Yes, you're right: I didn't have any TMG files with beavers when I
programmed it.

The format for the moves in the TMG files is something like:

  X Y ZZZZZZZZZZZZZZZZZ

where X is the move number (positive for player 0 and negative for
player 1), Y is the move type (I'll return to that), and ZZZZZ is a
string with information about the move.

Examples are:

  -1 1 43:

for player 2 rolling 43 in the first move.

  -1 4 13/9 24/21

for player 2 moving 13/9 and 24/21 etc etc.

Here is my incomplete list over the move types:

Move type       Description
 1              Roll
 2              Auto double
 3              ???
 4              Move
 5              Double
 6              ???
 7              Take
 8              Beaver
 9              ????
10              Pass
11              ???
12              ???
13              ???
14              Win single
15              Win gammon
16              Win backgammon
17              out of time
18              ???
19              Table stake information

As you see there are few unknowns. Until now move type 8 was
also unknown :-)

I've programmed gnubg to crash if it reads one of these files, in the
hope that the poor user will mail us. Not a pretty solution I admit :-)

I've fixed that as well.

I've fixed some of the problem: in the other imports we freeze the GUI
while loading the match, and waiting with the update until the match has
finished loading. That should make the import somewhat faster.
