below.
+
+Basic Installation
+==================
+
+These are generic installation instructions when building from a released
+distribution tarball.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  (Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.)
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You only need
+`configure.ac' if you want to change it or regenerate `configure' using
+a newer version of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes awhile.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about.  Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c89 CFLAGS=-O2 LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you must use a version of `make' that
+supports the `VPATH' variable, such as GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   If you have to use a `make' that does not support the `VPATH'
+variable, you have to compile the package for one architecture at a
+time in the source code directory.  After you have installed the
+package for one architecture, use `make distclean' before reconfiguring
+for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' will install the package's files in
+`/usr/local/bin', `/usr/local/man', etc.  You can specify an
+installation prefix other than `/usr/local' by giving `configure' the
+option `--prefix=PREFIX'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PREFIX', the package will
+use PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the `--target=TYPE' option to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+will cause the specified gcc to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+     Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+(This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.)
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of the
+ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.  It is
+safest to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least the
+"copyright" line and a pointer to where the full notice is found.
+
+    {description}
+    Copyright (C) {year} {fullname}
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301
+    USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the library, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+  library `Frob' (a library for tweaking knobs) written by James Random
+  Hacker.
+
+  {signature of Ty Coon}, 1 April 1990
+  Ty Coon, President of Vice
+
+That's all there is to it!

+TO-DOs:
+
+These are features that have been requested, and have been considered,
+but are not yet implemented, because I'm undecided about how or whether they
+should be implemented, and/or because they are difficult and/or time-consuming
+to implement.
+
+Also, some of these features tend to push libconfig toward becoming a
+general-purpose structured-data storage mechanism, which is really not the
+intended purpose of this library. I think something like sqlite is better
+suited for that sort of thing.
+
+
+* Add support for copying settings from one configuration to another. Need a
+  recursive function to copy a setting and call itself on all child settings.
+
+
+* Add a += operator, so that additional elements can be appended to a list or
+  array. The issue with this is defining a consistent syntax. For example:
+
+  x = ( 1, 2, 3 );
+  x += ( 4, 5 );
+
+  Should this result in ( 1, 2, 3, 4, 5 ), or ( 1, 2, 3, ( 4, 5 ))? I believe
+  it should be the latter. However, only the former makes sense for arrays.

+* Add the ability to insert/delete elements at any position in a list or
+  array. A simple implementation would be expensive (shift all the elements
+  by one for every insert/delete), and a more efficient implementation would
+  add a lot of complexity to the library.
+
+
+* Add limited support for preserving comments.
+
+
+* Add support for unicode strings? A bit problematic, since flex doesn't
+  support unicode input, AFAICT. But maybe supply convenience functions to
+  convert between parsed UTF-8 strings and std::wstring.

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH

+% Please try the latest version of texinfo.tex before submitting bug

+%   http://ftpmirror.gnu.org/texinfo/ (same, via a mirror), or

+%
+% To process a Texinfo manual with TeX, it's most reliable to use the
+% texi2dvi shell script that comes with the distribution.  For a simple
+% manual foo.texi, however, you can get away with this:
+%   tex foo.texi
+%   texindex foo.??
+%   tex foo.texi
+%   tex foo.texi
+%   dvips foo.dvi -o  # or whatever; this makes foo.ps.
+% The extra TeX runs get the cross-reference information correct.
+% Sometimes one run after texindex suffices, and sometimes you need more
+% than two; texi2dvi does it as many times as necessary.
+%
+% It is possible to adapt texinfo.tex for other languages, to some
+% extent.  You can get the existing language-specific files from the
+% full Texinfo distribution.

+% PDF uses PostScript string constants for the names of xref targets,

+% @multitable macros
+% Amy Hendrickson, 8/18/94, 3/6/96
+%
+% @multitable ... @end multitable will make as many columns as desired.
+% Contents of each column will wrap at width given in preamble.  Width
+% can be specified either with sample text given in a template line,
+% or in percent of \hsize, the current width of text on page.
+
+% Table can continue over pages but will only break between lines.
+
+% To make preamble:
+%
+% Either define widths of columns in terms of percent of \hsize:
+%   @multitable @columnfractions .25 .3 .45
+%   @item ...
+%
+%   Numbers following @columnfractions are the percent of the total
+%   current hsize to be used for each column. You may use as many
+%   columns as desired.
+
+
+% Or use a template:
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item ...
+%   using the widest term desired in each column.
+
+% Each new table line starts with @item, each subsequent new column
+% starts with @tab. Empty columns may be produced by supplying @tab's
+% with nothing between them for as many times as empty columns are needed,
+% ie, @tab@tab@tab will produce two empty columns.
+
+% @item, @tab do not need to be on their own lines, but it will not hurt
+% if they are.
+
+% Sample multitable:
+
+%   @multitable {Column 1 template} {Column 2 template} {Column 3 template}
+%   @item first col stuff @tab second col stuff @tab third col
+%   @item
+%   first col stuff
+%   @tab
+%   second col stuff
+%   @tab
+%   third col
+%   @item first col stuff @tab second col stuff
+%   @tab Many paragraphs of text may be used in any column.
+%
+%         They will wrap at the width determined by the template.
+%   @item@tab@tab This will be in third column.
+%   @end multitable
+
+% Default dimensions may be reset by user.
+% @multitableparskip is vertical space between paragraphs in table.
+% @multitableparindent is paragraph indent in table.
+% @multitablecolmargin is horizontal space to be left between columns.
+% @multitablelinespace is space to leave between table items, baseline
+%                                                            to baseline.

+# Method Chained libconfig #
+
+**Exception free + header only + method chained + config files**
+
+Provides reading the configuration and defining the configuration specification at once.
+
+### Features ###
+
+ * default values
+ * limits (min/max)
+ * mandatory/optional values
+ * help text output for expected config format on specification violation
+ * capturing and outputting expected configuration specification/defaults
+
+While it is possible to write a config file with this extension using the configuration specification capturing feature, it is not intended to be used as a full fledged config writer.
+
+### Example ###
+
+```C++
+#include <libconfig_chained.h>
+
+using namespace std;
+using namespace libconfig;
+
+int main(int argc, char **argv)
+{
+    Config cfg;
+    cfg.readFile("example.cfg");
+    ChainedSetting cs(cfg.getRoot());
+
+    string name = cs["name"].defaultValue("<name>").isMandatory();
+    string abstract = cs["abstract"].defaultValue("<unknown>");
+    double longitude = cs["longitude"].min(-180.0).max(180.0).isMandatory();
+    double latitude = cs["latitude"].min(-90.0).max(90.0).isMandatory();
+
+    if (cs.isAnyMandatorySettingMissing())
+    {
+        cerr << "Cannot proceed until all mandatory settings are set." << endl;
+    }
+}
+```
+
+Console Output:
+```sh
+'longitude' setting is out of valid bounds (max: 180). Value was: 1200.35
+Missing 'latitude' setting in configuration file.
+Cannot proceed until all mandatory settings are set.
+```
+
+---
+
+### How to integrate into your project ###
+
+ 1. Link the libconfig++.[lib/la/a] library as usual (see standard use of libconfig++).
+ * Replace any includes of libconfig.h++ by libconfig_chained.h.
+ * Use method chained candy as displayed above.

+GNU GENERAL PUBLIC LICENSE
+                       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+                            NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    Simple program to use libconfig9 configuration files in bash scripts
+    Copyright (C) 2013  lucas-net-pl
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License along
+    with this program; if not, write to the Free Software Foundation, Inc.,
+    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  {signature of Ty Coon}, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+Instalation:
+------------
+
+First of all, You must place ls-config binary and lslib-core bash
+script in the same directory (default: /usr/share/ls/lib)
+
+Next in lslib-core header chcange configuration:
+PACD tu point to parent directory of paced files
+then LIBD must point relative (tu PACD) to directory 
+whrere script placed
+
+Usage:
+------
+
+In You bash script, first of all define LS_EXEC variable,
+and set his value to 1. (It protect lslib-core) to run
+standalone
+
+Next, source library:
+source /usr/share/ls/lib/lslib-core
+
+After thet You can use following function:
+
+Functions:
+----------
+
+cfg_g $PATH               - this echo variable value of given PATH 
+                            and return error code
+cfg_t $PATH               - this echo variable type of given PATH 
+                            and return error code
+cfg_c $PATH               - this echo cout of variable elements 
+                            and return error code
+cfg_s $PATH $DATA [$TYPE] - this set variable of given PATH or create new
+                            variable valuse are set to DATA, and if this
+                            create new variable, variable will be type TYPE
+cfg_u $PATH               - this unset (remove) variable of given PATH
+                            and return error code
+cfg_f_g $FILE $PATH       - same as cfg_g, but operate on given FILE
+cfg_f_t $FILE $PATH       - same as cfg_t, but operate on given FILE
+cfg_f_c $FILE $PATH       - same as cfg_c, but operate on given FILE
+cfg_f_s $FILE $PATH $DATA [$TYPE] - same as cfg_s, but operate on given FILE
+cfg_f_u $FILE $PATH       - same as cfg_u, but operate on given FILE
+
+Configuration files:
+--------------------
+
+By default configuration file are placed in /etc/ls/
+with the same name as script file name
+(used in cfg_g, cfg_t, cfg_c, cfg_s, cfg_u)
+
+But if You need, You can use any location of configuration file
+by using cfg_f_* functions, giving configuration file location as
+first argument
+
+Detailed configuration file shema are publicated on:
+http://www.hyperrealm.com/libconfig/
+And his gramar on:
+http://www.hyperrealm.com/libconfig/libconfig_manual.html#Configuration-Files
+
+there are only short describe:

+Instalation:
+------------
+
+First place somewhere ls-config binary, or make it from source
+
+Then if You woud like use it with national translation, then You muas build
+it form source and then copy *.mo files according to You system
+
+Usage:
+------
+
+Remember to call ls-config always with -f parameter,
+wich give ls-config inormation wich config file use.
+
+Then this program operate in three based modes:
+-g (get) for reading values (default)
+-s (set) for store values
+-h (help) for display help message
+both parameter (-g and -s) nedd to give it variable path
+(internal configuration variable path)
+
+for exapmle read info value from config file:
+ls-config -f config -g info
+
+Then You can set this value to another
+ls-config -f config -s info -d "Somethint to write"
+
+But when You wand to addn new configutation variable you must
+specify his type:
+ls-config -f config -s someint -d 10 -p int
+
+You can remove (unset) variable too. This is subfunstion of setting:
+ls-config -f config -s someint -u
+
+When reading You cent use following flag:
+-v - read only variable valut
+-t - read only variable type
+-c - read only variable element count (sense only in types: array, list, group)
+-i - read only variable index (sense only in type: array, list) 
+-n - read only variable name
+
+and sometimes usable 
+-q  - to wori in quiet mode usable in scripts.
+
+For example to read variable somevar type, where variable in group foo:
+ls-config -f config -g "foo.somevar" -t
+
+For detailed list of parametera (long options available too) run ls-config
+in help mode:
+ls-config -h

+@center Version 2.1, February 1999
+
+@sp 1
+
+Copyright @copyright{} 1991, 1999 Free Software Foundation, Inc.,
+59 Temple Place, Suite 330, Boston, MA  02111-1307  USA 
+
+Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+as the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+
+@sp 1
+@center Preamble
+@sp 1
+
+The licenses for most software are designed to take away your freedom to
+share and change it.  By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software--to
+make sure the software is free for all its users.
+
+This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the Free
+Software Foundation and other authors who decide to use it.  You can use
+it too, but we suggest you first think carefully about whether this
+license or the ordinary General Public License is the better strategy to
+use in any particular case, based on the explanations below.
+
+When we speak of free software, we are referring to freedom of use, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish); that you receive source code or can get it if
+you want it; that you can change the software and use pieces of it in
+new free programs; and that you are informed that you can do these
+things.
+
+To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+For example, if you distribute copies of the library, whether gratis or
+for a fee, you must give the recipients all the rights that we gave you.
+You must make sure that they, too, receive or can get the source code.
+If you link other code with the library, you must provide complete
+object files to the recipients, so that they can relink them with the
+library after making changes to the library and recompiling it.  And you
+must show them these terms so they know their rights.
+
+We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+To protect each distributor, we want to make it very clear that there is
+no warranty for the free library.  Also, if the library is modified by
+someone else and passed on, the recipients should know that what they
+have is not the original version, so that the original author's
+reputation will not be affected by problems that might be introduced by
+others.
+
+Finally, software patents pose a constant threat to the existence of any
+free program.  We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder.  Therefore, we insist that any patent license
+obtained for a version of the library must be consistent with the full
+freedom of use specified in this license.
+
+Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License.  This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License.  We use this license for
+certain libraries in order to permit linking those libraries into
+non-free programs.
+
+When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the entire
+combination fits its criteria of freedom.  The Lesser General Public
+License permits more lax criteria for linking other code with the
+library.
+
+We call this license the ``Lesser'' General Public License because it does
+Less to protect the user's freedom than the ordinary General Public
+License.  It also provides other free software developers Less of an
+advantage over competing non-free programs.  These disadvantages are the
+reason we use the ordinary General Public License for many libraries.
+However, the Lesser license provides advantages in certain special
+circumstances.
+
+For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a
+de-facto standard.  To achieve this, non-free programs must be allowed
+to use the library.  A more frequent case is that a free library does
+the same job as widely used non-free libraries.  In this case, there is
+little to gain by limiting the free library to free software only, so we
+use the Lesser General Public License.
+
+In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of free
+software.  For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system,
+as well as its variant, the GNU/Linux operating system.
+
+Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is linked
+with the Library has the freedom and the wherewithal to run that program
+using a modified version of the Library.
+
+The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+``work based on the library'' and a ``work that uses the library''.  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+@page
+
+@center GNU LESSER GENERAL PUBLIC LICENSE
+@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+@enumerate 0
+
+@sp 1
+@item
+This License Agreement applies to any software library or other program
+which contains a notice placed by the copyright holder or other
+authorized party saying it may be distributed under the terms of this
+Lesser General Public License (also called ``this License'').  Each
+licensee is addressed as ``you''.
+
+A ``library'' means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+The ``Library'', below, refers to any such software library or work which
+has been distributed under these terms.  A ``work based on the Library''
+means either the Library or any derivative work under copyright law:
+that is to say, a work containing the Library or a portion of it, either
+verbatim or with modifications and/or translated straightforwardly into
+another language.  (Hereinafter, translation is included without
+limitation in the term ``modification''.)
+
+``Source code'' for a work means the preferred form of the work for making
+modifications to it.  For a library, complete source code means all the
+source code for all modules it contains, plus any associated interface
+definition files, plus the scripts used to control compilation and
+installation of the library.
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of running
+a program using the Library is not restricted, and output from such a
+program is covered only if its contents constitute a work based on the
+Library (independent of the use of the Library in a tool for writing
+it).  Whether that is true depends on what the Library does and what the
+program that uses the Library does.
+
+@sp 1
+@item
+You may copy and distribute verbatim copies of the Library's complete
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the notices
+that refer to this License and to the absence of any warranty; and
+distribute a copy of this License along with the Library.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+@sp 1
+@item
+You may modify your copy or copies of the Library or any portion of it,
+thus forming a work based on the Library, and copy and distribute such
+modifications or work under the terms of Section 1 above, provided that
+you also meet all of these conditions:
+
+@enumerate a
+
+@item
+The modified work must itself be a software library.
+
+@sp 1
+@item
+You must cause the files modified to carry prominent notices stating
+that you changed the files and the date of any change.
+
+@sp 1
+@item
+You must cause the whole of the work to be licensed at no charge to all
+third parties under the terms of this License.
+
+@sp 1
+@item
+If a facility in the modified Library refers to a function or a table of
+data to be supplied by an application program that uses the facility,
+other than as an argument passed when the facility is invoked, then you
+must make a good faith effort to ensure that, in the event an
+application does not supply such function or table, the facility still
+operates, and performs whatever part of its purpose remains meaningful.
+
+(For example, a function in a library to compute square roots has a
+purpose that is entirely well-defined independent of the application.
+Therefore, Subsection 2d requires that any application-supplied function
+or table used by this function must be optional: if the application does
+not supply it, the square root function must still compute square
+roots.)
+
+@end enumerate
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library, and
+can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based on
+the Library, the distribution of the whole must be on the terms of this
+License, whose permissions for other licensees extend to the entire
+whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of a
+storage or distribution medium does not bring the other work under the
+scope of this License.
+
+@sp 1
+@item
+You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so that
+they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+Once this change is made in a given copy, it is irreversible for that
+copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+This option is useful when you wish to copy part of the code of the
+Library into a program that is not a library.
+
+@sp 1
+@item
+You may copy and distribute the Library (or a portion or derivative of
+it, under Section 2) in object code or executable form under the terms
+of Sections 1 and 2 above provided that you accompany it with the
+complete corresponding machine-readable source code, which must be
+distributed under the terms of Sections 1 and 2 above on a medium
+customarily used for software interchange.
+
+If distribution of object code is made by offering access to copy from a
+designated place, then offering equivalent access to copy the source
+code from the same place satisfies the requirement to distribute the
+source code, even though third parties are not compelled to copy the
+source along with the object code.
+
+@sp 1
+@item
+A program that contains no derivative of any portion of the Library, but
+is designed to work with the Library by being compiled or linked with
+it, is called a ``work that uses the Library''.  Such a work, in
+isolation, is not a derivative work of the Library, and therefore falls
+outside the scope of this License.
+
+However, linking a ``work that uses the Library'' with the Library creates
+an executable that is a derivative of the Library (because it contains
+portions of the Library), rather than a ``work that uses the library''.
+The executable is therefore covered by this License.  Section 6 states
+terms for distribution of such executables.
+
+When a ``work that uses the Library'' uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be linked
+without the Library, or if the work is itself a library.  The threshold
+for this to be true is not precisely defined by law.
+
+If such an object file uses only numerical parameters, data structure
+layouts and accessors, and small macros and small inline functions (ten
+lines or less in length), then the use of the object file is
+unrestricted, regardless of whether it is legally a derivative work.
+(Executables containing this object code plus portions of the Library
+will still fall under Section 6.)
+
+Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6, whether
+or not they are linked directly with the Library itself.
+
+@sp 1
+@item
+As an exception to the Sections above, you may also combine or link a
+``work that uses the Library'' with the Library to produce a work
+containing portions of the Library, and distribute that work under terms
+of your choice, provided that the terms permit modification of the work
+for the customer's own use and reverse engineering for debugging such
+modifications.
+
+You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+@enumerate a
+
+@sp 1
+@item
+Accompany the work with the complete corresponding machine-readable
+source code for the Library including whatever changes were used in the
+work (which must be distributed under Sections 1 and 2 above); and, if
+the work is an executable linked with the Library, with the complete
+machine-readable ``work that uses the Library'', as object code and/or
+source code, so that the user can modify the Library and then relink to
+produce a modified executable containing the modified Library.  (It is
+understood that the user who changes the contents of definitions files
+in the Library will not necessarily be able to recompile the application
+to use the modified definitions.)
+
+@sp 1
+@item
+Use a suitable shared library mechanism for linking with the Library.  A
+suitable mechanism is one that (1) uses at run time a copy of the
+library already present on the user's computer system, rather than
+copying library functions into the executable, and (2) will operate
+properly with a modified version of the library, if the user installs
+one, as long as the modified version is interface-compatible with the
+version that the work was made with.
+
+@sp 1
+@item
+Accompany the work with a written offer, valid for at least three years,
+to give the same user the materials specified in Subsection 6a, above,
+for a charge no more than the cost of performing this distribution.
+
+@sp 1
+@item
+If distribution of the work is made by offering access to copy from a
+designated place, offer equivalent access to copy the above specified
+materials from the same place.
+
+@sp 1
+@item
+Verify that the user has already received a copy of these materials or
+that you have already sent this user a copy.
+
+@end enumerate
+
+For an executable, the required form of the ``work that uses the Library''
+must include any data and utility programs needed for reproducing the
+executable from it.  However, as a special exception, the materials to
+be distributed need not include anything that is normally distributed
+(in either source or binary form) with the major components (compiler,
+kernel, and so on) of the operating system on which the executable runs,
+unless that component itself accompanies the executable.
+
+It may happen that this requirement contradicts the license restrictions
+of other proprietary libraries that do not normally accompany the
+operating system.  Such a contradiction means you cannot use both them
+and the Library together in an executable that you distribute.
+
+@sp 1
+@item
+You may place library facilities that are a work based on the Library
+side-by-side in a single library together with other library facilities
+not covered by this License, and distribute such a combined library,
+provided that the separate distribution of the work based on the Library
+and of the other library facilities is otherwise permitted, and provided
+that you do these two things:
+
+@enumerate a
+
+@sp 1
+@item
+Accompany the combined library with a copy of the same work based on the
+Library, uncombined with any other library facilities.  This must be
+distributed under the terms of the Sections above.
+
+@sp 1
+@item
+Give prominent notice with the combined library of the fact that part of
+it is a work based on the Library, and explaining where to find the
+accompanying uncombined form of the same work.
+
+@end enumerate
+
+@sp 1
+@item
+You may not copy, modify, sublicense, link with, or distribute the
+Library except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, link with, or distribute the
+Library is void, and will automatically terminate your rights under this
+License.  However, parties who have received copies, or rights, from you
+under this License will not have their licenses terminated so long as
+such parties remain in full compliance.
+
+@sp 1
+@item
+You are not required to accept this License, since you have not signed
+it.  However, nothing else grants you permission to modify or distribute
+the Library or its derivative works.  These actions are prohibited by
+law if you do not accept this License.  Therefore, by modifying or
+distributing the Library (or any work based on the Library), you
+indicate your acceptance of this License to do so, and all its terms and
+conditions for copying, distributing or modifying the Library or works
+based on it.
+
+@sp 1
+@item
+Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+@sp 1
+@item
+If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent license
+would not permit royalty-free redistribution of the Library by all those
+who receive copies directly or indirectly through you, then the only way
+you could satisfy both it and this License would be to refrain entirely
+from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply, and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is implemented
+by public license practices.  Many people have made generous
+contributions to the wide range of software distributed through that
+system in reliance on consistent application of that system; it is up to
+the author/donor to decide if he or she is willing to distribute
+software through any other system and a licensee cannot impose that
+choice.
+
+This section is intended to make thoroughly clear what is believed to be
+a consequence of the rest of this License.
+
+@sp 1
+@item
+If the distribution and/or use of the Library is restricted in certain
+countries either by patents or by copyrighted interfaces, the original
+copyright holder who places the Library under this License may add an
+explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.

+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and ``any

+@center How to Apply These Terms to Your New Libraries
+
+If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of
+the ordinary General Public License).
+
+To apply these terms, attach the following notices to the library.  It
+is safest to attach them to the start of each source file to most
+effectively convey the exclusion of warranty; and each file should have
+at least the ``copyright'' line and a pointer to where the full notice is
+found.

+
+@i{Libconfig} is a library for reading, manipulating, and writing
+structured configuration files. The library features a fully
+reentrant parser and includes bindings for both the C and C++
+programming languages.
+
+The library runs on modern POSIX-compilant systems, such as Linux,
+Solaris, and Mac OS X (Darwin), as well as on Microsoft Windows
+2000/XP and later (with either Microsoft Visual Studio 2005 or later,
+or the GNU toolchain via the MinGW environment).

+@section Why Another Configuration File Library?
+
+There are several open-source configuration file libraries available
+as of this writing. This library was written because each of those
+libraries falls short in one or more ways. The main features of
+@i{libconfig} that set it apart from the other libraries are:
+
+@itemize @bullet
+
+@item A fully reentrant parser. Independent configurations can be parsed in concurrent threads at the same time.
+
+@item Both C @i{and} C++ bindings, as well as hooks to allow for the creation of wrappers in other languages.
+
+@item A simple, structured configuration file format that is more
+readable and compact than XML and more flexible than the obsolete but
+prevalent Windows ``INI'' file format.
+
+@item A low-footprint implementation (just 37K for the C library and 76K for
+the C++ library) that is suitable for memory-constrained systems.
+
+@item Proper documentation.

+@comment  node-name,  next,  previous,  up
+@section Multithreading Issues
+
+@i{Libconfig} is fully @dfn{reentrant}; the functions in the library
+do not make use of global variables and do not maintain state between
+successive calls. Therefore two independent configurations may be safely
+manipulated concurrently by two distinct threads.
+
+@i{Libconfig} is not @dfn{thread-safe}. The library is not aware of
+the presence of threads and knows nothing about the host system's
+threading model. Therefore, if an instance of a configuration is to be
+accessed from multiple threads, it must be suitably protected by
+synchronization mechanisms like read-write locks or mutexes; the
+standard rules for safe multithreaded access to shared data must be
+observed.
+
+@i{Libconfig} is not @dfn{async-safe}. Calls should not be made into
+the library from signal handlers, because some of the C library
+routines that it uses may not be async-safe.
+
+@i{Libconfig} is not guaranteed to be @dfn{cancel-safe}. Since it is
+not aware of the host system's threading model, the library does not
+contain any thread cancellation points. In most cases this will not be
+an issue for multithreaded programs. However, be aware that some of
+the routines in the library (namely those that read/write
+configurations from/to files or streams) perform I/O using C library
+routines which may potentially block; whether or not these C library
+routines are cancel-safe depends on the host system.

+@section Internationalization Issues
+
+@cindex Unicode
+@cindex UTF-8
+@i{Libconfig} does not natively support Unicode configuration files,
+but string values may contain Unicode text encoded in UTF-8; such
+strings will be treated as ordinary 8-bit ASCII text by the
+library. It is the responsibility of the calling program to perform
+the necessary conversions to/from wide (@t{wchar_t}) strings using the
+wide string conversion functions such as @t{mbsrtowcs()} and
+@t{wcsrtombs()} or the @t{iconv()} function of the @i{libiconv}
+library.
+
+@cindex locale
+The textual representation of a floating point value varies by
+locale. However, the @i{libconfig} grammar specifies that
+floating point values are represented using a period (`.') as the
+radix symbol; this is consistent with the grammar of most programming
+languages. When a configuration is read in or written out,
+@i{libconfig} temporarily changes the @t{LC_NUMERIC} category of the
+locale of the calling thread to the ``C'' locale to ensure consistent
+handling of floating point values regardless of the locale(s) in use
+by the calling program.
+
+Note that the MinGW environment does not (as of this writing) provide
+functions for changing the locale of the calling thread. Therefore,
+when using @i{libconfig} in that environment, the calling program is
+responsible for changing the @t{LC_NUMERIC} category of the locale to
+the "C" locale before reading or writing a configuration.
+
+@node Compiling Using pkg-config, Version Test Macros, Internationalization Issues, Introduction
+@comment  node-name,  next,  previous,  up
+@section Compiling Using pkg-config
+
+@cindex pkg-config
+On UNIX systems you can use the @i{pkg-config} utility (version 0.20
+or later) to automatically select the appropriate compiler and linker
+switches for @i{libconfig}. Ensure that the environment variable
+@code{PKG_CONFIG_PATH} contains the absolute path to the
+@file{lib/pkgconfig} subdirectory of the @i{libconfig} installation. Then,
+you can compile and link C programs with @i{libconfig} as follows:
+
+@smallexample
+gcc `pkg-config --cflags libconfig` myprogram.c -o myprogram \
+    `pkg-config --libs libconfig`
+@end smallexample
+@sp 1
+
+And similarly, for C++ programs:
+
+@smallexample
+g++ `pkg-config --cflags libconfig++` myprogram.cpp -o myprogram \
+    `pkg-config --libs libconfig++`
+@end smallexample
+
+@sp 1
+Note the backticks in the above examples.
+
+When using @b{autoconf}, the @code{PKG_CHECK_MODULES} m4 macro may be used to check for the presence of a given version of @i{libconfig}, and set the appropriate Makefile variables automatically. For example:
+
+@smallexample
+PKG_CHECK_MODULES([LIBCONFIGXX], [libconfig++ >= 1.4],,
+  AC_MSG_ERROR([libconfig++ 1.4 or newer not found.])
+)
+@end smallexample
+
+In the above example, if @i{libconfig++} version 1.4 or newer is found,
+the Makefile variables @code{LIBCONFIGXX_LIBS} and @code{LIBCONFIGXX_CFLAGS} will be
+set to the appropriate compiler and linker flags for compiling with
+@i{libconfig}, and if it is not found, the configure script will abort
+with an error to that effect.
+
+@node Version Test Macros, , Compiling Using pkg-config, Introduction
+@comment  node-name,  next,  previous,  up
+@section Version Test Macros
+
+The @file{libconfig.h} header declares the following macros:
+
+@defmac LIBCONFIG_VER_MAJOR
+@defmacx LIBCONFIG_VER_MINOR
+@defmacx LIBCONFIG_VER_REVISION
+
+These macros represent the major version, minor version, and revision
+of the @i{libconfig} library. For example, in @i{libconfig} 1.4 these
+are defined as @samp{1}, @samp{4}, and @samp{0}, respectively. These
+macros can be used in preprocessor directives to determine which
+@i{libconfig} features and/or APIs are present. For example:
+
+@smallexample
+#if (((LIBCONFIG_VER_MAJOR == 1) && (LIBCONFIG_VER_MINOR >= 4)) \
+     || (LIBCONFIG_VER_MAJOR > 1))
+  /* use features present in libconfig 1.4 and later */
+#endif
+@end smallexample
+
+These macros were introduced in @i{libconfig} 1.4.
+
+@end defmac
+
+Similarly, the @file{libconfig.h++} header declares the following macros:
+
+@defmac LIBCONFIGXX_VER_MAJOR
+@defmacx LIBCONFIGXX_VER_MINOR
+@defmacx LIBCONFIGXX_VER_REVISION
+
+These macros represent the major version, minor version, and revision

+
+@cindex path
+Settings can be uniquely identified within the configuration by a
+@dfn{path}. The path is a dot-separated sequence of names, beginning
+at a top-level group and ending at the setting itself. Each name in
+the path is the name of a setting; if the setting has no name because
+it is an element in a list or array, an integer index in square
+brackets can be used as the name.
+
+For example, in our hypothetical configuration file, the path to the
+@code{x} setting is @code{application.window.pos.x}; the path to the
+@code{version} setting is simply @code{version}; and the path to the
+@code{title} setting of the second book in the @code{books} list is
+@code{application.books.[1].title}.
+
+The datatype of a value is determined from the format of the value
+itself. If the value is enclosed in double quotes, it is treated as a
+string. If it looks like an integer or floating point number, it is
+treated as such. If it is one of the values @code{TRUE}, @code{true},
+@code{FALSE}, or @code{false} (or any other mixed-case version of
+those tokens, e.g., @code{True} or @code{FaLsE}), it is treated as a
+boolean. If it consists of a comma-separated list of values enclosed
+in square brackets, it is treated as an array. And if it consists of a
+comma-separated list of values enclosed in parentheses, it is treated
+as a list. Any value which does not meet any of these criteria is
+considered invalid and results in a parse error.
+
+All names are case-sensitive. They may consist only of alphanumeric
+characters, dashes (@samp{-}), underscores (@samp{_}), and asterisks
+(@samp{*}), and must begin with a letter or asterisk. No other
+characters are allowed.
+
+In C and C++, integer, 64-bit integer, floating point, and string
+values are mapped to the native types @code{int}, @code{long long},
+@code{double}, and @code{const char *}, respectively. The boolean type
+is mapped to @code{int} in C and @code{bool} in C++.
+
+The following sections describe the elements of the configuration file
+grammar in additional detail.
+
+@node Settings, Groups, , Configuration Files

+@section Settings
+
+A setting has the form:
+
+@i{name} @b{=} @i{value} @b{;}
+
+or:
+
+@i{name} @b{:} @i{value} @b{;}
+
+The trailing semicolon is optional. Whitespace is not significant.

+
+An array has the form:

+
+An array may have zero or more elements, but the elements must all be
+scalar values of the same type.
+
+The last element in an array may be followed by a comma, which will be ignored.
+

+@comment  node-name,  next,  previous,  up
+@section Lists
+
+A list has the form:

+@b{(} @i{value}@b{,} @i{value ...} @b{)}
+
+A list may have zero or more elements, each of which can be a scalar
+value, an array, a group, or another list.
+
+The last element in a list may be followed by a comma, which will be ignored.
+
+@node Integer Values, 64-bit Integer Values, Lists, Configuration Files
+@comment  node-name,  next,  previous,  up
+@section Integer Values
+
+Integers can be represented in one of two ways: as a series of one or
+more decimal digits (@samp{0} - @samp{9}), with an optional leading
+sign character (@samp{+} or @samp{-}); or as a hexadecimal value
+consisting of the characters @samp{0x} followed by a series of one or
+more hexadecimal digits (@samp{0} - @samp{9}, @samp{A} - @samp{F},
+@samp{a} - @samp{f}). Additionally, octal notation integers (that is,
+those having a leading zero with non-zero value) are also allowed.
+
+@node 64-bit Integer Values, Floating Point Values, Integer Values, Configuration Files
+@comment  node-name,  next,  previous,  up
+@section 64-bit Integer Values
+
+Long long (64-bit) integers are represented identically to integers,
+except that an `L' character is appended to indicate a 64-bit
+value. For example, @samp{0L} indicates a 64-bit integer value 0.  As
+of version 1.5 of the library, the trailing `L' is optional; if the
+integer value exceeds the range of a 32-bit integer, it will
+automatically be interpreted as a 64-bit integer.
+
+The @i{integer} and @i{64-bit integer} setting types are interchangeable to the
+extent that a conversion between the corresponding native types would not
+result in an overflow or underflow. For example, a @i{long long} value can be
+written to a setting that has an @i{integer} type, if that value is within the
+range of an @i{int}. This rule applies to every API function or method that
+reads a value from or writes a value to a setting: if the type conversion would
+not result in an overflow or underflow, then the call will succeed, and
+otherwise it will fail. This behavior was not well-defined prior to version 1.7
+of the library.
+
+@node Floating Point Values, Boolean Values, 64-bit Integer Values, Configuration Files
+@comment  node-name,  next,  previous,  up
+@section Floating Point Values
+
+Floating point values consist of a series of one or more digits, one
+decimal point, an optional leading sign character (@samp{+} or
+@samp{-}), and an optional exponent. An exponent consists of the
+letter @samp{E} or @samp{e}, an optional sign character, and a series
+of one or more digits.
+
+@node Boolean Values, String Values, Floating Point Values, Configuration Files
+@comment  node-name,  next,  previous,  up

+
+Boolean values may have one of the following values: @samp{true},
+@samp{false}, or any mixed-case variation thereof.
+
+@node String Values, Comments, Boolean Values, Configuration Files
+@comment  node-name,  next,  previous,  up
+@section String Values
+
+@cindex escape sequence
+String values consist of arbitrary text delimited by double
+quotes. Literal double quotes can be escaped by preceding them with a
+backslash: @samp{\"}. The escape sequences @samp{\\}, @samp{\f},
+@samp{\n}, @samp{\r}, and @samp{\t} are also recognized, and have the
+usual meaning.
+
+In addition, the @samp{\x} escape sequence is supported; this sequence
+must be followed by @i{exactly two} hexadecimal digits, which represent an
+8-bit ASCII value. For example, @samp{\xFF} represents the character
+with ASCII code 0xFF.
+
+No other escape sequences are currently supported.
+
+Adjacent strings are automatically concatenated, as in C/C++ source
+code. This is useful for formatting very long strings as sequences of
+shorter strings. For example, the following constructs are equivalent:
+
+@itemize @bullet
+@item
+@code{"The quick brown fox jumped over the lazy dog."}
+
+@item
+@code{"The quick brown fox"} @*
+@code{" jumped over the lazy dog."}
+
+@item
+@code{"The quick" /* comment */ " brown fox " // another comment} @*
+@code{"jumped over the lazy dog."}
+
+@end itemize
+@page
+@node Comments, Include Directives, String Values, Configuration Files
+@comment  node-name,  next,  previous,  up
+@section Comments
+
+@cindex comment
+Three types of comments are allowed within a configuration:
+
+@itemize @bullet
+
+@item Script-style comments. All text beginning with a @samp{#} character
+to the end of the line is ignored.
+
+@item C-style comments. All text, including line breaks, between a starting
+@samp{/*} sequence and an ending @samp{*/} sequence is ignored.
+
+@item C++-style comments. All text beginning with a @samp{//} sequence to the
+end of the line is ignored.
+
+@end itemize
+
+As expected, comment delimiters appearing within quoted strings are
+treated as literal text.
+
+Comments are ignored when the configuration is read in, so they are
+not treated as part of the configuration. Therefore if the
+configuration is written back out to a stream, any comments that were
+present in the original configuration will be lost.
+
+
+@node Include Directives, , Comments, Configuration Files
+@comment  node-name,  next,  previous,  up
+@section Include Directives
+
+@cindex include directive
+A configuration file may ``include'' the contents of other files
+using an @i{include directive}. This directive has the effect of
+inlining the contents of the named file(s) at the point of inclusion.
+
+An include directive must appear on its own line in the input. It has
+the form:
+
+@b{@@include "}@i{path}@b{"}
+
+@cindex include function
+The interpretation of @i{path} depends on the currently registered
+@i{include function}. The default include function prepends the include
+directory, if any, to @i{path}, and then interprets the result as a single,
+literal file path. The application may supply its own include function which
+does variable substitution, wildcard expansion, or other transformations,
+returning a list of zero or more paths to files whose contents should be inlined
+at the point of inclusion.
+
+Any backslashes or double quotes in the path must be escaped as
+@samp{\\} and @samp{\"}, respectively.
+
+For example, consider the following two configuration files:
+
+@cartouche
+@smallexample
+# file: quote.cfg
+quote = "Criticism may not be agreeable, but it is necessary."
+        " It fulfils the same function as pain in the human"
+        " body. It calls attention to an unhealthy state of"
+        " things.\n"
+        "\t--Winston Churchill";
+@end smallexample
+@end cartouche
+
+@cartouche
+@smallexample
+# file: test.cfg
+info: @{
+  name = "Winston Churchill";
+  @@include "quote.cfg"
+  country = "UK";
+@};
+@end smallexample
+@end cartouche
+
+The resulting configuration will be equivalent to one in which the
+contents of the file @samp{quote.cfg} appeared at the point where the
+include directive is placed.
+
+Include files may be nested to a maximum of 10 levels; exceeding this
+limit results in a parse error.
+
+When the path argument to an @b{@@include} directive is a relative
+path, then it will be interpreted as being relative to the include
+directory that has been been set by means of
+@code{config_set_include_dir()}. If no include directory has been set,
+then it will be taken as being relative to the program's current
+working directory.
+
+Like comments, include directives are not part of the configuration
+file syntax. They are processed before the configuration itself is
+parsed. Therefore, they are not preserved when the configuration is
+written back out to a stream. There is presently no support for
+programmatically inserting include directives into a configuration.

+is reinstated.
+
+For example, if the include directory is set to @file{/usr/local/etc},
+the include directive @samp{@@include "configs/extra.cfg"} would include the
+file @file{/usr/local/etc/configs/extra.cfg}.

+
+@tindex config_include_fn_t
+The type @i{config_include_fn_t} is a type alias
+for a function whose signature is:
+
+@deftypefun @w{const char **} func (@w{config_t *@var{config}}, @w{const char *@var{include_dir}}, @w{const char *@var{path}}, @w{const char **@var{error}})
+
+The function receives the configuration @var{config}, the
+configuration's current include directory @var{include_dir}, the
+argument to the include directive @var{path}; and a pointer at which
+to return an error message @var{error}.
+
+On success, the function should return a @code{NULL}-terminated array
+of paths. Any relative paths must be relative to the program's current
+working directory. The contents of these files will be inlined at the point
+of inclusion, in the order that the paths appear in the
+array. Both the array and its elements should be heap allocated; the
+library will take ownership of and eventually free the strings in the
+array and the array itself.
+
+On failure, the function should return @code{NULL} and set @var{*error} to a
+static error string which should be used as the parse error for the
+configuration; the library does not take ownership of or free this string.
+
+The default include function, @code{config_default_include_func()},
+simply returns a @code{NULL}-terminated array containing either a copy
+of @var{path} if it's an absolute path, or a concatenation of
+@var{include_dir} and @var{path} if it's a relative path.
+
+@end deftypefun
+
+Application-supplied include functions can perform custom tasks like wildcard
+expansion or variable substitution. For example, consider the include directive:
+
+@cartouche
+@smallexample
+@@include "configs/*.cfg"
+@end smallexample
+@end cartouche
+
+The include function would be invoked with the path @samp{configs/*.cfg} and
+could do wildcard expansion on that path, returning a list of paths to files
+with the file extension @samp{.cfg} in the subdirectory @samp{configs}. Each of
+these files would then be inlined at the location of the include directive.
+
+Tasks like wildcard expansion and variable substitution are non-trivial to
+implement and typically require platform-specific code. In the interests of
+keeping the library as compact and platform-independent as possible,
+implementations of such include functions are not included.

+
+@table @code
+
+@item CONFIG_OPTION_AUTOCONVERT
+Turning this option on enables number auto-conversion for
+the configuration. When this feature is enabled, an attempt to retrieve a
+floating point setting's value into an integer (or vice versa), or
+store an integer to a floating point setting's value (or vice versa)
+will cause the library to silently perform the necessary conversion
+(possibly leading to loss of data), rather than reporting failure. By
+default this option is turned off.
+
+@item CONFIG_OPTION_SEMICOLON_SEPARATORS
+This option controls whether a semicolon (`;') is output after each setting
+when the configuration is written to a file or stream. (The semicolon
+separators are optional in the configuration syntax.) By default this
+option is turned on.
+
+@item CONFIG_OPTION_COLON_ASSIGNMENT_FOR_GROUPS
+This option controls whether a colon (`:') is output between each
+group setting's name and its value when the configuration is written to
+a file or stream. If the option is turned off, an equals sign (`=') is
+output instead. (These tokens are interchangeable in the configuration
+syntax.) By default this option is turned on.
+
+@item CONFIG_OPTION_COLON_ASSIGNMENT_FOR_NON_GROUPS
+This option controls whether a colon (`:') is output between each
+non-group setting's name and its value when the configuration is written
+to a file or stream. If the option is turned off, an equals sign (`=')
+is output instead. (These tokens are interchangeable in the configuration
+syntax.) By default this option is turned off.
+
+@item CONFIG_OPTION_OPEN_BRACE_ON_SEPARATE_LINE
+This option controls whether an open brace (`@{') will be written on its own
+line when the configuration is written to a file or stream. If the option is
+turned off, the brace will be written at the end of the previous line.
+By default this option is turned on.
+
+@item CONFIG_OPTION_ALLOW_SCIENTIFIC_NOTATION
+(@b{Since @i{v1.7}})
+This option controls whether scientific notation may be used as appropriate
+when writing floating point values (corresponding to @code{printf()}
+@samp{%g} format) or should never be used (corresponding to @code{printf()}
+@samp{%f} format). By default this option is turned off.
+
+@item CONFIG_OPTION_FSYNC
+(@b{Since @i{v1.7.1}})
+This option controls whether the @code{config_write_file()} function performs
+an @i{fsync} operation after writing the configuration and before closing the
+file. By default this option is turned off.
+
+@item CONFIG_OPTION_ALLOW_OVERRIDES
+(@b{Since @i{v1.7.3}})

+with the same name. If this option is turned off, duplicate settings are
+rejected. By default this option is turned off.

+
+@tindex Config
+@tindex Setting
+This chapter describes the C++ library API. The class @code{Config}
+represents a configuration, and the class @code{Setting} represents a
+configuration setting. Note that by design, neither of these classes
+provides a public copy constructor or assignment operator. Therefore,
+instances of these classes may only be passed between functions via
+references or pointers.
+
+@tindex ConfigException
+The library defines a group of exceptions, all of which extend the
+common base exception @code{ConfigException}.
+
+@tindex SettingTypeException
+A @code{SettingTypeException} is thrown when the type of a setting's
+value does not match the type requested.
+
+@deftypemethod SettingTypeException {} SettingTypeException (@w{const Setting &@var{setting}})
+@deftypemethodx SettingTypeException {} SettingTypeException (@w{const Setting &@var{setting}}, @w{int @var{index}})
+@deftypemethodx SettingTypeException {} SettingTypeException (@w{const Setting &@var{setting}}, @w{const char *@var{name}})
+
+These methods construct @code{SettingTypeException} objects for the given @var{setting} and/or member @var{index} or @var{name}.
+
+@end deftypemethod
+
+@tindex SettingNotFoundException
+A @code{SettingNotFoundException} is thrown when a setting is not found.
+
+@deftypemethod SettingNotFoundException {} SettingNotFoundException (@w{const Setting &@var{setting}}, @w{int @var{index}})
+@deftypemethodx SettingNotFoundException {} SettingNotFoundException (@w{const Setting &@var{setting}}, @w{const char *@var{name}})
+@deftypemethodx SettingNotFoundException {} SettingNotFoundException (@w{const char *@var{path}})
+
+These methods construct @code{SettingTypeException} objects for the given @var{setting} and member @var{index} or @var{name}, or path @var{path}.
+
+@end deftypemethod
+
+@tindex SettingNameException
+A @code{SettingNameException} is thrown when an attempt is made to add
+a new setting with a non-unique or invalid name.
+
+@deftypemethod SettingNameException {} SettingNameException (@w{const Setting &@var{setting}}, @w{const char *@var{name}})
+
+This method constructs a @code{SettingNameExcpetion} object for the given @var{setting} and member name @var{name}.
+
+@end deftypemethod
+
+@tindex ParseException
+A @code{ParseException} is thrown when a parse error occurs while
+reading a configuration from a stream.
+
+@deftypemethod ParseException {} ParseException (@w{const char *@var{file}}, @w{int @var{line}}, @w{const char *@var{error}})
+
+This method constructs a @code{ParseException} object with the given filename @var{file}, line number @var{line}, and error message @var{error}.
+
+@end deftypemethod
+
+@tindex FileIOException
+A @code{FileIOException} is thrown when an I/O error occurs while
+reading/writing a configuration from/to a file.
+
+@tindex SettingException
+@code{SettingTypeException}, @code{SettingNotFoundException}, and
+@code{SettingNameException} all extend the common base
+exception @code{SettingException}, which provides the following method:
+
+@deftypemethod SettingException {const char *} getPath () const
+
+This method returns the path to the setting associated with the exception, or
+@code{NULL} if there is no applicable path.
+
+@end deftypemethod
+
+The remainder of this chapter describes the methods for manipulating
+configurations and configuration settings.
+
+@deftypemethod Config {} Config ()
+@deftypemethodx Config {} ~Config ()
+
+These methods create and destroy @code{Config} objects. 
+
+@end deftypemethod
+
+@deftypemethod Config void clear ()
+
+@b{Since @i{v1.7}}
+
+This method clears the configuration. All child settings of the root
+setting are recursively destroyed. All other attributes of the
+configuration are left unchanged.
+
+@end deftypemethod
+
+@deftypemethod Config void read (@w{FILE * @var{stream}})
+@deftypemethodx Config void write (@w{FILE * @var{stream}}) const
+
+The @code{read()} method reads and parses a configuration from the given
+@var{stream}. A @code{ParseException} is thrown if a parse error occurs.
+
+The @code{write()} method writes the configuration to the given @var{stream}.
+
+@end deftypemethod
+
+@deftypemethod Config void readFile (@w{const char * @var{filename}})
+@deftypemethodx Config void readFile (@w{const std::string &@var{filename}})
+
+The @code{readFile()} method reads and parses a configuration from the
+file named @var{filename}. A @code{ParseException} is thrown if a
+parse error occurs. A @code{FileIOException} is thrown if the file
+cannot be read.
+
+@end deftypemethod
+
+@deftypemethod Config void writeFile (@w{const char * @var{filename}})
+@deftypemethodx Config void writeFile (@w{const std::string &@var{filename}})
+
+The @code{writeFile()} method writes the configuration to the file
+named @var{filename}. A @code{FileIOException} is thrown if the file cannot
+be written.
+
+@end deftypemethod
+
+@deftypemethod Config void readString (@w{const char * @var{str}})
+@deftypemethodx Config void readString (@w{const std::string &@var{str}})
+
+These methods read and parse a configuration from the string
+@var{str}. A @code{ParseException} is thrown if a parse error occurs.
+
+@end deftypemethod
+
+@deftypemethod ParseException {const char *} getError () const
+@deftypemethodx ParseException {const char *} getFile () const
+@deftypemethodx ParseException int getLine () const
+
+If a call to @code{readFile()}, @code{readString()}, or @code{read()}
+resulted in a @code{ParseException}, these methods can be called on
+the exception object to obtain the text, filename, and line number of
+the parse error. Storage for the strings returned by @code{getError()}
+and @code{getFile()} are managed by the library; the strings must not
+be freed by the caller.
+
+@end deftypemethod
+
+@deftypemethod Config void setIncludeDir (@w{const char *@var{includeDir}})
+@deftypemethodx Config {const char *} getIncludeDir () const
+
+The @code{setIncludeDir()} method specifies the include directory,
+@var{includeDir}, relative to which the files specified in
+@samp{@@include} directives will be located for the configuration. By
+default, there is no include directory, and all include files are
+expected to be relative to the current working directory. If
+@var{includeDir} is @code{NULL}, the default behavior is reinstated.
+
+For example, if the include directory is set to @file{/usr/local/etc},
+the include directive @samp{@@include "configs/extra.cfg"} would include the
+file @file{/usr/local/etc/configs/extra.cfg}.
+
+@code{getIncludeDir()} returns the current include directory for the
+configuration, or @code{NULL} if none is set.
+
+@end deftypemethod
+
+@deftypemethod Config {virtual const char **} evaluateIncludePath (@w{const char * @var{path}}, @w{const char ** @var{error}})
+
+@b{Since @i{v1.7}}
+
+This method is called to evaluate the path of an @code{@@include} directive.
+The @var{path} is the literal path argument of the directive. The method may
+be overridden in a subclass to perform tasks like wildcard expansion and
+variable substitution.
+
+On success, the method should return a @code{NULL}-terminated array of paths.
+Any relative paths must be relative to the program's current working directory.
+The contents of these files will be inlined at the point of inclusion, in the
+order that the paths appear in the array. Both the array and its elements should
+be heap allocated; the library will take ownership of and eventually free the
+strings in the array and the array itself.
+
+On failure, the function should return @code{NULL} and set @var{*error} to a
+static error string which should be used as the parse error for the
+configuration; the library does not take ownership of or free this string.
+
+The default implementation simply returns a @code{NULL}-terminated array
+containing either a copy of @var{path} if it's an absolute path, or a
+concatenation of the include directory and @var{path} if it's a relative path.
+
+For more information see @code{config_set_include_func()} above.

+
+@deftypemethod Config int getOptions () const
+@deftypemethodx Config void setOptions (int @var{options})
+
+@tindex Config::Option
+These methods get and set the options for the configuration. The
+options affect how configurations are read and written. The parameter
+@var{options} should be a bitwise-OR of the following @var{Config::Option}
+enumeration values:
+
+@table @code
+
+@item Config::OptionAutoConvert
+Turning this option on enables number auto-conversion for
+the configuration. When this feature is enabled, an attempt to retrieve a
+floating point setting's value into an integer (or vice versa), or
+store an integer to a floating point setting's value (or vice versa)
+will cause the library to silently perform the necessary conversion
+(possibly leading to loss of data), rather than reporting failure. By
+default this option is turned off.
+
+@item Config::OptionSemicolonSeparators
+This option controls whether a semicolon (`;') is output after each setting
+when the configuration is written to a file or stream. (The semicolon
+separators are optional in the configuration syntax.) By default this
+option is turned on.
+
+@item Config::OptionColonAssignmentForGroups
+This option controls whether a colon (`:') is output between each
+group setting's name and its value when the configuration is written to
+a file or stream. If the option is turned off, an equals sign (`=') is
+output instead. (These tokens are interchangeable in the configuration
+syntax.) By default this option is turned on.
+
+@item Config::OptionColonAssignmentForNonGroups
+This option controls whether a colon (`:') is output between each
+non-group setting's name and its value when the configuration is written
+to a file or stream. If the option is turned off, an equals sign (`=')
+is output instead. (These tokens are interchangeable in the configuration
+syntax.) By default this option is turned off.
+
+@item Config::OptionOpenBraceOnSeparateLine
+This option controls whether an open brace (`@{') will be written on its own
+line when the configuration is written to a file or stream. If the option is
+turned off, the brace will be written at the end of the previous line.
+By default this option is turned on.
+
+@item Config::OptionAllowScientificNotation
+(@b{Since @i{v1.7}})
+This option controls whether scientific notation may be used as appropriate
+when writing floating point values (corresponding to @code{printf()}
+@samp{%g} format) or should never be used (corresponding to @code{printf()}
+@samp{%f} format). By default this option is turned off.
+
+@item Config::OptionFsync
+(@b{Since @i{v1.7.1}})
+This option controls whether the @code{writeFile()} method performs an @i{fsync}
+operation after writing the configuration and before closing the file. By
+default this option is turned off.
+
+@item Config::OptionAllowOverrides
+(@b{Since @i{v1.7.3}})
+This option controls whether duplicate settings override previous settings
+with the same name. If this option is turned off, duplicate settings are
+rejected. By default this option is turned off.

+These methods get and set the tab width for the configuration. The tab
+width affects the formatting of the configuration when it is written
+to a file or stream: each level of nesting is indented by @var{width}
+spaces, or by a single tab character if @var{width} is 0. The tab
+width has no effect on parsing.
+
+Valid tab widths range from 0 to 15. The default tab width is 2.

+
+These are convenience methods for looking up the value of a setting
+with the given @var{path}. If the setting is found and is of an
+appropriate type, the value is stored in @var{value} and the method
+returns @code{true}. Otherwise, @var{value} is left unmodified and the
+method returns @code{false}. These methods do not throw exceptions.
+
+Storage for @w{@i{const char *}} values is managed by the library and
+released automatically when the setting is destroyed or when its value
+is changed; the string must not be freed by the caller. For safety and
+convenience, always assigning string values to a @code{std::string} is
+suggested.
+
+Since these methods have boolean return values and do not throw
+exceptions, they can be used within boolean logic expressions. The following
+example presents a concise way to look up three values at once and
+perform error handling if any of them are not found or are of the
+wrong type:
+
+@sp 1
+@cartouche
+@smallexample
+int var1;
+double var2;
+const char *var3;
+
+if(config.lookupValue("values.var1", var1)
+   && config.lookupValue("values.var2", var2)
+   && config.lookupValue("values.var3", var3))
+@{
+  // use var1, var2, var3
+@}
+else
+@{
+  // error handling here
+@}
+@end smallexample
+@end cartouche
+
+This approach also takes advantage of the short-circuit evaluation rules
+of C++, e.g., if the first lookup fails (returning @code{false}), the
+remaining lookups are skipped entirely.
+
+@end deftypemethod
+
+@deftypemethod Setting {} {operator bool ()} const
+@deftypemethodx Setting {} {operator int ()} const
+@deftypemethodx Setting {} {operator unsigned int ()} const

+@deftypemethodx Setting {} {operator unsigned long ()} const

+@deftypemethodx Setting {} {operator const char * ()} const
+@deftypemethodx Setting {} {operator std::string ()} const
+@deftypemethodx Setting {const char *} c_str () const
+
+These cast operators allow a @code{Setting} object to be assigned to a
+variable of type @i{bool} if it is of type @code{TypeBoolean};
+@i{int}, @i{unsigned int}; @code{long long} or @code{unsigned long long} if
+it is of type @code{TypeInt64}, @i{float} or @i{double} if it is of type
+@code{TypeFloat}; or @w{@i{const char *}} or @i{std::string} if it is
+of type @code{TypeString}.
+
+Values of type @code{TypeInt} or @code{TypeInt64} may be assigned to
+variables of type @i{long}, or @i{unsigned long}, depending on the
+sizes of those types on the host system.
+
+Storage for @w{@i{const char *}} return values is managed by the
+library and released automatically when the setting is destroyed or
+when its value is changed; the string must not be freed by the
+caller. For safety and convenience, always assigning string return
+values to a @code{std::string} is suggested.
+
+The following examples demonstrate this usage:
+
+@cartouche
+@smallexample
+long width = config.lookup("application.window.size.w");
+
+bool splashScreen = config.lookup("application.splash_screen");
+
+std::string title = config.lookup("application.window.title");
+@end smallexample
+@end cartouche
+
+Note that certain conversions can lead to loss of precision or
+clipping of values, e.g., assigning a negative value to an @i{unsigned
+int} (in which case the value will be treated as 0), or a
+double-precision value to a @i{float}. The library does not treat
+these lossy conversions as errors.
+
+Perhaps surprisingly, the following code in particular will cause a
+compiler error:
+
+@cartouche
+@smallexample
+std::string title;
+.
+.
+.
+title = config.lookup("application.window.title");
+@end smallexample
+@end cartouche
+
+This is because the assignment operator of @code{std::string} is being
+invoked with a @code{Setting &} as an argument. The compiler is unable
+to make an implicit conversion because both the @code{const char *}
+and the @code{std::string} cast operators of @code{Setting} are
+equally appropriate. This is not a bug in @i{libconfig}; providing
+only the @code{const char *} cast operator would resolve this
+particular ambiguity, but would cause assignments to
+@code{std::string} like the one in the previous example to produce a
+compiler error. (To understand why, see section 11.4.1 of @i{The C++
+Programming Language}.)
+
+The solution to this problem is to use an explicit conversion that
+avoids the construction of an intermediate @code{std::string} object,
+as follows:
+
+@cartouche
+@smallexample

+@deftypemethodx Setting {Setting &} operator= (@w{const char *@var{value}})

+
+These assignment operators allow values of type @i{bool}, @i{int},
+@i{long}, @i{long long}, @i{float}, @i{double}, @i{const char *}, and
+@i{std::string} to be assigned to a setting. In the case of strings,
+the library makes a copy of the passed string @var{value}, so it may
+be subsequently freed or modified by the caller without affecting the
+value of the setting.
+
+The following example code looks up a (presumably) integer setting
+and changes its value:
+
+@cartouche
+@smallexample
+Setting &setting = config.lookup("application.window.size.w");

+
+A @code{Setting} object may be subscripted with an integer index
+@var{index} if it is an array or list, or with either a string
+@var{name} or an integer index @var{index} if it is a group. For example,

+
+These are convenience methods for looking up the value of a child setting
+with the given @var{name}. If the setting is found and is of an
+appropriate type, the value is stored in @var{value} and the method
+returns @code{true}. Otherwise, @var{value} is left unmodified and the
+method returns @code{false}. These methods do not throw exceptions.
+
+Storage for @w{@i{const char *}} values is managed by the library and
+released automatically when the setting is destroyed or when its value
+is changed; the string must not be freed by the caller. For safety and
+convenience, always assigning string values to a @code{std::string} is
+suggested.
+
+Since these methods have boolean return values and do not throw
+exceptions, they can be used within boolean logic expressions. The following
+example presents a concise way to look up three values at once and
+perform error handling if any of them are not found or are of the
+wrong type:
+
+@sp 1
+@cartouche
+@smallexample
+int var1;
+double var2;
+const char *var3;
+
+if(setting.lookupValue("var1", var1)
+   && setting.lookupValue("var2", var2)
+   && setting.lookupValue("var3", var3))
+@{
+  // use var1, var2, var3
+@}
+else
+@{
+  // error handling here
+@}
+@end smallexample
+@end cartouche
+
+This approach also takes advantage of the short-circuit evaluation
+rules of C++, e.g., if the first lookup fails (returning @code{false}), the
+remaining lookups are skipped entirely.
+
+@end deftypemethod
+
+@deftypemethod Setting {Setting &} add (@w{const std::string &@var{name}}, @w{Setting::Type @var{type}})
+@deftypemethodx Setting {Setting &} add (@w{const char *@var{name}}, @w{Setting::Type @var{type}})
+
+These methods add a new child setting with the given @var{name} and
+@var{type} to the setting, which must be a group. They return a
+reference to the new setting. If the setting already has a child
+setting with the given name, or if the name is invalid, a
+@code{SettingNameException} is thrown. If the setting is not a group,
+a @code{SettingTypeException} is thrown.
+
+Once a setting has been created, neither its name nor type can be
+changed.
+
+@end deftypemethod
+
+@deftypemethod Setting {Setting &} add (@w{Setting::Type @var{type}})
+
+This method adds a new element to the setting, which must be of type
+@code{TypeArray} or @code{TypeList}. If the setting is an array which
+currently has zero elements, the @var{type} parameter (which must be
+@code{TypeInt}, @code{TypeInt64}, @code{TypeFloat}, @code{TypeBool},
+or @code{TypeString}) determines the type for the array; otherwise it
+must match the type of the existing elements in the array.
+
+The method returns the new setting on success. If @var{type} is a
+scalar type, the new setting will have a default value of 0, 0.0,
+@code{false}, or @code{NULL}, as appropriate.
+
+The method throws a @code{SettingTypeException} if the setting is not
+an array or list, or if @var{type} is invalid.
+
+@end deftypemethod
+
+@deftypemethod Setting void remove (@w{const std::string &@var{name}})
+@deftypemethodx Setting void remove (@w{const char *@var{name}})
+
+These methods remove the child setting with the given @var{name} from
+the setting, which must be a group. Any child settings of the removed
+setting are recursively destroyed as well.
+
+If the setting is not a group, a @code{SettingTypeException} is
+thrown.  If the setting does not have a child setting with the given
+name, a @code{SettingNotFoundException} is thrown.

+of the removed setting are recursively destroyed as well.
+
+If the setting is not a group, list, or array, a

+consider assigning the return value to a @code{std::string}.

+
+These methods get and set the external format for the setting.
+
+@tindex Setting::Format
+The @var{Setting::Format} enumeration consists of the following
+constants: @code{FormatDefault} and @code{FormatHex}. All settings
+support the @code{FormatDefault} format. The @code{FormatHex} format
+specifies hexadecimal formatting for integer values, and hence only
+applies to settings of type @code{TypeInt} and @code{TypeInt64}. If
+@var{format} is invalid for the given setting, it is ignored.

+@end deftypemethod
+
+@deftypemethod Setting bool exists (@w{const std::string &@var{name}}) const
+@deftypemethodx Setting bool exists (@w{const char *@var{name}}) const
+
+These methods test if the setting has a child setting with the given

+@page
+@deftypemethod Setting iterator begin ()
+@deftypemethodx Setting iterator end ()
+@deftypemethodx Setting const_iterator begin ()
+@deftypemethodx Setting const_iterator end ()

+or group, they throw a @code{SettingTypeException}.
+
+@end deftypemethod
+

+@deftypemethod Setting bool isAggregate () const
+@deftypemethodx Setting bool isScalar () const
+@deftypemethodx Setting bool isNumber () const

+
+These convenience methods test if a setting is of an aggregate type (a
+group, array, or list), of a scalar type (integer, 64-bit integer,
+floating point, boolean, or string), of a number (integer, 64-bit
+integer, or floating point), and of a string respectively.
+
+@end deftypemethod
+
+@deftypemethod Setting {const char *} getSourceFile () const
+
+This method returns the name of the file from which the setting was

+## About

+

+*Libconfig* is a simple library for processing structured configuration 

+files, like [this one](test.cfg.txt). This file format is more compact 

+and more readable than XML. And unlike XML, it is type-aware, so it is 

+not necessary to do string parsing in application code.

+

+*Libconfig* is very compact -- a fraction of the size of the _expat_ XML 

+parser library. This makes it well-suited for memory-constrained systems 

+like handheld devices.

+

+The library includes bindings for both the C and C++ languages. It works 

+on POSIX-compliant UNIX and UNIX-like systems (GNU/Linux, Mac OS X, 

+FreeBSD), Android, and Windows (2000, XP and later).

+<p><i>Libconfig</i> is a library for reading, manipulating, and writing
+structured configuration files. The library features a fully
+reentrant parser and includes bindings for both the C and C++
+programming languages.
+</p>
+<p>The library runs on modern POSIX-compilant systems, such as Linux,
+Solaris, and Mac OS X (Darwin), as well as on Microsoft Windows
+2000/XP and later (with either Microsoft Visual Studio 2005 or later,
+or the GNU toolchain via the MinGW environment).

+<h3 class="section">1.1 Why Another Configuration File Library?</h3>
+
+<p>There are several open-source configuration file libraries available
+as of this writing. This library was written because each of those
+libraries falls short in one or more ways. The main features of
+<i>libconfig</i> that set it apart from the other libraries are:
+</p>
+<ul>
+<li> A fully reentrant parser. Independent configurations can be parsed in concurrent threads at the same time.
+
+</li><li> Both C <i>and</i> C++ bindings, as well as hooks to allow for the creation of wrappers in other languages.
+
+</li><li> A simple, structured configuration file format that is more
+readable and compact than XML and more flexible than the obsolete but
+prevalent Windows &ldquo;INI&rdquo; file format.
+
+</li><li> A low-footprint implementation (just 37K for the C library and 76K for
+the C++ library) that is suitable for memory-constrained systems.
+
+</li><li> Proper documentation.

+
+<p><i>Libconfig</i> is fully <em>reentrant</em>; the functions in the library
+do not make use of global variables and do not maintain state between
+successive calls. Therefore two independent configurations may be safely
+manipulated concurrently by two distinct threads.
+</p>
+<p><i>Libconfig</i> is not <em>thread-safe</em>. The library is not aware of
+the presence of threads and knows nothing about the host system&rsquo;s
+threading model. Therefore, if an instance of a configuration is to be
+accessed from multiple threads, it must be suitably protected by
+synchronization mechanisms like read-write locks or mutexes; the
+standard rules for safe multithreaded access to shared data must be
+observed.
+</p>
+<p><i>Libconfig</i> is not <em>async-safe</em>. Calls should not be made into
+the library from signal handlers, because some of the C library
+routines that it uses may not be async-safe.
+</p>
+<p><i>Libconfig</i> is not guaranteed to be <em>cancel-safe</em>. Since it is
+not aware of the host system&rsquo;s threading model, the library does not
+contain any thread cancellation points. In most cases this will not be
+an issue for multithreaded programs. However, be aware that some of
+the routines in the library (namely those that read/write
+configurations from/to files or streams) perform I/O using C library
+routines which may potentially block; whether or not these C library
+routines are cancel-safe depends on the host system.

+<p><i>Libconfig</i> does not natively support Unicode configuration files,
+but string values may contain Unicode text encoded in UTF-8; such
+strings will be treated as ordinary 8-bit ASCII text by the
+library. It is the responsibility of the calling program to perform
+the necessary conversions to/from wide (<tt>wchar_t</tt>) strings using the
+wide string conversion functions such as <tt>mbsrtowcs()</tt> and
+<tt>wcsrtombs()</tt> or the <tt>iconv()</tt> function of the <i>libiconv</i>
+library.
+</p>
+<a name="index-locale"></a>
+<p>The textual representation of a floating point value varies by
+locale. However, the <i>libconfig</i> grammar specifies that
+floating point values are represented using a period (&lsquo;.&rsquo;) as the
+radix symbol; this is consistent with the grammar of most programming
+languages. When a configuration is read in or written out,
+<i>libconfig</i> temporarily changes the <tt>LC_NUMERIC</tt> category of the
+locale of the calling thread to the &ldquo;C&rdquo; locale to ensure consistent
+handling of floating point values regardless of the locale(s) in use
+by the calling program.
+</p>
+<p>Note that the MinGW environment does not (as of this writing) provide
+functions for changing the locale of the calling thread. Therefore,
+when using <i>libconfig</i> in that environment, the calling program is
+responsible for changing the <tt>LC_NUMERIC</tt> category of the locale to
+the &quot;C&quot; locale before reading or writing a configuration.

+
+<a name="index-pkg_002dconfig"></a>
+<p>On UNIX systems you can use the <i>pkg-config</i> utility (version 0.20
+or later) to automatically select the appropriate compiler and linker
+switches for <i>libconfig</i>. Ensure that the environment variable
+<code>PKG_CONFIG_PATH</code> contains the absolute path to the
+<samp>lib/pkgconfig</samp> subdirectory of the <i>libconfig</i> installation. Then,
+you can compile and link C programs with <i>libconfig</i> as follows:
+</p>
+<div class="smallexample">
+<pre class="smallexample">gcc `pkg-config --cflags libconfig` myprogram.c -o myprogram \
+    `pkg-config --libs libconfig`
+</pre></div>
+<br>
+
+<p>And similarly, for C++ programs:
+</p>
+<div class="smallexample">
+<pre class="smallexample">g++ `pkg-config --cflags libconfig++` myprogram.cpp -o myprogram \
+    `pkg-config --libs libconfig++`
+</pre></div>
+
+<br>
+<p>Note the backticks in the above examples.
+</p>
+<p>When using <b>autoconf</b>, the <code>PKG_CHECK_MODULES</code> m4 macro may be used to check for the presence of a given version of <i>libconfig</i>, and set the appropriate Makefile variables automatically. For example:
+</p>
+<div class="smallexample">
+<pre class="smallexample">PKG_CHECK_MODULES([LIBCONFIGXX], [libconfig++ &gt;= 1.4],,
+  AC_MSG_ERROR([libconfig++ 1.4 or newer not found.])
+)
+</pre></div>
+
+<p>In the above example, if <i>libconfig++</i> version 1.4 or newer is found,
+the Makefile variables <code>LIBCONFIGXX_LIBS</code> and <code>LIBCONFIGXX_CFLAGS</code> will be
+set to the appropriate compiler and linker flags for compiling with
+<i>libconfig</i>, and if it is not found, the configure script will abort
+with an error to that effect.

+following:
+</p>
+<ul>
+<li> A <em>scalar value</em>: integer, 64-bit integer, floating-point number, boolean,
+or string
+</li><li> An <em>array</em>, which is a sequence of scalar values, all of which must have the same type
+</li><li> A <em>group</em>, which is a collection of settings
+</li><li> A <em>list</em>, which is a sequence of values of any type, including other lists

+<p>Settings can be uniquely identified within the configuration by a
+<em>path</em>. The path is a dot-separated sequence of names, beginning
+at a top-level group and ending at the setting itself. Each name in
+the path is the name of a setting; if the setting has no name because
+it is an element in a list or array, an integer index in square
+brackets can be used as the name.
+</p>
+<p>For example, in our hypothetical configuration file, the path to the
+<code>x</code> setting is <code>application.window.pos.x</code>; the path to the
+<code>version</code> setting is simply <code>version</code>; and the path to the
+<code>title</code> setting of the second book in the <code>books</code> list is
+<code>application.books.[1].title</code>.
+</p>
+<p>The datatype of a value is determined from the format of the value
+itself. If the value is enclosed in double quotes, it is treated as a
+string. If it looks like an integer or floating point number, it is
+treated as such. If it is one of the values <code>TRUE</code>, <code>true</code>,
+<code>FALSE</code>, or <code>false</code> (or any other mixed-case version of
+those tokens, e.g., <code>True</code> or <code>FaLsE</code>), it is treated as a
+boolean. If it consists of a comma-separated list of values enclosed
+in square brackets, it is treated as an array. And if it consists of a
+comma-separated list of values enclosed in parentheses, it is treated
+as a list. Any value which does not meet any of these criteria is
+considered invalid and results in a parse error.
+</p>
+<p>All names are case-sensitive. They may consist only of alphanumeric
+characters, dashes (&lsquo;<samp>-</samp>&rsquo;), underscores (&lsquo;<samp>_</samp>&rsquo;), and asterisks
+(&lsquo;<samp>*</samp>&rsquo;), and must begin with a letter or asterisk. No other
+characters are allowed.
+</p>
+<p>In C and C++, integer, 64-bit integer, floating point, and string
+values are mapped to the native types <code>int</code>, <code>long long</code>,
+<code>double</code>, and <code>const char *</code>, respectively. The boolean type
+is mapped to <code>int</code> in C and <code>bool</code> in C++.

+<h3 class="section">2.6 64-bit Integer Values</h3>
+
+<p>Long long (64-bit) integers are represented identically to integers,
+except that an &lsquo;L&rsquo; character is appended to indicate a 64-bit
+value. For example, &lsquo;<samp>0L</samp>&rsquo; indicates a 64-bit integer value 0.  As
+of version 1.5 of the library, the trailing &lsquo;L&rsquo; is optional; if the
+integer value exceeds the range of a 32-bit integer, it will
+automatically be interpreted as a 64-bit integer.
+</p>
+<p>The <i>integer</i> and <i>64-bit integer</i> setting types are interchangeable to the
+extent that a conversion between the corresponding native types would not
+result in an overflow or underflow. For example, a <i>long long</i> value can be
+written to a setting that has an <i>integer</i> type, if that value is within the
+range of an <i>int</i>. This rule applies to every API function or method that
+reads a value from or writes a value to a setting: if the type conversion would
+not result in an overflow or underflow, then the call will succeed, and
+otherwise it will fail. This behavior was not well-defined prior to version 1.7
+of the library.

+</p>
+<p>In addition, the &lsquo;<samp>\x</samp>&rsquo; escape sequence is supported; this sequence
+must be followed by <i>exactly two</i> hexadecimal digits, which represent an
+8-bit ASCII value. For example, &lsquo;<samp>\xFF</samp>&rsquo; represents the character
+with ASCII code 0xFF.
+</p>
+<p>No other escape sequences are currently supported.
+</p>
+<p>Adjacent strings are automatically concatenated, as in C/C++ source
+code. This is useful for formatting very long strings as sequences of
+shorter strings. For example, the following constructs are equivalent:
+</p>
+<ul>
+<li> <code>&quot;The quick brown fox jumped over the lazy dog.&quot;</code>
+
+</li><li> <code>&quot;The quick brown fox&quot;</code> <br>

+
+<a name="index-include-directive"></a>
+<p>A configuration file may &ldquo;include&rdquo; the contents of other files
+using an <i>include directive</i>. This directive has the effect of
+inlining the contents of the named file(s) at the point of inclusion.
+</p>
+<p>An include directive must appear on its own line in the input. It has
+the form:
+</p>
+<p><b>@include &quot;</b><i>path</i><b>&quot;</b>
+</p>
+<a name="index-include-function"></a>
+<p>The interpretation of <i>path</i> depends on the currently registered
+<i>include function</i>. The default include function prepends the include
+directory, if any, to <i>path</i>, and then interprets the result as a single,
+literal file path. The application may supply its own include function which
+does variable substitution, wildcard expansion, or other transformations,
+returning a list of zero or more paths to files whose contents should be inlined
+at the point of inclusion.
+</p>
+<p>Any backslashes or double quotes in the path must be escaped as
+&lsquo;<samp>\\</samp>&rsquo; and &lsquo;<samp>\&quot;</samp>&rsquo;, respectively.
+</p>
+<p>For example, consider the following two configuration files:
+</p>
+<table class="cartouche" border="1"><tr><td>
+<div class="smallexample">
+<pre class="smallexample"># file: quote.cfg
+quote = &quot;Criticism may not be agreeable, but it is necessary.&quot;
+        &quot; It fulfils the same function as pain in the human&quot;
+        &quot; body. It calls attention to an unhealthy state of&quot;
+        &quot; things.\n&quot;
+        &quot;\t--Winston Churchill&quot;;
+</pre></div>
+</td></tr></table>
+
+<table class="cartouche" border="1"><tr><td>
+<div class="smallexample">
+<pre class="smallexample"># file: test.cfg
+info: {
+  name = &quot;Winston Churchill&quot;;
+  @include &quot;quote.cfg&quot;
+  country = &quot;UK&quot;;
+};
+</pre></div>
+</td></tr></table>
+
+<p>The resulting configuration will be equivalent to one in which the
+contents of the file &lsquo;<samp>quote.cfg</samp>&rsquo; appeared at the point where the
+include directive is placed.
+</p>
+<p>Include files may be nested to a maximum of 10 levels; exceeding this
+limit results in a parse error.
+</p>
+<p>When the path argument to an <b>@include</b> directive is a relative

+directory that has been been set by means of
+<code>config_set_include_dir()</code>. If no include directory has been set,
+then it will be taken as being relative to the program&rsquo;s current
+working directory.
+</p>
+<p>Like comments, include directives are not part of the configuration
+file syntax. They are processed before the configuration itself is
+parsed. Therefore, they are not preserved when the configuration is
+written back out to a stream. There is presently no support for
+programmatically inserting include directives into a configuration.

+argument to the include directive <var>path</var>; and a pointer at which
+to return an error message <var>error</var>.
+</p>
+<p>On success, the function should return a <code>NULL</code>-terminated array

+of inclusion, in the order that the paths appear in the

+library will take ownership of and eventually free the strings in the
+array and the array itself.

+<p>On failure, the function should return <code>NULL</code> and set <var>*error</var> to a
+static error string which should be used as the parse error for the
+configuration; the library does not take ownership of or free this string.

+<var>include_dir</var> and <var>path</var> if it&rsquo;s a relative path.
+</p>

+
+<p>Application-supplied include functions can perform custom tasks like wildcard
+expansion or variable substitution. For example, consider the include directive:
+</p>
+<table class="cartouche" border="1"><tr><td>
+<div class="smallexample">
+<pre class="smallexample">@include &quot;configs/*.cfg&quot;
+</pre></div>
+</td></tr></table>
+
+<p>The include function would be invoked with the path &lsquo;<samp>configs/*.cfg</samp>&rsquo; and
+could do wildcard expansion on that path, returning a list of paths to files
+with the file extension &lsquo;<samp>.cfg</samp>&rsquo; in the subdirectory &lsquo;<samp>configs</samp>&rsquo;. Each of
+these files would then be inlined at the location of the include directive.
+</p>
+<p>Tasks like wildcard expansion and variable substitution are non-trivial to
+implement and typically require platform-specific code. In the interests of
+keeping the library as compact and platform-independent as possible,
+implementations of such include functions are not included.

+of type <code>TypeString</code>.
+</p>
+<p>Values of type <code>TypeInt</code> or <code>TypeInt64</code> may be assigned to

+sizes of those types on the host system.

+<p>Storage for <i>const&nbsp;char&nbsp;*</i><!-- /@w --> return values is managed by the
+library and released automatically when the setting is destroyed or
+when its value is changed; the string must not be freed by the

+values to a <code>std::string</code> is suggested.
+</p>
+<p>The following examples demonstrate this usage:

+<table class="cartouche" border="1"><tr><td>
+<div class="smallexample">
+<pre class="smallexample">long width = config.lookup(&quot;application.window.size.w&quot;);
+
+bool splashScreen = config.lookup(&quot;application.splash_screen&quot;);
+
+std::string title = config.lookup(&quot;application.window.title&quot;);
+</pre></div>
+</td></tr></table>
+
+<p>Note that certain conversions can lead to loss of precision or
+clipping of values, e.g., assigning a negative value to an <i>unsigned
+int</i> (in which case the value will be treated as 0), or a
+double-precision value to a <i>float</i>. The library does not treat
+these lossy conversions as errors.
+</p>
+<p>Perhaps surprisingly, the following code in particular will cause a
+compiler error:
+</p>
+<table class="cartouche" border="1"><tr><td>
+<div class="smallexample">
+<pre class="smallexample">std::string title;
+.
+.

+title = config.lookup(&quot;application.window.title&quot;);
+</pre></div>
+</td></tr></table>
+
+<p>This is because the assignment operator of <code>std::string</code> is being
+invoked with a <code>Setting &amp;</code> as an argument. The compiler is unable
+to make an implicit conversion because both the <code>const char *</code>
+and the <code>std::string</code> cast operators of <code>Setting</code> are
+equally appropriate. This is not a bug in <i>libconfig</i>; providing
+only the <code>const char *</code> cast operator would resolve this
+particular ambiguity, but would cause assignments to
+<code>std::string</code> like the one in the previous example to produce a
+compiler error. (To understand why, see section 11.4.1 of <i>The C++
+Programming Language</i>.)
+</p>
+<p>The solution to this problem is to use an explicit conversion that
+avoids the construction of an intermediate <code>std::string</code> object,
+as follows:
+</p>
+<table class="cartouche" border="1"><tr><td>
+<div class="smallexample">
+<pre class="smallexample">std::string title;
+.
+.
+.
+title = (const char *)config.lookup(&quot;application.window.title&quot;);
+</pre></div>
+</td></tr></table>
+
+<p>Or, alternatively, use the <code>c_str()</code> method, which has the same effect:
+</p>
+<table class="cartouche" border="1"><tr><td>
+<div class="smallexample">
+<pre class="smallexample">std::string title;
+.
+.
+.
+title = config.lookup(&quot;application.window.title&quot;).c_str();

+</p>
+<p>Everyone is permitted to copy and distribute verbatim copies of this
+license document, but changing it is not allowed.
+</p>
+<p>[This is the first released version of the Lesser GPL.  It also counts
+as the successor of the GNU Library Public License, version 2, hence the
+version number 2.1.]
+</p>
+<br>
+<div align="center">Preamble
+</div><br>
+
+<p>The licenses for most software are designed to take away your freedom to
+share and change it.  By contrast, the GNU General Public Licenses are
+intended to guarantee your freedom to share and change free software&ndash;to
+make sure the software is free for all its users.
+</p>
+<p>This license, the Lesser General Public License, applies to some
+specially designated software packages&ndash;typically libraries&ndash;of the Free
+Software Foundation and other authors who decide to use it.  You can use
+it too, but we suggest you first think carefully about whether this
+license or the ordinary General Public License is the better strategy to
+use in any particular case, based on the explanations below.
+</p>
+<p>When we speak of free software, we are referring to freedom of use, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish); that you receive source code or can get it if
+you want it; that you can change the software and use pieces of it in
+new free programs; and that you are informed that you can do these
+things.
+</p>
+<p>To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+</p>
+<p>For example, if you distribute copies of the library, whether gratis or
+for a fee, you must give the recipients all the rights that we gave you.
+You must make sure that they, too, receive or can get the source code.
+If you link other code with the library, you must provide complete
+object files to the recipients, so that they can relink them with the
+library after making changes to the library and recompiling it.  And you
+must show them these terms so they know their rights.
+</p>
+<p>We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+</p>
+<p>To protect each distributor, we want to make it very clear that there is
+no warranty for the free library.  Also, if the library is modified by
+someone else and passed on, the recipients should know that what they
+have is not the original version, so that the original author&rsquo;s
+reputation will not be affected by problems that might be introduced by
+others.
+</p>
+<p>Finally, software patents pose a constant threat to the existence of any
+free program.  We wish to make sure that a company cannot effectively
+restrict the users of a free program by obtaining a restrictive license
+from a patent holder.  Therefore, we insist that any patent license
+obtained for a version of the library must be consistent with the full
+freedom of use specified in this license.
+</p>
+<p>Most GNU software, including some libraries, is covered by the ordinary
+GNU General Public License.  This license, the GNU Lesser General Public
+License, applies to certain designated libraries, and is quite different
+from the ordinary General Public License.  We use this license for
+certain libraries in order to permit linking those libraries into
+non-free programs.
+</p>
+<p>When a program is linked with a library, whether statically or using a
+shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the entire
+combination fits its criteria of freedom.  The Lesser General Public
+License permits more lax criteria for linking other code with the
+library.
+</p>
+<p>We call this license the &ldquo;Lesser&rdquo; General Public License because it does
+Less to protect the user&rsquo;s freedom than the ordinary General Public
+License.  It also provides other free software developers Less of an
+advantage over competing non-free programs.  These disadvantages are the
+reason we use the ordinary General Public License for many libraries.
+However, the Lesser license provides advantages in certain special
+circumstances.
+</p>
+<p>For example, on rare occasions, there may be a special need to encourage
+the widest possible use of a certain library, so that it becomes a
+de-facto standard.  To achieve this, non-free programs must be allowed
+to use the library.  A more frequent case is that a free library does
+the same job as widely used non-free libraries.  In this case, there is
+little to gain by limiting the free library to free software only, so we
+use the Lesser General Public License.
+</p>
+<p>In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of free
+software.  For example, permission to use the GNU C Library in non-free
+programs enables many more people to use the whole GNU operating system,
+as well as its variant, the GNU/Linux operating system.
+</p>
+<p>Although the Lesser General Public License is Less protective of the
+users&rsquo; freedom, it does ensure that the user of a program that is linked
+with the Library has the freedom and the wherewithal to run that program
+using a modified version of the Library.
+</p>
+<p>The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+&ldquo;work based on the library&rdquo; and a &ldquo;work that uses the library&rdquo;.  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+</p>
+
+<div align="center">GNU LESSER GENERAL PUBLIC LICENSE
+</div><div align="center">TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+</div>
+<ol>
+<li>
+<br>
+</li><li> This License Agreement applies to any software library or other program
+which contains a notice placed by the copyright holder or other
+authorized party saying it may be distributed under the terms of this
+Lesser General Public License (also called &ldquo;this License&rdquo;).  Each
+licensee is addressed as &ldquo;you&rdquo;.
+
+<p>A &ldquo;library&rdquo; means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+</p>
+<p>The &ldquo;Library&rdquo;, below, refers to any such software library or work which
+has been distributed under these terms.  A &ldquo;work based on the Library&rdquo;
+means either the Library or any derivative work under copyright law:
+that is to say, a work containing the Library or a portion of it, either
+verbatim or with modifications and/or translated straightforwardly into
+another language.  (Hereinafter, translation is included without
+limitation in the term &ldquo;modification&rdquo;.)
+</p>
+<p>&ldquo;Source code&rdquo; for a work means the preferred form of the work for making
+modifications to it.  For a library, complete source code means all the
+source code for all modules it contains, plus any associated interface
+definition files, plus the scripts used to control compilation and
+installation of the library.
+</p>
+<p>Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of running
+a program using the Library is not restricted, and output from such a
+program is covered only if its contents constitute a work based on the
+Library (independent of the use of the Library in a tool for writing
+it).  Whether that is true depends on what the Library does and what the
+program that uses the Library does.
+</p>
+<br>
+</li><li> You may copy and distribute verbatim copies of the Library&rsquo;s complete
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the notices
+that refer to this License and to the absence of any warranty; and
+distribute a copy of this License along with the Library.
+
+<p>You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+</p>
+<br>
+</li><li> You may modify your copy or copies of the Library or any portion of it,
+thus forming a work based on the Library, and copy and distribute such
+modifications or work under the terms of Section 1 above, provided that
+you also meet all of these conditions:
+
+<ol>
+<li> The modified work must itself be a software library.
+
+<br>
+</li><li> You must cause the files modified to carry prominent notices stating
+that you changed the files and the date of any change.
+
+<br>
+</li><li> You must cause the whole of the work to be licensed at no charge to all
+third parties under the terms of this License.
+
+<br>
+</li><li> If a facility in the modified Library refers to a function or a table of
+data to be supplied by an application program that uses the facility,
+other than as an argument passed when the facility is invoked, then you
+must make a good faith effort to ensure that, in the event an
+application does not supply such function or table, the facility still
+operates, and performs whatever part of its purpose remains meaningful.
+
+<p>(For example, a function in a library to compute square roots has a
+purpose that is entirely well-defined independent of the application.
+Therefore, Subsection 2d requires that any application-supplied function
+or table used by this function must be optional: if the application does
+not supply it, the square root function must still compute square
+roots.)
+</p>
+</li></ol>
+
+<p>These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library, and
+can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based on
+the Library, the distribution of the whole must be on the terms of this
+License, whose permissions for other licensees extend to the entire
+whole, and thus to each and every part regardless of who wrote it.
+</p>
+<p>Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+</p>
+<p>In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of a
+storage or distribution medium does not bring the other work under the
+scope of this License.
+</p>
+<br>
+</li><li> You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so that
+they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+<p>Once this change is made in a given copy, it is irreversible for that
+copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+</p>
+<p>This option is useful when you wish to copy part of the code of the
+Library into a program that is not a library.
+</p>
+<br>
+</li><li> You may copy and distribute the Library (or a portion or derivative of
+it, under Section 2) in object code or executable form under the terms
+of Sections 1 and 2 above provided that you accompany it with the
+complete corresponding machine-readable source code, which must be
+distributed under the terms of Sections 1 and 2 above on a medium
+customarily used for software interchange.
+
+<p>If distribution of object code is made by offering access to copy from a
+designated place, then offering equivalent access to copy the source
+code from the same place satisfies the requirement to distribute the
+source code, even though third parties are not compelled to copy the
+source along with the object code.
+</p>
+<br>
+</li><li> A program that contains no derivative of any portion of the Library, but
+is designed to work with the Library by being compiled or linked with
+it, is called a &ldquo;work that uses the Library&rdquo;.  Such a work, in
+isolation, is not a derivative work of the Library, and therefore falls
+outside the scope of this License.
+
+<p>However, linking a &ldquo;work that uses the Library&rdquo; with the Library creates
+an executable that is a derivative of the Library (because it contains
+portions of the Library), rather than a &ldquo;work that uses the library&rdquo;.
+The executable is therefore covered by this License.  Section 6 states
+terms for distribution of such executables.
+</p>
+<p>When a &ldquo;work that uses the Library&rdquo; uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be linked
+without the Library, or if the work is itself a library.  The threshold
+for this to be true is not precisely defined by law.
+</p>
+<p>If such an object file uses only numerical parameters, data structure
+layouts and accessors, and small macros and small inline functions (ten
+lines or less in length), then the use of the object file is
+unrestricted, regardless of whether it is legally a derivative work.
+(Executables containing this object code plus portions of the Library
+will still fall under Section 6.)
+</p>
+<p>Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6, whether
+or not they are linked directly with the Library itself.
+</p>
+<br>
+</li><li> As an exception to the Sections above, you may also combine or link a
+&ldquo;work that uses the Library&rdquo; with the Library to produce a work
+containing portions of the Library, and distribute that work under terms
+of your choice, provided that the terms permit modification of the work
+for the customer&rsquo;s own use and reverse engineering for debugging such
+modifications.
+
+<p>You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+</p>
+<ol>
+<li>
+<br>
+</li><li> Accompany the work with the complete corresponding machine-readable
+source code for the Library including whatever changes were used in the
+work (which must be distributed under Sections 1 and 2 above); and, if
+the work is an executable linked with the Library, with the complete
+machine-readable &ldquo;work that uses the Library&rdquo;, as object code and/or
+source code, so that the user can modify the Library and then relink to
+produce a modified executable containing the modified Library.  (It is
+understood that the user who changes the contents of definitions files
+in the Library will not necessarily be able to recompile the application
+to use the modified definitions.)
+
+<br>
+</li><li> Use a suitable shared library mechanism for linking with the Library.  A
+suitable mechanism is one that (1) uses at run time a copy of the
+library already present on the user&rsquo;s computer system, rather than
+copying library functions into the executable, and (2) will operate
+properly with a modified version of the library, if the user installs
+one, as long as the modified version is interface-compatible with the
+version that the work was made with.
+
+<br>
+</li><li> Accompany the work with a written offer, valid for at least three years,
+to give the same user the materials specified in Subsection 6a, above,
+for a charge no more than the cost of performing this distribution.
+
+<br>
+</li><li> If distribution of the work is made by offering access to copy from a
+designated place, offer equivalent access to copy the above specified
+materials from the same place.
+
+<br>
+</li><li> Verify that the user has already received a copy of these materials or
+that you have already sent this user a copy.
+
+</li></ol>
+
+<p>For an executable, the required form of the &ldquo;work that uses the Library&rdquo;
+must include any data and utility programs needed for reproducing the
+executable from it.  However, as a special exception, the materials to
+be distributed need not include anything that is normally distributed
+(in either source or binary form) with the major components (compiler,
+kernel, and so on) of the operating system on which the executable runs,
+unless that component itself accompanies the executable.
+</p>
+<p>It may happen that this requirement contradicts the license restrictions
+of other proprietary libraries that do not normally accompany the
+operating system.  Such a contradiction means you cannot use both them
+and the Library together in an executable that you distribute.
+</p>
+<br>
+</li><li> You may place library facilities that are a work based on the Library
+side-by-side in a single library together with other library facilities
+not covered by this License, and distribute such a combined library,
+provided that the separate distribution of the work based on the Library
+and of the other library facilities is otherwise permitted, and provided
+that you do these two things:
+
+<ol>
+<li>
+<br>
+</li><li> Accompany the combined library with a copy of the same work based on the
+Library, uncombined with any other library facilities.  This must be
+distributed under the terms of the Sections above.
+
+<br>
+</li><li> Give prominent notice with the combined library of the fact that part of
+it is a work based on the Library, and explaining where to find the
+accompanying uncombined form of the same work.
+
+</li></ol>
+
+<br>
+</li><li> You may not copy, modify, sublicense, link with, or distribute the
+Library except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense, link with, or distribute the
+Library is void, and will automatically terminate your rights under this
+License.  However, parties who have received copies, or rights, from you
+under this License will not have their licenses terminated so long as
+such parties remain in full compliance.
+
+<br>
+</li><li> You are not required to accept this License, since you have not signed
+it.  However, nothing else grants you permission to modify or distribute
+the Library or its derivative works.  These actions are prohibited by
+law if you do not accept this License.  Therefore, by modifying or
+distributing the Library (or any work based on the Library), you
+indicate your acceptance of this License to do so, and all its terms and
+conditions for copying, distributing or modifying the Library or works
+based on it.
+
+<br>
+</li><li> Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients&rsquo; exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+<br>
+</li><li> If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent license
+would not permit royalty-free redistribution of the Library by all those
+who receive copies directly or indirectly through you, then the only way
+you could satisfy both it and this License would be to refrain entirely
+from distribution of the Library.
+
+<p>If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply, and the section as a whole is intended to apply in other
+circumstances.
+</p>
+<p>It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is implemented
+by public license practices.  Many people have made generous
+contributions to the wide range of software distributed through that
+system in reliance on consistent application of that system; it is up to
+the author/donor to decide if he or she is willing to distribute
+software through any other system and a licensee cannot impose that
+choice.
+</p>
+<p>This section is intended to make thoroughly clear what is believed to be
+a consequence of the rest of this License.
+</p>
+<br>
+</li><li> If the distribution and/or use of the Library is restricted in certain
+countries either by patents or by copyrighted interfaces, the original
+copyright holder who places the Library under this License may add an
+explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+<br>
+</li><li> The Free Software Foundation may publish revised and/or new versions of
+the Lesser General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in
+detail to address new problems or concerns.
+
+<p>Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and &ldquo;any
+later version&rdquo;, you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a license
+version number, you may choose any version ever published by the Free
+Software Foundation.
+</p>
+<br>
+</li><li> If you wish to incorporate parts of the Library into other free programs
+whose distribution conditions are incompatible with these, write to the
+author to ask for permission.  For software which is copyrighted by the
+Free Software Foundation, write to the Free Software Foundation; we
+sometimes make exceptions for this.  Our decision will be guided by the
+two goals of preserving the free status of all derivatives of our free
+software and of promoting the sharing and reuse of software generally.
+
+<br>
+<div align="center">NO WARRANTY
+</div><br>
+
+</li><li> BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
+THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE LIBRARY &ldquo;AS IS&rdquo; WITHOUT WARRANTY OF ANY KIND, EITHER
+EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED
+WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE
+ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH
+YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
+NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+<br>
+</li><li> IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
+DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
+DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY
+(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
+INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF
+THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR
+OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

+<div align="center">How to Apply These Terms to Your New Libraries
+</div>
+<p>If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of
+the ordinary General Public License).
+</p>
+<p>To apply these terms, attach the following notices to the library.  It
+is safest to attach them to the start of each source file to most
+effectively convey the exclusion of warranty; and each file should have
+at least the &ldquo;copyright&rdquo; line and a pointer to where the full notice is
+found.

+       previous inconsistent state, consistent state with a non-default
+       action, or user semantic action that manipulated yychar.

+%description
+%{name} is a simple library for processing structured configuration
+files. The file format is more compact and more readable than XML. And
+unlike XML, it is type-aware, so it is not necessary to do string
+parsing in application code. The library includes bindings for both
+the C and C++ languages. It works on POSIX-compliant UNIX systems.
