diagrams for your rails apps

Note: The RichText blog has moved to www.ricroberts.com

RailRoad lets you generate diagrams of your rails app.

Documentation often gets left to get out of date. With a tool such as this, you can just keep changing the code, automatically generating diagrams along the way.

The link above tells you how to set up a rake task to do just this, meaning that you'll never have to look at a redundant diagram again (or manually update one either)!
