/**
 * The preverify MoJo runs the preverify command from the given J2ME SDK.
 * 
 * Preverification takes place in the phase process-classes, that means after
 * successfull compilation. The MoJo takes the classes to preverify from
 * ${project.build.outputDirectory} and places the preverified classes into the
 * same directory. Therefore no change to the packaging phase is neccessary.
