这两天根据微软的这篇文章（Walkthrough: Approaches to Building a Visual Studio .NET 2003 Add-in Project that Enables HTML Tidy ）做了这个插件的安装包。
下面是一些介绍，估计都能看懂，就不翻译了，呵呵，比较懒！
Introduction to TIDY
When editing HTML it's easy to make mistakes. Wouldn't it be nice if there was a simple way to fix these mistakes automatically and tidy up sloppy editing into nicely layed out markup? Well now there is! Dave Raggett's HTML TIDY is a free utility for doing just that. It also works great on the atrociously hard to read markup generated by specialized HTML editors and conversion tools, and can help you identify where you need to pay further attention on making your pages more accessible to people with disabilities.
Tidy is able to fix up a wide range of problems and to bring to your attention things that you need to work on yourself. Each item found is listed with the line number and column so that you can see where the problem lies in your markup. Tidy won't generate a cleaned up version when there are problems that it can't be sure of how to handle. These are logged as "errors" rather than "warnings".
Dave Raggett has now passed the baton for maintaining Tidy to a group of volunteers working together as part of the open source community at Source Forge. The source code continues to be available under an open source license, and you are encouraged to pass on bug reports and enhancement requests at http://tidy.sourceforge.net/.
挺实用的。有兴趣的可以研究下。

补记：觉得VS.NET2003中的插件技术功能有限，不想在深入的去看。刚装了vs.net2005 web develper express ,感觉太爽了，而且明确提出支持XHTML，所以就没有必要再用这个插件了。其实早就有了安装文件，但是考虑到初学，。NET1.1还没有研究的怎么样的，就去看2.0，是不是有点提前了，还有就是现在做开发的话，还不能用处于BETA阶段的2005。呵呵，但是现在我们可以用它来做页面 ：）

PS:发现这个东西用的地方还真不少,在TopStyle里面有,在MindManger(管理你的头脑,很有用)里面竟然也用到了!!
"If you never do any planning, writing, research, organizing, learning or thinking, then you can probably manage without it. But for the rest of us, MindManager is a must-have product."
