+;;
+;; This package provides a TCP/IP stream emulation for GNU Emacs. If
+;; the function `open-network-stream' is not defined in Emacs, but
+;; your operating system has a capability of network stream
+;; connection, this tcp package can be used for communicating with
+;; NNTP server.
+;;
+;; The tcp package runs inferior process which actually does the role
+;; of `open-network-stream'.  The program `tcp' provided with this
+;; package can be used for such purpose.  Before loading the package,
+;; compile `tcp.c' and install it as `tcp' in a directory in the emacs
+;; search path. If you modify `tcp.c', please send diffs to the author
+;; of GNUS.  I'll include some of them in the next releases.
