/*
* 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.
