 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.

 	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.

 --onto=<onto>::

-	If your subtree was originally imported using something
-	other than git subtree, its history may not match what

 --rejoin::
 	This option is only valid for the split command.
-
-	After splitting, merge the newly created synthetic

-	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

-	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.
