Backup adds instant version control to any file on
a Unix system. It is a lightweight interface to
the Subversion svn_fs library. It uses the
powerful version control software as a backend to
a simple and minimalistic (though effective) user
interface. It is designed for use on Linux/Unix
systems as a method of archiving configuration
files that change semi-frequently, but do not
necessarily warrant their own version control
mechanism or repository.
