The script is only for map files, although I'm working on the savegames.

Civ2 maps, savegames and scenario files are all binary and, I assume, platform
dependant. I don't have a mac and a copy of civ2 to test this on. Plus I am
pulling out the terrain and river overlay by checking the high and low nybbles,
which is going to break (?) on a bigendian machine.

Good, cause that's what I did (and it seems to work).

Since these are only maps, I was mostly interested in the terrain. I figure I
can always edit the file afterwards to use different settings.
