Right, we can now see the need for creating and keeping a proper source
repository. It seems stupid that the "real" lcd code we have now is in the ui
simulator, in Alan's code at home and in Gary's code at home. And they are
all mailed around in various archives...

Have you kept to your initial buffer-approach that draws everything in the
buffer and then writes the complete thing to the lcd in lcd_update()?

If you have, the ui simulator is gonna work pretty much unmodified with your
new code.

Good job! Can we get the windows simulator added to CVS too? We could
possible make the uisimulator in two directories, one for X and one for
Windows. I don't think there's any point to put them in the same dir, as they
won't really share any code. AFAICS.

I thought about toying up a filesystem api and simulate that (until we have a
real file system), then we could even start fiddling around with file lists
and directory hiearchies etc.
