<a name="index-HTML-cross-references"></a>
<a name="index-Cross-references_002c-in-HTML-output"></a>

<p>Cross references between Texinfo manuals in HTML format become, in the
end, a standard HTML <code>&lt;a&gt;</code> link, but the details are
unfortunately complex.  This section describes the algorithm used in
detail, so that Texinfo can cooperate with other programs, such as
<code>texi2html</code>, by writing mutually compatible HTML files.
</p>
<p>This algorithm may or may not be used for links <em>within</em> HTML
output for a Texinfo file.  Since no issues of compatibility arise in
such cases, we do not need to specify this.
</p>
<p>We try to support references to such &ldquo;external&rdquo; manuals in both
monolithic and split forms.  A <em>monolithic</em> (mono) manual is
entirely contained in one file, and a <em>split</em> manual has a file
for each node.  (See <a href="HTML-Splitting.html#HTML-Splitting">HTML Splitting</a>.)
</p>
<a name="index-Dumas_002c-Patrice-1"></a>
<p>The algorithm was primarily devised by Patrice Dumas in 2003&ndash;04.
