#	@(#)Makefile 1.4 (Delft University of Technology) 03/08/93
#
# This Makefile requires the environment variable MACHINE to be set to the name
# of your hardware/software platform. For instance, in the csh type:
#
#         %  setenv MACHINE vax ; make install
#
# to compile the objects into objects/vax/*.o and install the PROGRAM in the
# directory INSTALLDIR/bin/vax/*
#
# This Makefile is carefully constructed so that you can even run several
# "make"s concurrently in the same source directory, as long as the $MACHINE
# environments are different.
