	echo "Example:"
	echo "    genpro src/conf codegen"

	echo "    The second line of each pair specifies the value (1002 in"
	echo "    the above example). Notice: hexadecimal is assumed, only"
	echo "    lower-case with four digits is allowed, and starts at 1000."

	echo " * You have to maintain org.zkoss.mesg.MessageConst.java"
