I just recently wrote an autoplayer to play games between Stobor and Crafty (which 
is too buggy on an HP workstation to finish a single game) and between Stobor and 
Zarkov. I first create a pipe, then I run the other program with fork() and 
exec(), and then I use dup2() to switch stdin and stdout around. So far it works 
great.

BTW, remember to close the child program *before* breaking the pipe. :)

Cheers,
Tom
