       [ xterm options ] [ host [ arguments ] ]
	-nodo	no execute, just print the command that would execute
	-R	run the xterm on the remote host (default local)
	-N	title and iconname the xterm window with the given title
	-rsh	use rsh to login to the remote host (default $cmd)
	-ssh	use ssh to login to the remote host
	-telnet	use telnet to login to the remote host
	-std	equivalent to "-telnet -name xterm-std -N ''"
The default host is the local host.  A host beginning with a : is taken
to be a command which outputs the hostname.  Any final arguments are
passed to the remote login program.  Unless a -N option with a non-null
title or a -name xterm option is given, the xterm window is titled and
iconnamed with the hostname.  Use -N DEFAULT to use xterm's default title
and iconname.  Use -N with a null title to explicitly use the hostname
as the title and iconname.
