#!/bin/bash
#
# 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
#
# TODO: does it still?
# This requires url aliases to be setup for the git-clone to work properly:
#
# [url "git@github.com:"]
# insteadOf = "gh:"
# insteadOf = "https://github.com/"
# pushInsteadOf = "github:"
# pushInsteadOf = "git://github.com/"
