Attached is a Microsoft Word document containing the documentation for the tfpt.exe power toy commands, including screenshots.
[UPDATE 8/9/2007] I fixed the broken link to the power tools page.
[UPDATE 9/9/2006] TFPT is now available as a separate download (you no longer have to download the massive VS SDK). You can download from http://go.microsoft.com/?linkid=5422499 and find more details in this post. The installation package also contains an updated Word document that covers all of the commands and features in TFPT.
