# this script looks for a set of repos and reacts based on their availability
# if the git repo isn't located where it looks, it will clone it.
# if the git repo exists, it will pull it.
# "may this script be a light for you, in dark times" - Lady of the Lightppd

# WOULD BE NICE
## pass github username and specific repos to clone/pull
#
## break dependence on hard links and base path variables on assumptions
