sorts working copies into subdirs by GitHub org name

README.md

Given a directory full of working copies, like ~/projects, this script helps sort them into subdirectories based on org name. It inspects Git remote names and URLs to do so.

Currently doesn't handle forks very well, because git doesn't know what a fork is.

NOTE TO SELF: Hub is helpful. Use hub clone and hub fork --remote-name=origin rather than clicking the big green "Fork" button, as this sets up origin/upstream remotes properly.
