        Coff in all its varieties is implemented with a few common
        files and a number of implementation specific files. For

-       @file{coff-m88k.c}. This file @code{#include}s
-       @file{coff/m88k.h} which defines the external structure of the

-       defines the internal structure. @file{coff-m88k.c} also
