Bad news. The server hosting The Ruby Toolbox went bust on the evening of June 7th. While I do have backups, the
original source code is in a very outdated state so I currently don't feel it makes sense to try and get it running again.
For the time being, here is a very stripped down version of the Ruby Toolbox's contents.
A static site generator. Provides dozens of templating languages (Haml, Sass, Compass, Slim, CoffeeScript, and more). Makes minification, compression, cache busting, Yaml data (and more) an easy part of your development cycle.
