Before I reinvent the wheel, is there any tool (or module on which such a tool could be easily written) that has capabilities similar to sysf)?

Basically what sysf does is let you manage system files for multiple linux systems from a central repository, sharing files that are common and providing the ability to override files that differ. It supports some nice features such as the ability to diff the repository against the current configuration for a given machine, ability to archive current configuration, etc..

I've done some looking around on google and CPAN for something like this but have not found anything useful.
