That is sort of the question I was implying previously (when mentioning adding meta data), as to whether or not there is a "protocol" or if the two format just coincidentally share a part of a common structure. >>> We can try to add some support for other local-VCS afterwards, but it >>> shouldn't be a priority. >> So you would say that the support for other VCS should be removed? > > Not necessarily removed, but considered second class for now.

I would prefer that to avoid a strict Git dependency.
