Module Name:

    listmung.c

Abstract:

    This is the main module for a stubfile generation utility

Author:

    Sanford Staab (sanfords) 22-Apr-1992
    11/15/94 Sanofrds: rewrote and expanded - but its not quite right yet.
             since this took me a day to do, I'm leaving it here in case
             anyone has to expand or alter it later - this version is
             easier to maintain.
