Scons (http://www.scons.org/) is used as the building tool.  Running 'scons'
from this directory will make: gsim -- gui simulator, sim -- text based
simulator, cmdparse/mapparse/rand -- tests.  OpenGL and FOX 1.0
(http://www.fox-toolkit.org/) are required for the GUI.

The simulators are run as 'sim <antfile> <worldfile>' and only performs antfile
versus itself.  The GUI is controlled by the keyboard: 'n' increments the time
by 1 step, 'm' increments by 100 steps.

Under 'ant-gen/' the pseudo-assembler can be compiled with 'javac Labeler.java'
and run with 'java Labeler [Labelled ant file] > x.ant'.  The script 'mkant' in
the same directory will do this 'mkant x' will produce the file '../x.ant'.
