+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) 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. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+Introduction
+
+ The maven-antlr3-plugin will use the {{{http://www.antlr.org}ANTLR tool}}
+ to process grammars included in your project and generate code (typically
+ Java source code) during the generate-sources phase of the build.
+
+ The plugin doesn't expose all ANTLR features yet.

+Installation
+
+ The plugin has not been pushed to the official Maven repositories yet, so
+ you will need to add the maven-antlr3-plugin repository to your plugin
+ repositories list.  Add the following to your project's POM,
+
++-----+
+<project>
+  ...
+  <pluginRepositories>
+    <pluginRepository>
+      <id>bif-repository</id>
+      <url>http://maven.badgers-in-foil.co.uk/maven2/</url>
+    </pluginRepository>
+  </pluginRepositories>
+  ...
+</project>
++-----+
+
+
+Getting ANTLR v3
+
+ Until the appearence of ANTLR v3 in the Maven repositories you will need to
+ grab a snapshot and install into your local repository.  (NB although
+ there is an existing <<<org.antlr:antlr:3.0>>> artifact, this is actually
+ a beta version of ANTLR from several months before the final release -- do
+ not use it!)
+
+ Download the ANTLR 3 release from {{http://www.antlr.org/download.html}}
+
+ On unpacking the .tar.gz file, you should find <<<antlr-3.0.jar>>> and
+ <<<antlr-runtime-3.0.jar>>> files in the resulting <<<lib>>> subfolder.
+ These should be installed into your repository with the Maven
+ <<<install-file>>> command, using the POM metadata provided below.
+
+ For the tool jar,
+
++-----+
+mvn install:install-file -DgroupId=org.antlr -DartifactId=antlr-tool -Dversion=3.0 -Dpackaging=jar -DpomFile=tool.pom -Dfile=lib/antlr-3.0.jar 
++-----+
+
+ For the Java runtime jar,
+
++-----+
+mvn install:install-file -DgroupId=org.antlr -DartifactId=antlr-java-runtime -Dversion=3.0 -Dpackaging=jar -DpomFile=runtime.pom -Dfile=lib/antlr-runtime-3.0.jar

+Usage
+
+ To enable the plugin, add the following to you project's pom.xml,
+
++-----+
+<project>
+  ...
+  <build>
+    <plugins>
+      <plugin>
+        <groupId>uk.co.badgersinfoil.maven.plugins</groupId>
+        <artifactId>maven-antlr3-plugin</artifactId>
+        <executions>
+          <execution>
+            <goals>
+              <goal>antlr</goal>
+            </goals>
+          </execution>
+        </executions>
+      </plugin>
+    </plugins>
+  </build>
+  ...
+</project>
++-----+
+
+ You should place your ANTLRv3 grammar files in <<<src/main/antlr>>>, and
+ the plugin with scan the subfolders of this folder looking for grammar files
+ (names ending with '.g').
+
+ The generated files will automatically be included in the list of elements
+ to be built in the project's compile phase.
+
+* Alternative Filename Extensions
+
+ To use an extension other than .g for grammar files, use the <<<includes>>>
+ configuration element (remember to have an entry in this list for .g files
+ if you still want them to work as well),
+
++-----+
+      ...
+      <plugin>
+        <groupId>uk.co.badgersinfoil.maven.plugins</groupId>
+        <artifactId>maven-antlr3-plugin</artifactId>
+        ...
+        <configuration>
+          <includes>
+            <include>**/*.g</include>
+            <include>**/*.g3</include>
+          </includes>
+        </configuration>
+      </plugin>
+      ...
++-----+
+
+Compiling generated code
+
+ The generated code should just get compiled by running <<<mvn compile>>> etc.
+ but you will need to include the ANTLR runtime classes as a dependancy of
+ your project.  Add the following dependancy to your POM,
+
++-----+
+  ...
+  <dependency>
+    <groupId>org.antlr</groupId>
+    <artifactId>antlr-java-runtime</artifactId>
+    <packaging>jar</packaging>
+    <version>05-14-2007.17</version>
+  </dependency>
+  ...
++-----+
+
+ Ensure you add a dependancy on the Java runtime rather than on the ANTLR tool
+ artifact, or you will end up adding the transative dependancies on
+ StringTemplate and the old ANTLRv2 to your project, when all you need are the
+ runtime support classes.
