check the git status of many repos together

#!/bin/bash

# a script to check the git status of many repos together

# based on: https://gist.github.com/aroberts/3018100

# You can add something like this to your .profile/.bashrc to make it convenient to call this from anywhere
#         alias allgit='path-to-project/dev-setup/project-git-repos-status.sh'
