<h2>Description</h2>

<p>VARREGEX defines the Perl regular expression matching
<a href="../rcvars.html">resource variables</a>.  The regex should
define a back reference that contains the name of the resource
variable and its arguments surround by parentheses.
</p>
<table border=0 cellpadding=4>
<tr valign=top>
<td><strong><font color="red">WARNING</font></strong></td>
<td><p><b>DO NOT MESS WITH THIS RESOURCE UNLESS YOU KNOW WHAT YOU ARE
DOING</b>.  If not set properly, page output can become munged.
One symptom of a bad VARREGEX setting is the occurrence of numerous
'<tt>$</tt>' characters in generated pages.  Make sure to test
your VARREGEX setting before using it with production archives.

<h2>Default Setting</h2>

<pre>
\$([^\$]*)\$
</pre>

<!-- *************************************************************** -->
<hr>
<h2>Resource Variables</h2>

<p>N/A
</p>

<!-- *************************************************************** -->
<hr>
<h2>Examples</h2>

<p>The following does a more stricter match:
</p>
<pre>
\$([^(\$]+(?:\([^)]+\))?)\$
</pre>
<p>Although slower than the default, it minimizes potential conflicts
in resource files encoded in multi-byte character sets like SJIS.
