commit-patch - 2.6-2.1 main

Normally version control systems don't allow fine grained
commits. commit-patch allows the user to control exactly what gets
committed by letting the user supply a patch to be committed rather than
using the files in the current working directory.
.
commit-patch supports Darcs, Git, Mercurial, Bazaar, Monotone, Subversion,
or CVS repositories.
.
Also included is an Emacs interface to commit-patch. It allows you to just
hit C-c C-c in any patch buffer to apply and commit only the changes
indicated by the patch, regardless of the changes in your working
directory.
