Each time you run this script, your current canvas config files will be backed up to
a git repo located at ${REPO_LOC}/${REPO_NAME}.  If the repo doesn't exist yet, it
will be created.  Each running of this script will result in a new commit to the repo
containing any changes to your config files from the last time you ran it.
