/**
 * 
 * This class will add a {@link org.apache.maven.plugins.annotations.Mojo}
 * annotation wherever a {@link t3.plugin.annotations.Mojo} is found.

 * 

 * The annotation created is a duplicate.

 * 

 * It allows to have both annotations: one is the standard Maven one (used by
 * Maven core and to generate Maven site for instance), the other is a copy with
 * a RUNTIME retention policy.
 * 
 *
 * 
 * This class will also add a call to "super.initStandalonePOM()" method at the
 * beginning of "execute()" method of the Mojo.
