If I want to print a markdown file from GitHub as it appears on screen, for example: https://github.com/RestKit/RestKit/blob/master/Docs/Object%20Mapping.md
Then how can
clone the repo
gem install bluecloth
http://deveiate.org/projects/BlueCloth
you can find examples of the api here: http://deveiate.org/projects/BlueCloth/browser/spec/bluecloth_spec.rb
