modifying the tarski theme

HI there! I asked a question at wordpress.com concerning the possibility to modify the tarski theme which I really dig (changing the wrapper for a wider layout) and finally figured out on my own how to do it. I wrote a brief tutorial and a member suggested I post it here. So here is the link to the how-to:

Who knows, maybe somebody will find it useful…
