I want to use org-mode files in one of the many Ruby static website
generation tools (Webby, Webgen, Jekyll, etc.). Thus, I needed a way to
extract simple HTML from an org-mode file *without* relying on emacs.

Thus, org-ruby was born. It's not nearly as full featured as the emacs-based
HTML export, but at the moment I am successfully using org-mode files as
content for Webby <http://webby.rubyforge.org/>static websites.

Or you can just grab the gem and go:

sudo gem install org-ruby
