Some other notes about editing scenario information:
(just use a text editor to edit the ascii file to include
this stuff before using shuffle)

TERRAIN
=-=-=-=
No terrain editor yet, but here are the various types of terrain:
T01-T18         various single trees, but not all work in all the
                different climates
SPLIT2, SPLIT3  the blossom trees. They start as normal trees and
                change to b. trees after a while, regenerating the
                tiberium around them
TC01-TC05       clumps of trees (impassible); not all types work in
                all climates (I think)
ROCK1-ROCK7     various large rocks (not the same as those in the
                overlay section). Not all work with all the climates.
Terrain has the format:
cell#=type, None
(actually, None is probably used to associate it with a trigger, but I
haven't seen it used yet).

Remember, when adding stuff, you need a \r\n (carriage return and newline)
after each entry. Look at the file with a hex editor to understand a bit
better. There is an additional \r\n at the end of each section.

SMUDGE
=-=-=-
Puts burn marks on the ground.
SC??            don't know the full range of them.
Format seems to be:
cell#=type,cell#,None
(again, None is probably a trigger. Don't know why the cell# is repeated,
but I haven't seen a smudge with different cell values).
