Printing Notation
-----------------
Many of the examples in this manual print text when they are
evaluated. If you execute example code in a Lisp Interaction buffer
(such as the buffer `*scratch*'), the printed text is inserted into the
buffer. If you execute the example by other means (such as by
evaluating the function `eval-region'), the printed text is displayed
in the echo area.
Examples in this manual indicate printed text with `-|',
irrespective of where that text goes. The value returned by evaluating
the form (here `bar') follows on a separate line.
(progn (print 'foo) (print 'bar))
-| foo
-| bar
=> bar
