* Issue #14: HashedDictionary may free memory twice if implicitly copied.
* Add private copy constructor and assignment operator for HashedDictionary.
* Issue #18: Building RPM package fails on Fedora 9: Installed (but
unpackaged) file vcdiff.1.gz.
* Some OS, including Fedora 9, automatically compress man pages that are
installed using /usr/bin/install. This confuses the RPM packager, which
expects a file named "vcdiff.1" and finds one named "vcdiff.1.gz" instead.
Use a wild-card character to accept either of these two alternatives.
* Change the VCDIFF block size to 16, but have the encoder discard all matches
smaller than 32 bytes. This doubles the CPU and memory needed by the
encoder, but finds better string matches, producing a more efficient
encoding. Loosen the timing test limit in blockhash_test.cc for the debug
build only.
* Make the code table writer a virtual interface.
* Add an interface SetTargetMatching() to the simple encoder class
VCDEncoder.
* Remove all references to LOG and logging.h from the unit tests and
command-line client.
* Remove all special cases for kBlockSize < 4. kBlockSize must be a multiple
of the machine word size (see blockhash.cc), so it will never be smaller
than 4.
* Use version 1.10 of Automake.
* Incorporate recent changes to gflags package
(http://code.google.com/p/google-gflags/)
* Fix Visual Studio type-mismatch warning in vcdecoder4_test.cc.
* Use address cache helper functions IsSameMode(), IsHereMode(), etc. to
simplify test code.
* Add contributor's name to THANKS file.

* Issue #6: vcdiff crashes with zero-size dictionary
* Add special cases for empty dictionary file in vcdiff_main.cc.
* Issue #7: vcdiff incorrect binary I/O on Windows
* Change stdin/stdout file type to binary in vcdiff_main.cc.
* Issue #13: Add unit test for vcdiff command-line executable
* Unit test vcdiff_test.bat added for Visual Studio testing of vcdiff.exe.
Includes regression tests for issues #6 and #7.
* Issue #15: open-vcdiff fails to compile on Fedora 9
* Apply patch sent by Daniel Kegel
* Add header <string.h> to src/vcdiffengine.cc, which uses memcpy.
* Remove const qualifier from integral return types to fix gcc 4.3.1
warning.
* Add contributors' names to THANKS file.

* Issue #15: open-vcdiff fails to compile on Fedora 9
* Add header <string.h> to source files that use memcmp, memset, memcpy,
and/or strlen.
* Change C++-style includes like <cstdlib> to C-style includes like
<stdlib.h> so that function names are guaranteed to be defined
in the global namespace.
* Issue #8: Decoder should not crash if it runs out of memory
* Add a new interface that places a limit on the maximum bytes allowed in
a single target window or a target file.
* Issue #13: Add unit test for vcdiff command-line executable
* Unit test vcdiff_test.sh added for Linux and Mac builds.
* Still need to add a Windows version of this test.

* Fix problems found on OpenBSD platform.
* Issue #1: vcdiff command-line executable crashes on startup.
This was a problem with the stub intended to replace pthread_once if the
package was not linked with the pthreads library. Simplify gflags.cc to
assume single-threaded execution.
* Issue #2: Unit test blockhash_test fails.
Define VCDIFF_USE_BLOCK_COMPARE_WORDS for BSD platforms to ensure that
the most efficient version of memcmp is used in the encoder's inner loop.
* Fix compilation warnings in gtest-filepath.cc: "warning: missing
initializer for member 'stat::...'"

* open-vcdiff: initial release:
The open-vcdiff package provides an encoder and decoder for the VCDIFF format
described in RFC 3284 (http://www.ietf.org/rfc/rfc3284.txt).
