The above file is now available via git://pike-git.lysator.liu.se/pcvs2git.git/
Note: Requires rcs (and git).
Note that the tool is by no means finished, but it seems to generate an acceptable git archive from the repositories that I've tested with.
Caveat emptor: I've not tested with any repositories larger than the Pike 0.5 repository yet (~7000 file revisions).
