[Bug-XBoard] [bug #27687] [FR] fallback to GNU Chess if Fairymax not found

[Tim Mann]

Follow-up Comment #6, bug #27687 (project xboard):

I think this could be improved a lot within the package management systems. 
For instance, in ubuntu, I notice the xboard package does this:

Recommends: xfonts-75dpi | xfonts-100dpi
Suggests: gnuchess | phalanx, x-terminal-emulator

Unfortunately it seems the "suggests" line doesn't cause any suggestion to
actually be given to the user in most cases, or at least not where he will see
it.  But one could move the chess engines to "recommends", and then I think
they would get installed by default.

I think if they are separated by "|" the user will get prompted as to which
one(s) he wants instead of just getting them all.  I haven't checked that,
though.

Another idea is to have the chess engine packages do something like
"Provides: xboard-chess-engine" and have the xboard package require that. 
Then I'm pretty sure apt will make the user choose at least one to install.

The provides/requires thing should work with RPM too, I think.

I'm far from an expert on these packaging technologies, though, so the above
are just ideas to try, not something I'm sure will work out well.
