vadm is a simple svn-like command line tool for versioning unix system files, ownership and permission information. It uses subversion under the hood and maps all files that you decide to version into a single per-user repository. As a single adminstrator you can decide to selectively and non-intrusively version some files through your own home directory.
vadm is released under the terms of the GPL Version 2 or later and was written by Holger Krekel with initial contributions from Jens-Uwe Mager.
