There is a file "book.lrn" that it updates as it learns (it also updates
book.bin, but this is non-portable) and which can be given to others.  If
someone sends you a "book.lrn" file, all you need to do is this:

rename book.lrn to something else (I will call mine learn.dat)
start crafty and type "import learn.dat".  It will read in that
file and pretend that it plays each game, and will update its own
book.bin and book.lrn files...

There is a learn.dat on my ftp site that is fairly current.  Just download
it and import at and you'll make your program think that it has played tens
of thousands of games and learned from them...
