This is a workshop that I gave at the New Jersey Institute of Technology (NJIT) in the Spring of 2012 as part of the workshop series of the university's chapter of the Association for Computing Machinery (ACM). It was based on a similar tutorial I had given during meetings of NJIT ACM's SIG GNU/Linux in the Fall of 2011.
