I'm pretty sure I can do this.

Right - it builds on top of it that fit that pattern.

No, we can read from any number of sources, nothing has to be XML.
Like what you are saying - we just need to end up with a Maven POM in
Java (where you need to end up with your Gump object model).

All I'm saying is that both Maven and Gump shouldn't have to implement
the same mechanism to read all the formats gump digests (and as Maven
pulls dependencies, it will need to get that information). If Gump
intends to do this, all it needs to do is output a file from the gump
object model and Maven can read just one format (and if it outputs a
POM, even better :)

Of course, Maven *could* do all this, but either that's doubling up,
or putting Maven at the centre of Gump, neither of which seem
desirable :)

Will do.

Yep. See you there!
