<p>Texinfo has commands for indicating just what kind of object a piece
of text refers to.  For example, email addresses are marked by
<code>@email</code>; that way, the result can be a live link to send email
when the output format supports it.  If the email address was simply
marked as &ldquo;print in a typewriter font&rdquo;, that would not be possible.
