Python script to create a remote git repo that checks out the latest commit with a post-receive hook

create_repo.py

#
# This script creates a repository and sets it up with a post receive
# hook that checks out the code to the desired directory.
#
# Really nice for setting up an easy way to push code to a remote
# server without lots of overhead.
#
# After running this script simply add a remote locally like
#   
#   git remote add web ssh://you@server/path/to/repo.git
#
# Then pushing to the remote is as easy as
#
#   git push web
