Cool, that's really ok.

The problem is a bit more complicated for us, actually.

The fact is that we are doing a wrong thing: when running in Centipede, 
we get the jars that match the project names.

So if a project needs ant.jar, in the Centipede-enhanced descriptor one 

  <depend project="ant" version="1.5"/>

*If* the Gump project was named "ant", all could work, since the version 
tag would be ignored and the jar has the same name of the project.

The fact is, as you know, that

  1 - there can be more than one jar per project
  2 - projects distribute jars with names that not only are
      different from the project name, but are also with different naming

What is needed is a system where you ask for a project and a version, 
and you get back a set of jars. We want it to be mirror-aware too.

This means maintaining a metadata repository that contains all these 
infos. I was thinking that Gump could keep such a metadata repository.

I imagine that for every project name there is a directory that contains 
as many files as the releases, named as the release versions themselves.
The system just needs to get that file and scan it for the actual names.
It would not point to a URL, but to a meta-url that defines a mirroring 
scheme. For example:

  http://url/to/jar       ' no mirroring
  ftp://url/to/jar       ' no mirroring

For apache mirroring we just need to modify the closer.cgi script to 
give us a text or xml representation of the mirror locations.
