This is my presentation for the event: "Building with Open Source: For Developers", and was presented today for the Trinidad and Tobago Computer Society Software Freedom Day events. Comments and questions are welcome. This work is licensed under a Creative Commons Attribution-Share Alike 3.0 Unported License. It is available in the OpenOffice format (naturally) and as a pdf. I apologize for not being able to finish the presentation on time. One hour is just too little to get me going on about Drupal.
