# arch_spec_ace.mk
#
# Architecture/site specific makefile fragment
# for inclusion by packages that use ACE (the communications package).
#
# This should be included _after_ standard.mk.
#
# Created by Gordon Watts
#
# This file assumes that ACE_DIR points to the standard ACE distribution
# directory. This means that "ACE_DIR/ace" contains all the .h files you need.
# Also, ACE_DIR/ace contains the libraries with which one must link.
#
# Include paths will be setup so you you can do the following:
#	#include "ace/Synch.h"
# following the pattern of SRT.
