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. |
