`@lisp': Marking a Lisp Example
===============================
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' 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.(1) (Note:lisp-Footnote-1)
Mark the end of `@lisp' with `@end lisp' on a line by itself.
