+*** Emacs can be compiled with libgnutls support
+This is the default.  You will then be able to use the functionality
+in gnutls.el, namely the `open-gnutls-stream' and `gnutls-negotiate'
+functions.  It's easiest to use these functions through
+`open-network-stream' because it can upgrade connections through
+STARTTLS opportunistically or use plain SSL, depending on your needs.
+
+Only versions 2.8.x and higher or GnuTLS have been tested.
+
+*** gnutls-log-level
+Set `gnutls-log-level' higher than 0 to get debug output.  1 is for
+important messages, 2 is for debug data, and higher numbers are as per
+the GnuTLS logging conventions.  The output is in *Messages*.
