# this gist can be used to list all targets, or - more correctly - rules,
# that are defined in a Makefile (and possibly other included Makefiles)
# and is inspired by Jack Kelly's reply to a StackOverflow question:
#
#   http://stackoverflow.com/questions/3063507/list-goals-targets-in-gnu-make/3632592#3632592
#
# I also found this script - http://www.shelldorado.com/scripts/cmds/targets - which does
# something similar using awk, but it extracts targets from the "static" rules from a single
# Makefile, meaning it ignores any included Makefiles, as well as targets from "dynamic" rules
