Well I finally figured out how to create an installer package for xboard-mac
I decided against making it with the stable version as any version without the ability to save in a conf file's usefulness is severely limited, it think, and also one can contribute to the testing of new features
Instead I used the latest source from H.G. Muller's git repository. 20101002
It installs the master xboard.conf in the /etc/xboard folder
Put's the help files in /usr/local/share/info
and the fairymax ini's where they are suppose to be in /usr/share/games/fairymax
The main questionable thing is I put the xboard binary in the Applications/xboard/ folder with a folder for polyglot and a folder for Engines. Mostly because A) this is where a mac user would expect to find them. b) I tried installing the fairymax engine in the default location but xboard still wouldn't find it anyway and C) a normal mac user really wouldn't be able to get at that folder to see what engines are installed, what are their exact names and install more. So I decided this was simpler and made the master config point to fairymax's new location.
Includes polyglot several books, fairymax, gnuchess5.07.9b, crafty 23.0, fruit 2.2.1, fruit 3.2.1 and stockfish 1.6.2
Enjoy!
(have a new one up in a few hours)
