Subverting your homedir is an article covering setting up, managing, and using subversion for your home directory. It’s based on a similar article published a couple years ago describing in detail how to manage your home directory with CVS. This just adds the extra goodness that Subversion provides.
The benefits for those who go through the settup work are 1) a complete history of all changes to your personal files, configuration settup, and documents, 2) Multiple redundant backups of your data, 3) Access to all (or just part) of your personal settings/documentation from anywhere there is an internet connection, 4) Automatic configuration for any machine you have access to, 5) and The ability to delete files at any time from any location your using your SVN home settup (because the files are never really gone forever… they are just “retired” to SVN.)
