I feared it might take four.

Six and a half hours later, I didn't do as much as I would have liked, but I made it through everything major (including finding a bunch of broken stuff where I had to recompile some c code because the system's libraries had been updated at some point).

http://www.erif.org/ now has a template borrowed from the OSWD. I took this opportunity to reorganize the top menu from around 15 options to 5, massaging the subnavs appropriately.

And yeah, I know the content needs some TLC as well... but at least I'm not entirely ashamed of the layout anymore.
