+ * tableinitcmtemplate.c - template for initialising lookup tables for
+ * translation from a colour map to true colour.
+ *
+ * This file shouldn't be compiled.  It is included multiple times by
+ * translate.c, each time with a different definition of the macro OUT.
+ * For each value of OUT, this file defines a function which allocates an
+ * appropriately sized lookup table and initialises it.
+ *
+ * I know this code isn't nice to read because of all the macros, but
+ * efficiency is important here.
