/**
* This plugin generates an SqlMapConfig file containing sqlMap entries for
* all generated SQL maps. This demonstrates hooking into the code
* generation lifecycle and generating additional XML files.
* <p>
* This plugin accepts three properties:
* <ul>
* <li><tt>fileName</tt> (optional) the name of the generated file. this
* defaults to "SqlMapConfig.xml" if not specified.</li>
* <li><tt>targetPackage</tt> (required) the name of the package where the file
* should be placed. Specified like "com.mycompany.sql".</li>
* <li><tt>targetProject</tt> (required) the name of the project where the file
* should be placed.</li>
* </ul>
*
* Note: targetPackage and targetProject follow the same rules as the
* targetPackage and targetProject values on the sqlMapGenerator configuration
* element.
