Many thanks to 'theoffset' Ismael Cortés <leamsi.setroc AT gmail.com> 
for suggesting crafty to me and then helping to get everything 
working.
27 Jun 2006 stable release build crafyt-20.1afx-i486-5.tgz

Original sources obtained separately here:
ftp://ftp.cis.uab.edu/pub/hyatt/

For convenience I've combined the source code and common files
used by crafty into a single tarball: crafty-20.1afx.tar.bz2

The original source files are all in the Resources/pasture directory:
(crafty-20.1.zip, bitmaps.tgz, sound.zip, book.bin, bookc.bin,
books.bin crafty.doc.ascii, crafty.hlp and crafty.man)
at http://amigolinux.org.

As configured by default, this package should install under a
single directory, like /opt/chess since the the binary looks 
for the shared and config files in the same directory -even the log
and rc files.

With the help of <theoffset>, I got the -D defines working for a still
cleaner way to get this right, without patching any source files. Most
importantly the logfiles and rc files are in ~/ (your $HOME), and 
the common files under $PREFIX/share/crafty.

He also provided code for the xboard-crafty wrapper, which runs xboard
with crafty as the engine. xboard is also available from this site:
http://amigolinux.org

A small patch to the Makefile and chess.h would fix everything easier,
for compatibility with PkgBuild and for setting this up with sane Linux-style
installation paths. theoffset supplied the syntax for adding some of the
available DEFINES, making it possible to set the paths correctly.

However, the location for the speak executable is hard-coded 
into chess.h (line 1075) in such a way that the crafty executable looks for
the speak script in the same directory as itself. However, certain paths in 
the speak script may need to be adjusted to fit your system. So, instead of 
installing 'speak' as an executable in $PRE_FIX/bin, I copy it to the doc
directory as an example.
To use it, edit (soundpath) and copy it to the same directory as crafty.
Be sure and make it executable also (chmod 755 speak). This could be handled
the same way as building xboard-crafty, but the speak script is rather long
for another cat < EOF inclusion in the PkgBuild script.

This actually compiles and runs easily with 'make linux' with everything
running in the same directory. But under Linux we should at least have
the logfiles in a sane location. It seemed best to make all the dirs more
LFSH conformant. Getting this all into a nice conformant package has posed
nearly every possible difficulty.
