# IMPORTANT NOTE: This is a Makefile for *GNU make*

# If "make os=xxx" gives lots of errors like "Missing dependency operator",
# then try typing "gmake os=xxx" instead.
#
# This Makefile builds an mDNSResponder daemon and a libdns_sd.so shared library 
# for Linux. It also builds several example programs for embedded systems. 
#
# Make with no arguments to build all production targets.
# 'make DEBUG=1' to build debugging targets.
# 'make clean' or 'make clean DEBUG=1' to delete prod/debug objects & targets
# 'sudo make install [DEBUG=1]' to install mdnsd daemon and libdns_sd.
#
# Notes:
# $@ means "The file name of the target of the rule"
# $< means "The name of the first prerequisite"
# $* means "The stem with which an implicit rule matches"
# $+ means "The names of all the prerequisites, with spaces between them, exactly as given"
# For more magic automatic variables, see
