is suitable for export as a separate git repository.

After splitting successfully, a single commit id is
printed to stdout. This corresponds to the HEAD of the
newly created tree, which you can manipulate however you
want.

Repeated splits of exactly the same history are
guaranteed to be identical (i.e. to produce the same
commit ids). Because of this, if you add new commits
and then re-split, the new commits will be attached as
commits on top of the history you generated last time,
so 'git merge' and friends will work as expected.

OPTIONS

--squash::
This option is only valid for add, merge, push and pull
commands.

Instead of merging the entire history from the subtree
project, produce only a single commit that contains all
the differences you want to merge, and then merge that
new commit into your project.

Using this option helps to reduce log clutter. People
rarely want to see every change that happened between
v1.0 and v1.1 of the library they're using, since none of the
interim versions were ever included in their application.

Using '--squash' also helps avoid problems when the same
subproject is included multiple times in the same
project, or is removed and then re-added. In such a
case, it doesn't make sense to combine the histories
anyway, since it's unclear which part of the history
belongs to which subtree.

Furthermore, with '--squash', you can switch back and
forth between different versions of a subtree, rather
than strictly forward. 'git subtree merge --squash'
always adjusts the subtree to match the exactly
specified commit, even if getting to that commit would
require undoing some changes that were added earlier.

Whether or not you use '--squash', changes made in your
local repository remain intact and can be later split
and send upstream to the subproject.

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.

--ignore-joins::
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
long time.

--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
revision of the subproject's history that was imported
into your project, and git subtree will attempt to build
its history from there.

If you used 'git subtree add', you should never need
this option.

--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.
