OPTIONS FOR split
-----------------
--annotate=<annotation>::
This option is only valid for the split command.
-
- When generating synthetic history, add <annotation> as a
- prefix to each commit message. Since we're creating new
- commits with the same commit message, but possibly
- different content, from the original commits, this can help
- to differentiate them and avoid confusion.
-
- Whenever you split, you need to use the same
- <annotation>, or else you don't have a guarantee that
- the new re-created history will be identical to the old
- one. That will prevent merging from working correctly.
- git subtree tries to make it work anyway, particularly
- if you use --rejoin, but it may not always be effective.

+Whenever you split, you need to use the same <annotation>, or else you
+don't have a guarantee that the new re-created history will be identical
+to the old one. That will prevent merging from working correctly. git
+subtree tries to make it work anyway, particularly if you use --rejoin,
+but it may not always be effective.
-b <branch>::
--branch=<branch>::
This option is only valid for the split command.
-
- After generating the synthetic history, create a new
- branch called <branch> that contains the new history.
- This is suitable for immediate pushing upstream.
- <branch> must not already exist.

This option is only valid for the split command.

- If you use '--rejoin', git subtree attempts to optimize
- its history reconstruction to generate only the new
- commits since the last '--rejoin'. '--ignore-join'
- disables this behaviour, forcing it to regenerate the
- entire history. In a large project, this can take a

--onto=<onto>::
This option is only valid for the split command.
-
- If your subtree was originally imported using something
- other than git subtree, its history may not match what
- git subtree is expecting. In that case, you can specify
- the commit id <onto> that corresponds to the first

- into your project, and git subtree will attempt to build
- its history from there.

- If you used 'git subtree add', you should never need

--rejoin::
This option is only valid for the split command.
-
- After splitting, merge the newly created synthetic
- history back into your main project. That way, future
- splits can search only the part of history that has
- been added since the most recent --rejoin.
-
- If your split commits end up merged into the upstream
- subproject, and then you want to get the latest upstream
- version, this will allow git's merge algorithm to more
- intelligently avoid conflicts (since it knows these
- synthetic commits are already part of the upstream
- repository).
-
- Unfortunately, using this option results in 'git log'
- showing an extra copy of every new commit that was
- created (the original, and the synthetic one).
-
- If you do all your merges with '--squash', don't use
- '--rejoin' when you split, because you don't want the
- subproject's history to be part of your project anyway.
