# To use this create a directory that you want to use for git repos, e.g. $HOME/git and copy/symlink this script into it.
# Then you can use it like this:
#
# ./clone github.com/robertgzr/dotfiles
# ./clone https://bitbucket.org/foo/bar
#
# If you don't have gitconfig set up like I have (using aliases for github/bitbucket ssh access) this won't really work
