# Author:	Perette Barella
# Purpose:	This script generates a Makefile for a directory in a
#		Web page development hiearchy.  It generates a list of
#		directories which are recursed into by 'build',
#		and a list of files which are to be compiled in the
#		current directory.  The 'makedep.m4' macro package is
#		used to find dependencies with the .web files.
# Options:	-r - recurse into subdirectories.  makemake runs itself
#		     on all lower directories.
