 its source repository, you can simply run `git repack -a` to copy all
 objects from the source repository into a pack in the cloned repository.

        If the reference repository is on the local machine,
        automatically setup `.git/objects/info/alternates` to
        obtain objects from the reference repository.  Using
        an already existing repository as an alternate will
        require fewer objects to be copied from the repository
        being cloned, reducing network and local storage costs.

 `--dissociate` option.
