A wrapper around tarsnap which does two things:
* Lets you define "backup jobs" (tarsnap invocations) in a
config file, though on its own this has little advantage over just
using a a shell script.
* The ability to expire old backups using a Grandfather-father-son
backup scheme. This feature can be used in conjunction with
tarsnapper backup jobs, or standalone, to be applied to any existing
set of tarsnap backup archives, regardless of how they have been
created.
