On the macports mailing list, people were complaining that the old MacPorts guide isn't posted anywhere anymore (since OpenDarwin is gone, and it hasn't been set up by the folks running MacOS Forge - the new macports host - yet).
So, I whipped up a script checkout/update the guide's docbook XML from the macports repository and re-generate the html once a day.
It's a little out of date, but still contains some useful information. I imagine that the people interested in updating it will be a little more eager to do so now that it's posted somewhere where there changes can be read.
