This command should be used on local archives (or mirrors) only. It is
763
quite slow on remote archives.
765
reuse_history allows you to specify any previous imports you
766
have done of different archives, which this archive has branches
767
tagged from. This will dramatically reduce the time to convert
768
the archive as it will not have to convert the history already
769
converted in that other branch.
771
If you specify prefixes, only branches whose names start with that prefix
772
will be imported. Skipped branches will be listed, so you can import any
773
branches you missed by accident. Here's an example of doing a partial
