Re: [Duplicity-talk] [PATCH 0/2] consume a chain of sigtar files in rdiffdir delta mode

[T. Prost]

I just notice that rdiffdir is already on my system, although I never
installed it intentionally. Thus I assumed dependencies - however could
not find packages which are actually using rdiffdir ???:-|
But how are the actual dependencies really between the packages
discussed here and rdiffdir ?
