48	+	* is the short name of the holodeck file, appropriate for window naming, etc.
49	+	* The second and third arguments are the file descriptor numbers assigned to
50	+	* the server's standard output and input, respectively.  The stdin and stdout
51	+	* of the display process are used for normal communication with the server,
52	+	* and are connected to pipes going each way.  It is entirely appropriate
53	+	* for the display process to borrow the server's stdin and stdout for reading
54	+	* and writing user commands from the following list.  If the standard input
55	+	* is not available for reading, then a descriptor of -1 will be passed.
56	+	* The standard output will always be available for writing, though it
57	+	* may go to /dev/null.
