SYNOPSIS
--------
-'git-rebase' [--onto <newbase>] <upstream> [<branch>]
+'git-rebase' [--merge] [--onto <newbase>] <upstream> [<branch>]
'git-rebase' --continue | --skip | --abort
--abort::
Restore the original branch and abort the rebase operation.
+--skip::
+ Restart the rebasing process by skipping the current patch.
+ This does not work with the --merge option.
+
+--merge::
+ Use merging strategies to rebase. When the recursive (default) merge
+ strategy is used, this allows rebase to be aware of renames on the
+ upstream side.
+
+-s <strategy>, \--strategy=<strategy>::
+ Use the given merge strategy; can be supplied more than
+ once to specify them in the order they should be tried.
+ If there is no `-s` option, a built-in list of strategies
+ is used instead (`git-merge-recursive` when merging a single
+ head, `git-merge-octopus` otherwise). This implies --merge.

NOTES
-----
When you rebase a branch, you are changing its history in a way that
If you would prefer to skip this patch, instead run \"git rebase --skip\".
To restore the original branch and stop rebasing run \"git rebase --abort\".

+MRESOLVEMSG="
+When you have resolved this problem run \"git rebase --continue\".
+To restore the original branch and stop rebasing run \"git rebase --abort\".
