/*
 * nullgame.c [FIXME]: Template defining the null game (in which no
 * moves are permitted and nothing is ever drawn). This file exists
 * solely as a basis for constructing new game definitions - it
 * helps to have something which will compile from the word go and
 * merely doesn't _do_ very much yet.
 * 
 * Parts labelled FIXME actually want _removing_ (e.g. the dummy
 * field in each of the required data structures, and this entire
 * comment itself) when converting this source file into one
 * describing a real game.
