I'm working on a CAS authentication piece for our Dspace repository.  I'm starting with the CAS plug-in patch from Paris-Dauphine University, extensively modified to suit our needs.  I've got the code working on our test instance, but I'd like to move it all into the modules directory so as to be able to maintain it more easily.  I've moved most of the source files into the xmlui module, and it works well -- but I'm not sure where to put the pom files:


Is it possible to maintain pom files as overlays?  If so, does anybody have any advice on where to put these files?  Or do I just have to keep track of them manually, as with the dspace.cfg file?

Any advice appreciated.
