> - a few source control things (cvs2svn and py-rcparse consumers)

cvs2svn is used by libressl portable for the cvs to git conversion of
the openbsd repository. To my knowledge it's the only such tool that
understands cvs tags and converts them to git branches.

Its main deficit of randomly reordering simultaneous commits (i.e., same
second) is not a big deal for this repo. It happened once in the past
year.
