Publish your data with ERB and markdown
I will show you how to write a powerful and flexible publishing system by combining the power of ruby templates (ERB) and Markdown standard syntax in just 50 lines of code. The idea is to store your data in simple text files thanks to Markdown and use a template engine to present them in the format you want.

WebRI, RDoc Seuss
WebRI 1.2 is now up on the RubyGems.org servers. WebRI is a smart front-end for RDoc that provides a large selection of generators/templates for your documenting pleasure.

Big thanks to Володя Колесников for SDoc which I used as a study guide for getting my head around hacking RDoc. (It also explains the existence of the blackfish template).
