[Bioperl-l] GSoC/BioPerl Reorganization Project

We haven't talked much about the versioning yet, but it will be on the list
to figure out asap.
So far, the plan is to split out Bio::Root first, followed by a couple
modules that depend only on Bio::Root. The plan I proposed was Bio::Das,
Bio::Event then Bio::Location. Depending on how much time is remaining for
the GSoC project, the next to split out would be Bio::Factory and
Bio::Coordinate, because they depend on Bio::Root and Bio::Location. I plan
to still help with the reorganization after the internship is over, but I
obviously have to have a stopping point for the GSoC project.
Rob provide me with a really nice scrip to list dependencies of the modules,
so I plan to make a roadmap towards to end of the summer that will help
guide the rest of the reorganization. At that point, we'll have to deal with
the circular dependencies carefully.
This is a huge project, much bigger than I can do in one summer. But I plan
to get it started in a way that makes it easy for others to contribute.
