Hi,
some applications need to divert a file in two parts.
One should contain all lines matching any patterns, the other
one all lines not matching any of the patterns.
So I want following flags:

	- d	divert the file
		"matches" to stdout
		"nomatches" to stderr
	-r	exchange stdout and stderr, if -d is given  

Will you post Your new grep to the net ? (I hope so)

Thanks in Advance for a nice new tool
