Boost 101?

Good day to everyone, I have been monitoring boost for quite some time now, as well as stealing bits and pieces here and there. Now I want to actually start using it "as intended", on several UNIX platforms and CYGWIN. Some of those environments do not have a lot of disk space (web presence accounts). So, where would I find a small, but to-the-point tutorial, explaining the directory organization, library interdependence, etc., so that I can get the libraries I want and skip the bulky unnecessary stuff (for my projects, that is)? Any help is greatly appreciated. Leo.
