| SAX API finalized
| SAX implementation finalized
| SAX test suite checked in

I've thought about it and decided that I can do all of these within
two weeks.  If it takes more than a couple of days to fix my monitor I
will just physically remove the drive and mount it on my Linux box at
work to get hold of the files.

If someone else could do the SAX documentation I think that would be
useful as a combined test of common understanding and sanity check.
I can of course do it if nobody else can, but it might be better if
someone else does it.
