Getting Started with Ruby

MPXJ is available as a RubyGem, which can be installed using gem:

gem install mpxj

or included in you Gemfile and installed using bundler.

Note that the Ruby version of MPXJ is just a wrapper around the Java library, and provides read-only access to schedule data. You will need Java installed to make use of this Gem. You can find some documentation for the Gem here

You'll find a general introduction to MPXJ's functionality here.
