 # This Makefile builds an mDNSResponder daemon and a libdns_sd.so shared library

 #
 # 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.

 # $@ 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"
