Rails - Dec 2005 - Condensed Rails reference?

Guys,

I''ve read the Agile Guide, waded through the Rdocs, but still want for
more of a condensed reference, preferably in the form of a 5-10 page
cheatsheet.

Anyone aware of such a beast?

The Agile Guide is great, but is quite wordy when used as a reference for
quick lookups.

Thanks!

John
