You could start with sections 1.5, 1.6 and chapter 2 of the NCO User's Guide: http://nco.sourceforge.net/nco.html#Introduction There's also a forum where you can look at the archived questions and answers as well as ask new questions. That's where we would end up forwarding any NCO questions, because we aren't the NCO developers and don't use it enough to be able to provide support.
