Very cool. One more question, though. I'm not very adept with git and trying to wrap my head around how I might incorporate your solution into my current setup.

So I have a ~/git_repos directory for cloned modules from github where I keep perl modules that I contribute patches to. These repos track the upstream module and my own forked copy of the module. I also have a ~/perl/modules directory where I keep all my locally developed modules. These modules get installed to my local machine and they also get pushed out to cpan and github from this directory. This is where I modify my $PERL5LIB as appropriate to load the module from either ~/git_repos or ~/perl/modules.

Do you have any suggestions for how I might be able manage these repos connected to github and still use your solution?
