new target to display options

[Oliver Lehmann]

Hi,

here is a sample Makefile:



OPTIONS=	WITH_LALA:lala: \
		WITH_GAGAAA:ga ga ga:

options:
	@echo ${OPTIONS} | awk ' \
		BEGIN {\
			FS="[:]";\
			print "You may use the following build options:";\
		}\
		{\
			for(i=1;i<NF;i+=2) {\
				printf("%20s:\t%s\n",$$(i),$$(i+1));\
			}\
		}'


just type "make options" and relax ;)

  Greetings, Oliver
