<span id="index-Start-of-header-line"></span>
<p>A start-of-header line is a Texinfo comment that looks like this:
</p>
<div class="example">
<pre class="example">@c %**start of header
</pre></div>
<p>Write the start-of-header line on the second line of a Texinfo file.
Follow the start-of-header line with an <code>@settitle</code> line and,
optionally, with other commands that globally affect the document
formatting, such as <code>@synindex</code> or <code>@footnotestyle</code>; and
then by an end-of-header line (see <a href="End-of-Header.html">End of Header</a>).
</p>
<p>The start- and end-of-header lines allow you to format only part of a
Texinfo file for Info or printing. See <a href="texinfo_002dformat-commands.html"><code>texinfo-format</code> commands</a>.
</p>
<p>The odd string of characters, ‘<samp>%**</samp>’, is to ensure that no other
comment is accidentally taken for a start-of-header line. You can
change it if you wish by setting the <code>tex-start-of-header</code> and/or
<code>tex-end-of-header</code> Emacs variables. See <a href="Texinfo-Mode-Printing.html">Texinfo Mode Printing</a>.
