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