# This Makefile builds an mDNSResponder daemon and a libmdns.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 libmdns.
#
# Notes:
# $@ means "The file name of the target of the rule"
# $< means "The name of the first prerequisite"
# $+ means "The names of all the prerequisites, with spaces between them, exactly as given"
