This is handy tool to reformat your ruby codes outside of your editor.
The only drawback is it only prints out the result and doesn't
overwrite the original source. As a workaround you can do these steps.
rbeautify bad_file.rb > good_file.rb; mv good_file.rb bad_file.rb
If you use sublime text, you can add this plugin instead. I'm using
it and it works great.
Hopefully these tools will eliminate the indentation issues we've
been seeing with the git pull requests.
