 40.1 Loading Readline Support
 =============================
 
 The module is not loaded by default and so has to be loaded and
 activated explicitly.  This is done with two simple lines of code:
 
      (use-modules (ice-9 readline))
      (activate-readline)
 
    The first line will load the necessary code, and the second will
 activate readline's features for the REPL.  If you plan to use this
 module often, you should save these to lines to your `.guile' personal
 startup file.
 
    You will notice that the REPL's behaviour changes a bit when you have
 loaded the readline module.  For example, when you press Enter before
 typing in the closing parentheses of a list, you will see the
 "continuation" prompt, three dots: `...'  This gives you a nice visual
 feedback when trying to match parentheses.  To make this even easier,
 "bouncing parentheses" are implemented.  That means that when you type
 in a closing parentheses, the cursor will jump to the corresponding
 opening parenthesis for a short time, making it trivial to make them
 match.
 
    Once the readline module is activated, all lines entered
 interactively will be stored in a history and can be recalled later
 using the cursor-up and -down keys.  Readline also understands the
 Emacs keys for navigating through the command line and history.
 
    When you quit your Guile session by evaluating `(quit)' or pressing
 Ctrl-D, the history will be saved to the file `.guile_history' and read
 in when you start Guile for the next time.  Thus you can start a new
 Guile session and still have the (probably long-winded) definition
 expressions available.
