xvier is a simple game where you and your opponent alternately throw
stones into free columns. The stones pile up in the columns, and the
goal is to get four stones in a row, in a column or diagonally. The
game compiles without modifications at least on

	Sun Sun4		SunOS 4.0, 4.1.1
	Sun Sun3/60		SunOS 4.0
	IBM RS6000		AIX 3.1
	HP 9000/720		HP-UX 8.05
	HP 9000/350		HP-UX 8.00
	DEC VS3100		Ultrix-32 V3.1
	DEC DS5400		Ultrix 4.2
	Sequent Symmetry	Dynix 3.0.17.9

To install xvier:

1. If you use Makefile.std, copy it to Makefile and choose locations
   for the X11-binary (default: /usr/local/bin), the game program
   (default: /usr/local/lib), and the manual page (default:
   /usr/local/man/man6).
   If you use imake, type "xmkmf" and "make depend".

2. Type "make".

3. Test the game with "./xvier -prog ./xvier_prog"

4. If it works, type "make install" (and "make install.man" with
   imake).

If you have problems with the compilation, look at the comments in
Makefile.std or Imakefile.

The game program uses a simple search tree, and the levels correspond
to the depth of this tree. Thus the higher levels are quite slow, but
normally I don't need them to get a good opponent ;-)
It's interesting that level 1 seems to be weaker than level 0.

Have fun!
