 # pcmkversion correctly (using in-place modification).

	# $(3) ... final arguments determined with $2 (e.g., pacemaker.spec)
	#
	# Note that if $(3) is a specfile, extra case is taken so as to reflect
	# pcmkversion correctly (using in-place modification).
	#
	# Also note that both ways to specify long option with an argument
	# (i.e., what getopt and, importantly, rpm itself support) can be used:
