This tutorial has two parts. The first shows you how to use CVS as a non-developer, i.e. how to get sources from CVS and keep them updated. The second part introduces you to using CVS as a developer, showing you how to modify, add and remove files on CVS and perform other developer-related tasks. If you are new to CVS, it's recommended that you begin in the first section and proceed to the second section; if you have some basic CVS experience but are going to be using CVS as a full-fledged developer for the first time, you should find everything you need in the second section, but you may want to go through the first section as a review.
