Core Wars Deluxe v1.3
-------------------------------------------------------------------------------

The displays that are available for use with this program include curses,
X-Windows, and also just ordinary text, if neither is available.  If your 
system does not have X-Windows support, then comment out the X-Windows lines
in the Makefile and uncomment the the Curses lines.  This should be the 
default in the distrubution package to begin with.  If you have X-Windows 
support, then you may take one of two possble routes.  If you want to have
just X-Windows support, and not the curses support, then uncomment the proper
line in the Makefile.  If you would like to have both available, there is 
another line for you to uncomment instead.  The advantage of both displays
being supported at the same time means that if you choose to play on some 
terminal that does not have graphical support, then the program will detect
this and automatically run the curses version.  This means that you will not
have to recompile the whole program to switch between one version to another.
For those people who sometimes operate on terminals that have neither curses
or X-Windows support, then there is an option in the configuration file that
will allow you to turn the display off and display summary reports instead.
To do this, just place the option "DISPLAY 0" in your configuration file.

If you use the X-Windows display, there is a maximum size of the core that
you will be allowed to use the display.  If this maximum is surpassed, then
either the program is aborted, or if the curses version is also available,
then the curses display is used instead.  I am planning, in the next version,
to make this more reasonable than just aborting the program.  I do believe
that the current maximum is somewhere in the 11,000 to 12,000 range for the
core size.

Also, if you use the X-Windows display, you may abort the current play at 
any time by pressing any key or clicking a mouse button.  Once the play is
over, the window will remain until one of the above has happen.

If anyone would like to contribute ports to other kinds of displays, I would
be more than happy to accept them.  What I would like for such a port is
a copy of displayer.c with your type of display added, the display function
(such as sdisplay.c for Suns) that contains the code for your type of display,
and the Makefile that allows you to select the compilation of your type of
display.  This type of interface makes it easier to add new displays and 
prevent modification to the actual program itself.  If you need to add header
files, then that is acceptable.  If the interface needs more paramaters, 
please consult me before changing any other functions elsewhere in the code
to do so.  I look forward to any display support that comes my way!
