you use 'tbpath=dir1;dir2;dir3;etc' as an option.

also you can get by with 6 gigs.  All the files are now compressed using
Eugene's compression format, and they total to about 5.9 gigs.  You can
use them _without_ decompressing them if you use crafty v16.5 and later.

download the TB/tbgen.zip file from my ftp machine.  Unzip it somewhere
and start reading.  It has a file named (I think) probe.txt that explains
what you have to do...
