>Description:
	The proposed patch would allow tee to be used to send data
	to TCP or UDP sockets, as well as to the already opened
	file-descriptors (such as 2) without resorting to hacks
	like /dev/stderr.

	There can be any number of these "files" specified, as long
	as they preceed the regular files on the command line.

	For example:

	tee -d 2 -t www.example.com 80 -u localhost 1081 log1.txt log2.txt

	The patch also modifies the usage() handling to exit with 0,
	when help was requested (-h), and with EX_USAGE otherwise.
