<h3 class="section">3.2 Texinfo File Header</h3>
<p><a name="index-Header-for-Texinfo-files-159"></a><a name="index-Texinfo-file-header-160"></a>
Texinfo files start with at least three lines that provide Info and
TeX with necessary information. These are the <code>\input texinfo</code>
line, the <code>@settitle</code> line, and the <code>@setfilename</code> line.
<p>Also, if you want to format just part of the Texinfo file, you must
write the <code>@settitle</code> and <code>@setfilename</code> lines between
start-of-header and end-of-header lines. The start- and end-of-header
lines are optional, but they do no harm, so you might as well always
include them.
<p>Any command that affects document formatting as a whole makes sense to
include in the header. <code>@synindex</code> (see <a href="synindex.html#synindex">synindex</a>), for
instance, is another command often included in the header. See <a href="GNU-Sample-Texts.html#GNU-Sample-Texts">GNU Sample Texts</a>, for complete sample texts.
<p>Thus, the beginning of a Texinfo file generally looks like this:
<pre class="example"> \input texinfo @c -*-texinfo-*-
@c %**start of header
@setfilename sample.info
@settitle Sample Manual 1.0
@c %**end of header
</pre>

<li><a accesskey="2" href="Start-of-Header.html#Start-of-Header">Start of Header</a>: Formatting a region requires this.
