3 # Script to deltafy an entire GIT repository based on the commit list.
4 # The most recent version of a file is the reference and previous versions
5 # are made delta against the best earlier version available. And so on for
6 # successive versions going back in time. This way the delta overhead is
7 # pushed towards older version of any given file.
9 # NOTE: the "best earlier version" is not implemented in mkdelta yet
10 # and therefore only the next eariler version is used at this time.
12 # TODO: deltafy tree objects as well.
14 # The -d argument allows to provide a limit on the delta chain depth.
15 # If 0 is passed then everything is undeltafied.
