v0.5.6
This mainly improves logging under Unix and adds the beginnings of a help page. I'm making this the official release and branch from now on, I'll update the web page later as time permits. There is an issue with the update.rdf that I haven't yet figured out, so for now you'll need to install it manually.
Jo, I've been unable to reproduce the problem with the siegel web page. Can you try it with the new version and send me the entire contents of the log file?
