Lenz Grimmer's RPM mini-HOWTO

A while ago I remember reading a post noting that Lenz Grimmer of SuSE had developed a mini-HOWTO on converting .tgz files to .rpm files consistent with the SuSE conventions. I've looked on his web page at SuSE (http://www.suse.de/~grimmer) and also at his section on the FTP site, but haven't found anything resembling what I'm looking for. Any pointers? Paul
