Sometimes two expressions produce identical results. You can indicate the
exact equivalence of two forms with the @equiv{} command.
The @equiv{} command is displayed as `==' in Info and
as `==' in the printed output.
Thus,
@lisp
(make-sparse-keymap) @equiv{} (list 'keymap)
@end lisp
produces
(make-sparse-keymap) == (list 'keymap)
This indicates that evaluating (make-sparse-keymap) produces
identical results to evaluating (list 'keymap).
