      在上面的文件之中，从<title>种玉堂</title>开始是你需要修改的地方，下面逐一指出各部分的含义与作用。

<title>种玉堂</title>
站点名称

<description>关于软件、关于硬件、关于站点制作、关于互联网上的点点滴滴……</description>
站点介绍

<site>http://gztw.com/</site>
网站地址

<search>http://gztw.com/lancms/mt-search.cgi?search={query}&IncludeBlogs=1</search>
站点搜索地址，当中{query}部分将是用户通过 Google Toolbar 输入的关键字将插入的位置

<send>http://gztw.com/lancms/mt-search.cgi?search={selection}&IncludeBlogs=1</send>
站点搜索地址，当中{selection}是用户在当前浏览器中选中文本并选择使用你的站点搜索时，所选中文本将插入的位置

<feed refresh-interval="3600">http://gztw.com/atom.xml</feed>
站点RSS文件的地址，当中3600是 Google Toolbar 自动更新的时间间隔，单位秒

<icon mode="base64" type="image/x-icon">AAABAAMAICAAAAEAIACoEAAANgAAABgYAAABACAAiAkAAN4QAAAQEAAAAQAgAGgEAABmGgAAKAAA……wz8AAMADAAD5lwAA8Z8AAPM/AAA=</icon>
Base64编码后的图标文件

      如何将你的站点图标进行Base64编码呢？你可以使用在线的编码工具，也可以使用另外一个笨办法，那就是将图标做为邮件的附件发送给自己，存储准备发送或收到之后，在查看邮件时选择查看邮件的原始信息，当中附件就会被编码成Base64，可以拷贝出来直接使用。另外，请注意 Google Toolbar 图标按钮支持24 bits 的 XP-style RGBA icons，所以你除了可以使用一般的站点图标（favicon.ico），也可以另外为 Google Toolbar 准备更高质量的图标。

      自定义按钮文件准备好之后，存储到你的站点上，然后在站点上做一个链接，例如<a href="http://toolbar.google.com/buttons/add?url=http://gztw.com/button.xml">将本站添加到你的Google Toolbar</a>，当使用Google Toolbar新板本的用户单击该链接，就能够将你站点自定义按钮添加到工具栏上，并可以通过该按钮快速访问你的站点，或者搜索你站点上的内容，还能够阅读你站点上的RSS频道内容，与你的站点紧密的结合在一起。
