OK, it looks like my program is working, now that I've had time and Perl
books available...

OK then, I think the correct way to treat it is with the following list of
acceptable changes:

CRITICAL -> *
* -> CRITICAL
* -> UNKNOWN
UNKNOWN -> ALIVE
UNKNOWN -> CRITICAL

I'm unsure about this last one...  thoughts?

GNU Go is both players...  that's what's so weird.  I'm using a modified
version of the twogtp_a script to play them against each other, btw.  I
didn't change the playing logic.

I'll post a copy of my script as soon as I fix the network on my laptop
