`@format' and `@smallformat'
============================
The `@format' command is similar to `@example' except that, in the
printed manual, `@format' does not select the fixed-width font and does
not narrow the margins.
This is an example of text written between an `@format' command
and an `@end format' command. As you can see
from this example,
the `@format' command does not fill the text.
Texinfo also provides a command `@smallformat', which is like
`@format' but uses a smaller font in `@smallbook' format. Note:small.
