+/****
+* NAME
+*   netChat - network chat class
+*
+* DESCRIPTION
+*   This class adds support for 'chat' style protocols -
+*   where one side sends a 'command', and the other sends
+*   a response (examples would be the common internet
+*   protocols - smtp, nntp, ftp, etc..).
+*
+*   The handle_buffer_read() method looks at the input
+*   stream for the current 'terminator' (usually '\r\n'
+*   for single-line responses, '\r\n.\r\n' for multi-line
+*   output), calling found_terminator() on its receipt.
+*
+* EXAMPLE
+*   Say you build an nntp client using this class.
+*   At the start of the connection, you'll have
+*   terminator set to '\r\n', in order to process
+*   the single-line greeting.  Just before issuing a
+*   'LIST' command you'll set it to '\r\n.\r\n'.
+*   The output of the LIST command will be accumulated
+*   (using your own 'collect_incoming_data' method)
+*   up to the terminator, and then control will be
+*   returned to you - by calling your found_terminator()
+*
