File README.openSUSE of Package crafty

crafty can use a startup file in the users HOME for its configuration, which is
~/.craftyrc. Likewise, it can use a subdirectory in the users HOME to store its
data. This can be ~/.crafty/ but it is configurable.

So, if your want to customize crafty to your needs you can do the following:

Copy the file /etc/crafty.rc to ~/.craftyrc and modify it according to the
comments inside the file. The endgame tablebase lookup is enabled. If you don't
like that, just remove the "egtb" line.

Similarly, a ~/.crafty/ directory can be created. Then copy the opening books
book.bin, bookc.bin and books.bin from /usr/share/crafty/ to ~/.crafty/.

The opening books and endgame tablebases that come with this package are
fairly basic. To make full use of crafty's capabilities you should get
larger versions from crafty's site (ftp://ftp.cis.uab.edu/pub/hyatt or
http://www.cis.uab.edu/hyatt/crafty/).
Please have a look at the documentation on how to do this.
