This is a gem of the Devver fork of Octopi (a Github API library), which can be found at http://github.com/fcoury/octopi. This gem exists solely to enable us to use patches which have not (yet) been rolled into the official Octopi gem. You should almost certainly use the official Octopi gem instead of this one.
Gemfile gem 'devver-octopi', '~> 0.2.14'
