Comment (by pmetzger):

 It's not really that great a description, and in particular doesn't tell
 me what parts of what I did can be replaced with what -- things like the
 hack I needed to add to alter the version number to remove the "." still
 seem to be needed. In fact, it isn't clear what goes away other than the
 path for the distfile.

 If you want to get people to fix portfiles properly, it might be nice if
 someone (perhaps even you) wrote real docs. I'm also reluctant to make
 changes here when I don't know what I'm actually doing. If you do, could
 you supply your changes instead, or documentation?
