    --1.14              A working-tree format that supports content filtering.
    --1.14-rich-root    A variant of 1.14 that supports rich-root data (needed
                        for bzr-svn and bzr-git).
    --2a                First format for bzr 2.0 series. Uses group-compress
                        storage. Provides rich roots which are a one-way
                        transition.
    --default           First format for bzr 2.0 series. Uses group-compress
                        storage. Provides rich roots which are a one-way
                        transition.
    --pack-0.92         New in 0.92: Pack-based format with data compatible
                        with dirstate-tags format repositories. Interoperates
                        with bzr repositories before 0.92 but cannot be read
                        by bzr < 0.92. Previously called knitpack-
                        experimental.  For more information, see http://doc
                        .bazaar-vcs.org/latest/developers/packrepo.html.

:Description:
  The check command or bzr developers may sometimes advise you to run
  this command. When the default format has changed you may also be warned
  during other operations to upgrade.
