#	Common Makefile for WWW Servers and some Gateways
#	-------------------------------------------------
#
# A Makefile in a subdirectory for the machine in question contains
# the necessary definitions of directories etc.
#
#	(c) CERN 1990, 1991 -- see Copyright.html for conditions
#
# This file should be invariant between systems.
#	DEPENDENCIES NOT COMPLETE @@
#
#	make		Compile and link the daemon (private version)
#	make install	Copy it into the system (implies make)
#	make update	Copy installed version into installed version
#	make uninstall	Unlink installed version from the system
#	make clean	Remove intermediate files
#	make cleanall	Remove intremediate files and products
#
#	make httpd	as make
#	make tigate	Make Techinfo gateway
#
#  NOTE: To make the WAIS gateway you need a ui.a library from the WAIS
#  distribution.
#	
# Macros required to be defined already for make:
#
# CC		The C compiler
# CFLAGS2	Flags for $(CC)
# LFLAGS	Flags for ld
# WWW		Root of WWW source tree
