This, xprez, is a graphical interface with TVP.  It uses and works with
Tcl75/Tk41, Tcl76/Tk42, and Tcl/Tk80, all under both UNIX and Win95.

Under UNIX, if xprez is properly installed, you should be able to run it
simply by typing ``xprez''.  Under Windows95, you will need to run it as
``xpwish xprez''.  Additionally, under Windows95, you may notice two bugs: 
1) When you exit, an invalid page fault is generated in CW3215.DLL, and 2) 
If you try to load/save, and then, at some future point, exit, you may not
be able to and if you try to Ctrl-Alt-Del and forcefully kill the process,
your disk may start spinning and you may need to reboot.  This does not
happen on all versions of Win95.  Fortunately, the program (same source)
is tested to work flawlessly under FreeBSD. 

I would like to believe that the program is reasonably intuitive.  Click
on the topmost card of a set to select that set.  The set should be raised
above your hand.  Click on the same card again to try and lay that set.
Click on the "Pass" button to pass.

If you wish to permanently change some of the options, such as the delay
between AI turns, or the "Click-On-Canvas" option, you should edit either
the compiled xprez file (it is a simple Tcl script), or the
xprez/xprez-proc-configure.in source file.  Search for "proc Customize".
You can change any of the values that are set inside of this proc.  Eg.
To turn off the "Click-On-Canvas" option by default, edit the xprez file,
search for "proc Customize", look for the line saying something about
"clicks between rounds", change the "1" to "0", and rerun the program.
