The aim is not to provide a full blown VCS, but a toolkit for doing certain functions: diff, patch, merge, in memory.

It grew out of a requirement I have for a cross-platform patch and merge utility, coupled with an idea for building an OO wrapper for Algorithm::Diff.

I was not aware of the VCS project on Sourceforge - I will check this out (pun intended) as I have an interest in VCS systems in general.
