@lisp

The @lisp command is used for Lisp code. It is synonymous with the @example command.

This is an example of text written between an
@lisp command and an @end lisp command.

Use @lisp instead of @example so as to preserve information regarding the nature of the example. This is useful, for example, if you write a function that evaluates only and all the Lisp code in a Texinfo file. Then you can use the Texinfo file as a Lisp library.(8)

Mark the end of @lisp with @end lisp on a line by itself.
