Ahh, very good points! The ability to run multiple middlegen(s) from a smaller properties file is definately better than behomoth maven.xml files and the plugin would be definately is easier for users just getting started. If something like MEVENIDE gets up to speed (an Eclipse plugin for Maven), maven plugins like this would be even more valuable. -D
