* *
* Crafty is the "son" (direct descendent) of Cray Blitz. it is designed *
* totally around the bit-board data structure for reasons of speed of ex- *
* ecution, ease of adding new knowledge, and a *significantly* cleaner *
* overall design. it is written totally in ANSI C with some few UNIX system *
* calls required for I/O, etc. *
* *
* main() is the driver for the chess program. its primary function is to *
* cycle between asking the user for a move and calling for a tree search *
* to produce a move for the program. after accepting an input string from *
* the user, this string is first passed to Option() which checks to see if *
* it is a command to the program. if Option() returns a non-zero result, *
* the input was a command and was executed, otherwise the input should be *
* passed to input() for conversion to the internal move format. *

Does this copyright mean Crafty cannot be redistributed by the usual
Debian CD redistributors? Well, I asked Prof. Hyatt this exact
question via e-mail. The conversation was as follows:

no... I simply don't want someone to market crafty as a chess program.
Including it with something else is fine, knowing that there will be
newer (and better) versions for free on my ftp machine anyway. I put
that restriction in because there was a company that was making waves
about "Crafty is just too strong to be free, we are going to modify it
a little and then sell it..."
