<title > Variables loaded from config files</title>
<para >
Variables that are loaded from the config files are referenced by
enclosing them within hash marks (#), or with the smarty variable
<link
linkend="language.variables.smarty.config">$smarty.config</link> .
The second syntax is useful for embedding into quoted attribute
values.

<example >
<title > config variables</title>
<para >
foo.conf:
</para>
<programlisting >
< ![CDATA[
pageTitle = "This is mine"
bodyBgColor = "#eeeeee"
tableBorderSize = "3"
tableBgColor = "#bbbbbb"
rowBgColor = "#cccccc"

</programlisting>

<programlisting >
< ![CDATA[
{config_load file="foo.conf"}

<table border= "{#tableBorderSize#}" bgcolor= "{#tableBgColor#}" >
<tr bgcolor= "{#rowBgColor#}" >
<td > First</td>
