# Makefile for fuzzing
#
# Use go-fuzz and needs the tools installed. For each fuzz.go in a plugin's directory
# you can start the fuzzing with: make -f Makefile.fuzz <plugin>
# e.g.
#
# 	make -f Makefile.fuzz proxy
#
# Each plugin that wants to join the fuzzing fray only needs to add a fuzz.go that calls
# the plugins's ServeDNS and used the plugin/pkg/fuzz for the Do function.
#
