Mistelix A DVD authoring tool for GNU/Linux desktop systems 5th January 2009 Student: Jordi Mas i Hernàndez Tutor: Jordi Ceballos Villach This project is dedicated to the hundreds of free and open source hackers that invest their time in making all the infrastructure that made this project possible. I want also to thank to the UOC their flexibility given to me to develop a project that is based on Linux (instead of Windows), that runs of top of Mono (instead of Microsoft .Net), that is written in English and that its outputs are open source. 2/59 Table of contents 1.
