The intention of the script is to be an example of how things *could* be
done. Depending on how your setup is configured, you need to patch this
script anyway. For example: the REMOTE_USER environment variable must be
matched with how you authenticate in your webserver. Therefore I don't
see any value in trying to make the script as generic as possible. I
could, of course replace the "${prog}" with just gitolite if that's what
people prefer.
