<blockquote>
<p><b>Warning:</b> These customization variable names and meanings may change in any
Texinfo release. We always try to avoid incompatible changes, but we
cannot absolutely promise, since needs change over time.
</p></blockquote>
<p>Many aspects of the behavior and output of <code>texi2any</code> may be
modified by modifying so-called <em>customization variables</em>. These
fall into a few general categories:
</p>
<ul>
<li> Those associated with @-commands; for example,
<code>@documentlanguage</code>.
</li><li> Those associated with command-line options; for example, the
customization variable <code>SPLIT</code> is associated with the
<samp>--split</samp> command-line option, and <code>TEXINFO_OUTPUT_FORMAT</code>
allows specifying the output format.
</li><li> Those associated with customizing the HTML output.
</li><li> Other ad hoc variables.
</li></ul>
<p>Customization variables may set on the command line using
<code>--set-customization-variable '<var>var</var> <var>value</var>'</code> (quoting
the variable/value pair to the shell) or
<code>--set-customization-variable <var>var</var>=<var>value</var></code> (using
<code>=</code>). A special <var>value</var> is ‘<samp>undef</samp>’, which sets the
variable to this special “undefined” Perl value.
</p>
<p>The sections below give the details for each of these.
