Awesome.  And for those of us simple folk who like it when even the
basic instructions are explicit (especially in a tutorial, hint):

1) Put Gary's code in a file - call it, say, "daemon".

2) Run it via Guile, in the background, in one xterm ("the Guile
   window") so you can watch what will happen: 

        guile -s daemon &

3) In another terminal window ("the telnet window"), type:

        telnet YOURHOSTNAME 20004

   (Replacing YOURHOSTNAME with the host name of your workstation.)

4) You should see:

        Incoming connection from nnn.nnn.nnn.nnn port nnnn

   in the Guile window, and:

        Trying nnn.nnn.nnn.nnn ...
        Connected to YOURHOSTNAME.
        Escape character is '^]'.

   in the telnet window.

5) In the telnet window, type something:

        asdf

   You should see:
        
        asdf

   in the Guile window, and:

        you sent:
        asdf

   in the terminal window.

6) Disconnect from the telnet session by typing Control-rightbrace ^]
   then typing "quit" at the telnet prompt.

7) Run the 'jobs' Unix command to find the job number of the guile
   process, and kill it with the Unix 'kill' command.
