[[!tag obnam-wishlist]]


It would be nice for Obnam to have a tool to answer the question 
"how much space will be freed if I remove these generations?"

  - need to find list of chunks that are used only by the specified gens
  - perhaps also count B-tree reduction? cound nodes that are unshared by
    the relevant trees, or only shared by the trees to be deleted
  - however, the B-trees are going to be a fraction (a few percent) of
    the size of the chunk data, so they're not really worth it
