+    Eclipse Public License - v 1.0
+
+THE ACCOMPANYING PROGRAM IS PROVIDED UNDER THE TERMS OF THIS ECLIPSE
+PUBLIC LICENSE ("AGREEMENT"). ANY USE, REPRODUCTION OR DISTRIBUTION OF
+THE PROGRAM CONSTITUTES RECIPIENT'S ACCEPTANCE OF THIS AGREEMENT.
+
+*1. DEFINITIONS*
+
+"Contribution" means:
+
+a) in the case of the initial Contributor, the initial code and
+documentation distributed under this Agreement, and
+
+b) in the case of each subsequent Contributor:
+
+i) changes to the Program, and
+
+ii) additions to the Program;
+
+where such changes and/or additions to the Program originate from and
+are distributed by that particular Contributor. A Contribution
+'originates' from a Contributor if it was added to the Program by such
+Contributor itself or anyone acting on such Contributor's behalf.
+Contributions do not include additions to the Program which: (i) are
+separate modules of software distributed in conjunction with the Program
+under their own license agreement, and (ii) are not derivative works of
+the Program.
+
+"Contributor" means any person or entity that distributes the Program.
+
+"Licensed Patents" mean patent claims licensable by a Contributor which
+are necessarily infringed by the use or sale of its Contribution alone
+or when combined with the Program.
+
+"Program" means the Contributions distributed in accordance with this
+Agreement.
+
+"Recipient" means anyone who receives the Program under this Agreement,
+including all Contributors.
+
+*2. GRANT OF RIGHTS*
+
+a) Subject to the terms of this Agreement, each Contributor hereby
+grants Recipient a non-exclusive, worldwide, royalty-free copyright
+license to reproduce, prepare derivative works of, publicly display,
+publicly perform, distribute and sublicense the Contribution of such
+Contributor, if any, and such derivative works, in source code and
+object code form.
+
+b) Subject to the terms of this Agreement, each Contributor hereby
+grants Recipient a non-exclusive, worldwide, royalty-free patent license
+under Licensed Patents to make, use, sell, offer to sell, import and
+otherwise transfer the Contribution of such Contributor, if any, in
+source code and object code form. This patent license shall apply to the
+combination of the Contribution and the Program if, at the time the
+Contribution is added by the Contributor, such addition of the
+Contribution causes such combination to be covered by the Licensed
+Patents. The patent license shall not apply to any other combinations
+which include the Contribution. No hardware per se is licensed hereunder.
+
+c) Recipient understands that although each Contributor grants the
+licenses to its Contributions set forth herein, no assurances are
+provided by any Contributor that the Program does not infringe the
+patent or other intellectual property rights of any other entity. Each
+Contributor disclaims any liability to Recipient for claims brought by
+any other entity based on infringement of intellectual property rights
+or otherwise. As a condition to exercising the rights and licenses
+granted hereunder, each Recipient hereby assumes sole responsibility to
+secure any other intellectual property rights needed, if any. For
+example, if a third party patent license is required to allow Recipient
+to distribute the Program, it is Recipient's responsibility to acquire
+that license before distributing the Program.
+
+d) Each Contributor represents that to its knowledge it has sufficient
+copyright rights in its Contribution, if any, to grant the copyright
+license set forth in this Agreement.
+
+*3. REQUIREMENTS*
+
+A Contributor may choose to distribute the Program in object code form
+under its own license agreement, provided that:
+
+a) it complies with the terms and conditions of this Agreement; and
+
+b) its license agreement:
+
+i) effectively disclaims on behalf of all Contributors all warranties
+and conditions, express and implied, including warranties or conditions
+of title and non-infringement, and implied warranties or conditions of
+merchantability and fitness for a particular purpose;
+
+ii) effectively excludes on behalf of all Contributors all liability for
+damages, including direct, indirect, special, incidental and
+consequential damages, such as lost profits;
+
+iii) states that any provisions which differ from this Agreement are
+offered by that Contributor alone and not by any other party; and
+
+iv) states that source code for the Program is available from such
+Contributor, and informs licensees how to obtain it in a reasonable
+manner on or through a medium customarily used for software exchange.
+
+When the Program is made available in source code form:
+
+a) it must be made available under this Agreement; and
+
+b) a copy of this Agreement must be included with each copy of the Program.
+
+Contributors may not remove or alter any copyright notices contained
+within the Program.
+
+Each Contributor must identify itself as the originator of its
+Contribution, if any, in a manner that reasonably allows subsequent
+Recipients to identify the originator of the Contribution.
+
+*4. COMMERCIAL DISTRIBUTION*
+
+Commercial distributors of software may accept certain responsibilities
+with respect to end users, business partners and the like. While this
+license is intended to facilitate the commercial use of the Program, the
+Contributor who includes the Program in a commercial product offering
+should do so in a manner which does not create potential liability for
+other Contributors. Therefore, if a Contributor includes the Program in
+a commercial product offering, such Contributor ("Commercial
+Contributor") hereby agrees to defend and indemnify every other
+Contributor ("Indemnified Contributor") against any losses, damages and
+costs (collectively "Losses") arising from claims, lawsuits and other
+legal actions brought by a third party against the Indemnified
+Contributor to the extent caused by the acts or omissions of such
+Commercial Contributor in connection with its distribution of the
+Program in a commercial product offering. The obligations in this
+section do not apply to any claims or Losses relating to any actual or
+alleged intellectual property infringement. In order to qualify, an
+Indemnified Contributor must: a) promptly notify the Commercial
+Contributor in writing of such claim, and b) allow the Commercial
+Contributor to control, and cooperate with the Commercial Contributor
+in, the defense and any related settlement negotiations. The Indemnified
+Contributor may participate in any such claim at its own expense.
+
+For example, a Contributor might include the Program in a commercial
+product offering, Product X. That Contributor is then a Commercial
+Contributor. If that Commercial Contributor then makes performance
+claims, or offers warranties related to Product X, those performance
+claims and warranties are such Commercial Contributor's responsibility
+alone. Under this section, the Commercial Contributor would have to
+defend claims against the other Contributors related to those
+performance claims and warranties, and if a court requires any other
+Contributor to pay any damages as a result, the Commercial Contributor
+must pay those damages.
+
+*5. NO WARRANTY*
+
+EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, THE PROGRAM IS PROVIDED
+ON AN "AS IS" BASIS, WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND,
+EITHER EXPRESS OR IMPLIED INCLUDING, WITHOUT LIMITATION, ANY WARRANTIES
+OR CONDITIONS OF TITLE, NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS FOR
+A PARTICULAR PURPOSE. Each Recipient is solely responsible for
+determining the appropriateness of using and distributing the Program
+and assumes all risks associated with its exercise of rights under this
+Agreement , including but not limited to the risks and costs of program
+errors, compliance with applicable laws, damage to or loss of data,
+programs or equipment, and unavailability or interruption of operations.
+
+*6. DISCLAIMER OF LIABILITY*
+
+EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER RECIPIENT NOR
+ANY CONTRIBUTORS SHALL HAVE ANY LIABILITY FOR ANY DIRECT, INDIRECT,
+INCIDENTAL, SPECIAL, EXEMPLARY, OR CONSEQUENTIAL DAMAGES (INCLUDING
+WITHOUT LIMITATION LOST PROFITS), HOWEVER CAUSED AND ON ANY THEORY OF
+LIABILITY, WHETHER IN CONTRACT, STRICT LIABILITY, OR TORT (INCLUDING
+NEGLIGENCE OR OTHERWISE) ARISING IN ANY WAY OUT OF THE USE OR
+DISTRIBUTION OF THE PROGRAM OR THE EXERCISE OF ANY RIGHTS GRANTED
+HEREUNDER, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+*7. GENERAL*
+
+If any provision of this Agreement is invalid or unenforceable under
+applicable law, it shall not affect the validity or enforceability of
+the remainder of the terms of this Agreement, and without further action
+by the parties hereto, such provision shall be reformed to the minimum
+extent necessary to make such provision valid and enforceable.
+
+If Recipient institutes patent litigation against any entity (including
+a cross-claim or counterclaim in a lawsuit) alleging that the Program
+itself (excluding combinations of the Program with other software or
+hardware) infringes such Recipient's patent(s), then such Recipient's
+rights granted under Section 2(b) shall terminate as of the date such
+litigation is filed.
+
+All Recipient's rights under this Agreement shall terminate if it fails
+to comply with any of the material terms or conditions of this Agreement
+and does not cure such failure in a reasonable period of time after
+becoming aware of such noncompliance. If all Recipient's rights under
+this Agreement terminate, Recipient agrees to cease use and distribution
+of the Program as soon as reasonably practicable. However, Recipient's
+obligations under this Agreement and any licenses granted by Recipient
+relating to the Program shall continue and survive.
+
+Everyone is permitted to copy and distribute copies of this Agreement,
+but in order to avoid inconsistency the Agreement is copyrighted and may
+only be modified in the following manner. The Agreement Steward reserves
+the right to publish new versions (including revisions) of this
+Agreement from time to time. No one other than the Agreement Steward has
+the right to modify this Agreement. The Eclipse Foundation is the
+initial Agreement Steward. The Eclipse Foundation may assign the
+responsibility to serve as the Agreement Steward to a suitable separate
+entity. Each new version of the Agreement will be given a distinguishing
+version number. The Program (including Contributions) may always be
+distributed subject to the version of the Agreement under which it was
+received. In addition, after a new version of the Agreement is
+published, Contributor may elect to distribute the Program (including
+its Contributions) under the new version. Except as expressly stated in
+Sections 2(a) and 2(b) above, Recipient receives no rights or licenses
+to the intellectual property of any Contributor under this Agreement,
+whether expressly, by implication, estoppel or otherwise. All rights in
+the Program not expressly granted under this Agreement are reserved.
+
+This Agreement is governed by the laws of the State of New York and the
+intellectual property laws of the United States of America. No party to
+this Agreement will bring a legal action under this Agreement more than
+one year after the cause of action arose. Each party waives its rights
+to a jury trial in any resulting litigation.

+WINDOWBUILDER PROPERTY SHEET LIBRARY
+-------------------------------------
+
+This project is a fork of a subset of the WindowBuilder Eclipse
+plugin: http://www.eclipse.org/windowbuilder/
+
+Specifically, it contains the subset of WindowBuilder related to the
+propertysheet, intended for reuse in AOSP by the ADT plugin.
+
+The fork was modified as follows:
+* Started with revision 424 from the trunk:
+  http://dev.eclipse.org/svnroot/tools/org.eclipse.windowbuilder/trunk
+
+* Extracted the property package from org.eclipse.wb.core:
+   src/org/eclipse/wb/internal/core/model/property
+  and then everything it transitively references.  This turns out to
+  be a lot. I then started pruning out references to code we don't
+  need, such as support for editing Java constructs such as enums, or
+  dealing with a Java code model, etc.  This means some of the files
+  have been edited to remove methods and fields. For example, the
+  property category code was modified to no longer support the
+  persistent storage of categories.
+
+* The WindowBuilder code depended on a number of Apache Commons
+  libraries such as collections, lang, etc. Since ADT already uses
+  Guava, which provides a lot of the same functionality, I replaced
+  all the Commons calls with Guava calls in order to avoid having to
+  make ADT depend on (and load at runtime) the Commons libraries.
+
+* Finally, the propertysheet code was made into a library instead of a
+  plugin, such that it can be loaded into the ADT plugin.  This meant
+  mostly rewriting the DesignerPlugin class. It has kept its name
+  (since a lot of code references it for logging, resource loading
+  etc), but it is no longer an actual plugin. Instead it has init and
+  dispose methods for use by the AdtPlugin, and for logging it
+  delegates to the ADT plugin, etc.
+
+* Icons were moved into the DesignerPlugin package such that the
+  resource loading code could use a relative path, since with an
+  absolute path it would be looking in the embedding plugin's
+  resources.
+
+* To be consistent with the ADT codebase, I converted the files from
+  \r\n to \n newlines. Other than that, all formatting was left
+  unmodified.
+
+* Removed unused resources such as unreferences colors from
+  IColorConstants, unneeded messages from ModelMessages, and so on.
+
+* Note also that this Eclipse project is using a modified version of
+  the standard ADT Eclipse compiler settings: methods overriding other
+  methods and interfaces *without* using an @Override annotation are
+  ignored, since they were not using @Override annotations in the
+  WindowBuilder source base.
+  
+
+ADT ENHANCEMENTS
+------------------
+* I also modified the propertysheet in a few ways to add features
+  needed by ADT. These are all bracketed in the codebase with
+   // BEGIN ADT MODIFICATIONS
+   ...
+   // END ADT MODIFICATIONS
+
+  Specifically, I made the property table able to expand all and
+  collapse all. Properties have sorting priorities, and have separate
+  name and title attributes (and tooltips show the property name
+  rather than the title.) Text property editors allow field completion
+  by providing IContentProposalProvider (and optionally
+  ILabelProvider) instances via their getAdapter method. And the
+  property table will color values differently based on whether the
+  property is modified. (This allows us to draw default attributes
+  differently). Finally, the propertysheet now supports "expand by
+  default" (and for certain categories to be excluded, such as
+  deprecations).
+
+
+UPDATES
+--------
+
+We should keep an eye on the propertysheet code in WindowBuilder and
+migrate bug fixes and feature enhancements. To do that, first check
+out revision 424 from
+http://dev.eclipse.org/svnroot/tools/org.eclipse.windowbuilder/trunk
+That's the same baseline that this fork was based on.
+You can limit the checkout to just the org.eclipse.wb.core tree.
+
+Then check out the newest revision of WindowBuilder in a separate
+directory.
+
+Now diff the two trees. Look for diffs in the packages related to the
+propertysheet; this is going to be the packages that are present in
+this library.  If any of the diffs are related to the propertysheet or
+supporting code, apply them to this library, and then update this
+document to contain the new baseline revision (use 'svnversion .' to
+get the number).  Note that the diffs may need some rewriting if they
+reference Apache Commons code.
+
+Note that the ComponentsPropertiesPage.java class which is the main
+window in WindowBuilder is not used in our implementation; we instead
+have the PropertySheetPage class in ADT, so changes in that class

+ * <li>The setters on GridDataFactory all return "this", allowing them to be chained</li>
+ * <li>GridDataFactory uses vector setters (it accepts Points), making it easy to set X and Y values
