Am pretty impressed with the way you people have created TBB and documented it.
While going through this page: http://www.threadingbuildingblocks.org/files/documentation/index.html, I felt a bit uncomfy due to a lack of two things on the page.
1. A search box.
2. Detailed explanation in the documentation about what the functions do and why they do it that way (it's a bit of a pain to have to keep switching from the documentation page to the various tutorial pdf's you've provided)
Maybe I don't know about why you didn't provide it, but hoping that it could be made available for the sake of anyone who would find it useful.
But overall, great work and a super-responsive community!
