Building From Source
To make life easier, you can use Bundler with the included Gemfile to load all the necessary development dependencies.
For example, to install all the dependencies and run the test suite for the first time:
$ bundle install $ bundle exec rake test
Documentation
Documentation is written in Textile, and converted to HTML using Jekyll.
API reference is RDoc, converted to HTML using Yardoc.
