   1 /*
   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.
   7  *
   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.
