# Get cdn.rawgit.com hash URLs for most recent commit of files in git repo.
# 1) cd to root directory of repository
# 2) run script on one or more filenames.
# Your working dir must be repo root or the URLs will be wrong.
# If you have 'globstar' enabled and your shell supports it, run with ** for recursion.

Works in linux bash, windows 'gitbash' (mingw64), and I'd be surprised if it didn't work in OS X too.
