/**
 * This is an Ant task that will run the generator. The following is a sample
 * Ant script that shows how to run the generator from Ant:
 * 
 *  *  <project default="genfiles" basedir=".">
 *    <property name="generated.source.dir" value="${basedir}" />
 *    <target name="genfiles" description="Generate the files">
 *      <taskdef name="mbgenerator"
 *               classname="org.mybatis.generator.ant.GeneratorAntTask"
 *               classpath="mybatis-generator-core-x.x.x.jar" />
 *      <mbgenerator overwrite="true" configfile="generatorConfig.xml" verbose="false" >
 *        <propertyset>
 *          <propertyref name="generated.source.dir"/>
 *        </propertyset>
 *      </mbgenerator>
 *    </target>
 *  </project>
 * 
 * 
 * The task requires that the attribute "configFile" be set to an existing XML
 * configuration file.
 * 
 * The task supports these optional attributes:
 * 

 * "overwrite" - if true, then existing Java files will be overwritten. if
 * false (default), then existing Java files will be untouched and the generator
 * will write new Java files with a unique name
 * "verbose" - if true, then the generator will log progress messages to the
 * Ant log. Default is false
 * "contextIds" - a comma delimited list of contaxtIds to use for this run
 * "fullyQualifiedTableNames" - a comma delimited list of fully qualified
 * table names to use for this run
 * 
 *
