I'm guessing these used to be in the plugin SDK, but they are no longer part of the community edition.
The VCS plugin I'm writing is pretty similar to p4, so seeing that source would be a big help.
Failing that, I would like to have the "local change lists" map to something in the VCS, which is OK, but I'd like to know:
a) how to use ChangeListManagerGate.moveChanges (and from where)
b) how to hook and/or prevent moving files between change lists (so I can move them in the vcs equivalent).
