Package This is a GUI tool written in C# for creating help files (.chm and .hxs with full text search and keyword search) from the content obtained from the MSDN/TechNet library via the MSDN Content Service. Package This allows you to generate personalized ebooks of MSDN or TechNet library content by allowing you to select the content you want from the TOC, build a help file, and use the content offline. 

We now have an updated version of Package This with community content support. Cheers.
