	SFTP is a different protocol, a real one, and while still in a 
draft, will hopefully become an RFC some day. It's rather a file system 
protocol now. See this:

	http://tools.ietf.org/wg/secsh/draft-ietf-secsh-filexfer/

	in contrast to that, SCP is just an RCP over SSH link. Very simple, 
not extensible, meant to be a quick replacement for rcp(1).

	if sftp(1) command can do all what scp(1) can do then users could 
stop using scp completely, and preferrably just link it to sftp.
