Subversion (SVN)
Subversion is a free/open source version control system. That is, Subversion manages files and directories, and the changes made to them, over time. This allows you to recover older versions of your data or examine the history of how your data changed. In this regard, many people think of a version control system as a sort of “time machine.” Subversion can help you archive old versions of files and directories, resurrect them, examine logs of how they've changed over time, collaborate with people on documents (usually over a network) and keep track of who made which changes.
Here's a tutorial on how to use Subversion for meta.openp2pdesign.org.
