Makefile

# Makefile for quartet
#
# This Makefile depends on a file called "Makefile.defs" which contains
# platform-specific definitions.
#
# To build quartet, first run "make depend" (which relies on g++ version 3.1 or
# higher) and then either "make" (equivalent to "make debug") or "make release".
#
# This is for GNU make; other versions of make may not run correctly.
