#
#   This is a framework that allows a standard shell script
#   to be executed by simply typing "make".  The script must
#   be named "Makefile" or "makefile", so your make binary
#   will find it.
#
#   Note:  If your script needs to read something from the
#   terminal, you have to redirect from /dev/tty (see the
#   example below).  That's because stdin is the script itself.
#
#   Tested with BSD make (pmake) and GNU make (gmake).
#   Does NOT work with Solaris make and other dumb makes.

all:
	@sed '1,/^\.ifdef/d' Makefile | sh

ifdef notdef:foo	# For gmake (GNU).
.ifdef notdef		# For make / pmake (BSD).
