You can change bundle format with the -t/--type option. See
:hg:`help bundlespec` for documentation on this format. By default,
the most appropriate format is used and compression defaults to
bzip2.

The bundle file can then be transferred using conventional means
and applied to another repository with the unbundle or pull
command. This is useful when direct push and pull are not
available or when exporting an entire repository is undesirable.

Applying bundles preserves all changeset contents including
permissions, copy/rename information, and revision history.

Returns 0 on success, 1 if no changes found.
