这里列出的小工具大部分都可通过我们上面提到过的扩展库找到，所以它们很容易安装。

Most of the gadgets listed here are available through the Extensions Gallery we covered previously, so they are easy to install.

如果您发现样本库的某个小工具看起来很有趣，那么通过点击查看详情页面，然后找到详情页面上的XML安装程序链接（见图7-2）。

If you find a gadget that looks interesting, click through to its page for details, then look for the Installer XML link on that page, as shown in Figure 7-2.

并非所有的小工具，都能通过扩展库安装或手动安装。

Not all gadgets are available to install as extensions through the extensions Gallery or manually.
