Ben Meyer (aka icefox) pointed out this quick tutorial on getting Subversion (SVN) up and running with Apache & SSL. The tutorial covers install with Debain, but is fairly relivant for any other distro.
SVN is a replacement for the venerable Current Versioning System (CVS) use to manage very large, very distributed, digital information. While it is most commonly used to manage software projects, it can also be used to manage documents, websites, or even personal home directories.
The tutorial is particularly interesting to me because I am changeing over from CVS to SVN for source control on KDE.
