Subject Re: Newbie trying to understand how to use some plugins

Is this a problem that an installer solves in a much more flexible way?

Clearly assembly and shade can do a lot but sometimes it appears that 
linking to an existing installer with a Maven plug-in (izpack for 
example) might do it in a more simple and flexible way and allow a lot 
more pieces to be pulled in.
