 #
 # This is a generalized framework for converting between SCM
 # repository formats.
 #
 # In its current form, it's hardcoded to convert incrementally between
 # git and Mercurial.
 #
 # To use, you must first import the first git version into Mercurial,
 # and establish a mapping between the git commit hash and the hash in
 # Mercurial for that version. This mapping is kept in a simple text
 # file with lines like so:
 #
 # <git hash> <mercurial hash>
 #
 # To convert the rest of the repo, run:
 #
 # convert-repo <git-dir> <hg-dir> <mapfile>
 #
 # This updates the mapfile on each commit copied, so it can be
 # interrupted and can be run repeatedly to copy new commits.
