I've just uploaded the completed tutoroial topic on OS access. It covers most of the common questions asked on this list about determining file access, launching programs (including use of the new subprocess module), accessing environment variables etc. It also has a short intro to bitmask manipulation and bitwise operators.
I've also updated the zip, tgz and pdf files too. For those interested in printing out the PDF (someone asked me recently) it currently runs to 342 pages of A4 but the margins are set so it should work fine on US Letter paper too.
