> The help system in maven (and any other program as well) is typically what you use if you can't remember the syntax for a given command. The syntax for the help plugin is, however no simpler than any other command, and I always find myself ending up with searching google for info on how to use the help system to find out how to use, for instance, the dependency plugin. 
> I have suggested a new goal "mvn help:help" in the help plugin to use for getting info on how to use the help system. The same info should be printed when a user types "mvn -help".
