ttrts - Tiny Terminal RTS v0.3.0

SYNOPSIS

ttrts MAPFILE

DESCRIPTION

ttrts is a tiny terminal based RTS where that uses text
files as order lists to control it's units

This means that any user, program or cat that can read
and write to text files can play the game

OPTIONS

MAPFILE - File to read in the initial game state from

USAGE

When invoked, ttrts will set up the game in a local 
directory called `ttrts_{GAME_NAME}`

The GAMESTATE files in this directory can be read and
interpreted by human, robot or cat. 

ttrts will then await ORDER files from each participant

Once all ORDER files have been received ttrts will 
calculate the turn and output a new GAMESTATE file

This process repeats until the game is over

TTRTS GAMEPLAY

RULES

The game takes place in a series of simultaneous turns
on an arbitrarily sized 2D board

Each turn, the client outputs a GAMESTATE file and 
waits for an ORDER file from each player

All commands are evaluated simultaneously with friendly
fire enabled by default

The game is over when any of three conditions are met -
* All remaining units are controlled by a single player
* No units are left (draw)
* All units left are unable to move (draw)

UNITS

Each unit occupies a single tile on the board, facing 
in a compass direction (NESW)

Units will only accept orders from their owner

Units can receive only a single order each turn

Units cannot occupy the same tile as other units/walls

ORDERS

F   - Move unit [F]orward one space, leaving a wall
     
This wall will remain until the end of the game, 
blocking movement to that tile

Movement orders have no effect if impossible, eg.
* Attempting to move outside of map
* Attempting to move on to tile occupied by unit/wall

L/R - Rotate unit [L]eft or [R]ight

Unit will rotate clockwise or counter-clockwise,
this order cannot fail

A   - [A]ttack in straight line in front of unit
      
Attack will continue forward until unit can't progress,
all units within the path of the attack are destroyed.
