Subversion

To start a new project on R-Forge, I've had to starting coming to grips with Subversion, the widely used program for source code versioning. To help me, I've found this tutorial very helpful for learning the "Subversion lifecycle" and the general use of the program. The Subversion book is a wonderful resource, but I'm currently not yet at the stage where my knowledge of the thing is at the level required to understand it properly.
