Add a help target to a Makefile that will allow all targets to be self documenting

Makefile

# Add the following 'help' target to your Makefile
# And add help text after each target name starting with '\#\#'
 
help:           ## Show this help.
	@fgrep -h "##" $(MAKEFILE_LIST) | fgrep -v fgrep | sed -e 's/\\$$//' | sed -e 's/##//'
 
# Everything below is an example
 
target00:       ## This message will show up when typing 'make help'
	@echo does nothing
 
target01:       ## This message will also show up when typing 'make help'
	@echo does something
 
# Remember that targets can have multiple entries (if your target specifications are very long, etc.)
target02:       ## This message will show up too!!!
target02: target00 target01
	@echo does even more

look the comments of the forked file! they make it look awesome ...
