If you'd like to evaluate CAB before installing it, or you simply want the documents (for example, if you want to read them in a machine without Visual Studio .NET installed), check the donwload section in the Community Site here: http://www.gotdotnet.com/codegallery/releases/viewuploads.aspx?id=22f72167-af95-44ce-a6ca-f2eafbf2653c 

Some days ago, we published a zip file containing just the docs (not the reference though) in complied HTML format.

Many of you have sent us feedback about this, and we listen!
