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