Variables that are loaded from the config files are referenced by enclosing
them within hash marks (#), or with the smarty variable $smarty.config.
The second syntax is useful for embedding into quoted attribute values.
配置文件中的变量需要通过用两个"#"或者是smarty的保留变量 $smarty.config.来调用（下节将讲到）
第二种语法在变量作为属性值并被引号括住的时候非常有用.
（译注：举个例子
{include file="#includefile#"} 这样#includefile#将被当作字符处理，而不表示配置文件变量，
但可以这样表示 {include file="`$smarty.config.includefile`"}不要忘了加``）
Example 4-5. config variables
例 4-5.从配置文件引用的变量
foo.conf:
pageTitle = "This is mine"
bodyBgColor = "#eeeeee"
tableBorderSize = "3"
tableBgColor = "#bbbbbb"
rowBgColor = "#cccccc"
index.tpl:
{config_load file="foo.conf"}
<html>
<title>{#pageTitle#}</title>
<body bgcolor="{#bodyBgColor#}">
<table border="{#tableBorderSize#}" bgcolor="{#tableBgColor#}">
<tr bgcolor="{#rowBgColor#}">
<td>First</td>
<td>Last</td>
<td>Address</td>
</tr>
</table>
</body>
</html>
index.tpl: (alternate syntax)
{config_load file="foo.conf"}
<html>
<title>{$smarty.config.pageTitle}</title>
<body bgcolor="{$smarty.config.bodyBgColor}">
<table border="{$smarty.config.tableBorderSize}" bgcolor="{$smarty.config.tableBgColor}">
<tr bgcolor="{$smarty.config.rowBgColor}">
<td>First</td>
<td>Last</td>
<td>Address</td>
</tr>
</table>
</body>
</html>
OUTPUT: (same for both examples)
<html>
<title>This is mine</title>
<body bgcolor="#eeeeee">
<table border="3" bgcolor="#bbbbbb">
<tr bgcolor="#cccccc">
<td>First</td>
<td>Last</td>
<td>Address</td>
</tr>
</table>
</body>
</html>

Config file variables cannot be used until after they are loaded in from a config
file. This procedure is explained later in this document under
{config_load}
.
配置文件的变量只有在它们被加载以后才能使用.
这个过程将在以后
{config_load}
. 的章节里说明.
