I use tortoise and
SVN for my version control on both
PostNuke and non-
PostNuke development. There is no explicit interface between
PN and
SVN, or any module that I know of. I'm intrigued in how you would integrate
PN with a source code management (SCM) system...
There are many valuable features in
PN but xoops and mambo also have many valuable features. You will need to evaluate each to see which is best for your particular situation.
