Ant Wars World Files
--------------------

Ant Wars map files are a simple text file format.  The first three 
lines are newline terminated strings which respectively name the map, the
author, and the date of the map's creation.

The next two lines specify the map width and height in cells.  

The remaining lines describe the world itself.  Each line is 2*width
characters wide.  Even lines (including the first, 0 based line) start
immediately with a cell description character.  Odd lines begin with a space
and then the cell description character.  In this way the cells are
staggered as they will be in the game itself.  See the original ICFP manual
for more information.

The possible cell description characters are:

# -> Rock
@ -> Water
- -> Black Ant Hill
+ -> Red Ant Hill
1,2,3,4,5 -> One, two, three, four, or five food pellets on grass
. -> Grass



Apart from the addition of the mapname, author, and date fields, this format
is identical to the original ICFP format.  The other difference is the
addition of the 'water' cell.  Water is described in the Formicidae VM
description, but essentially, water is fatal to an ant.  Upon stepping in,
the ant dies and turns into food as usual.  Food on water will float in a
random direction once every 14 ticks until it reaches shore.
