For help actually using E-Blah, you can go to
http://www.eblah.com and send a message to Martin. I know that he had developed something at one time, but I think it is rather old now...but we are planning to get something on the Wiki soon.
In the old documentation, we had a how to build your own theme guide, but I haven't converted it over to the Wiki yet, and it needs updating too. We are also working on a detailed explaination of everything inside of the template.css file guide...but again it isn't done:)
Check back on the Wiki over the next week or so, and hopefully we have something there.
