* Files structure

  The Ant plugin consists in two files. If you want to create a <<<touch>>> plugin, you must have:

  * <<<src/main/scripts/touch.mojos.xml>>>: contains Mojo(s) descriptor informations,

  * <<<src/main/scripts/touch.build.xml>>>: contains the Ant xml to execute.

** Ant Mojos descriptor

%{snippet|id=ant-mojo|url=http://svn.apache.org/repos/asf/maven/plugin-tools/trunk/maven-plugin-plugin/src/it/ant-basic/src/main/scripts/touch.mojos.xml}

** Ant script

%{snippet|id=ant-build|url=http://svn.apache.org/repos/asf/maven/plugin-tools/trunk/maven-plugin-plugin/src/it/ant-basic/src/main/scripts/touch.build.xml}
