+;;; Create a stream for the given Unix file descriptor.
+;;;
+;;; If INPUT is non-NIL, allow input operations. If OUTPUT is non-nil,
+;;; allow output operations. If neither INPUT nor OUTPUT is specified,
+;;; default to allowing input.
+;;;
+;;; ELEMENT-TYPE indicates the element type to use (as for OPEN).
+;;;
+;;; BUFFERING indicates the kind of buffering to use.
+;;;
+;;; TIMEOUT (if true) is the number of seconds to wait for input. If
+;;; NIL (the default), then wait forever. When we time out, we signal
+;;; IO-TIMEOUT.
+;;;
+;;; FILE is the name of the file (will be returned by PATHNAME).
+;;;
+;;; NAME is used to identify the stream when printed.
