-# SHORT DESCRIPTION
-#
-# This script makes it easy to fix up commits in the middle of a series,
-# and rearrange commits.
#
# The original idea comes from Eric W. Biederman, in
-# http://article.gmane.org/gmane.comp.version-control.git/22407

-OPTIONS_SPEC="\
-git-rebase [-i] [options] [--] <upstream> [<branch>]
-git-rebase [-i] (--continue | --abort | --skip)
---
- Available options are
-v,verbose display a diffstat of what changed upstream
-onto= rebase onto given branch instead of upstream
-p,preserve-merges try to recreate merges instead of ignoring them
-s,strategy= use the given merge strategy
-no-ff cherry-pick all commits, even if unchanged
-m,merge always used (no-op)
-i,interactive always used (no-op)
- Actions:
-continue continue rebasing process
-abort abort rebasing process and restore original branch
-skip skip current patch and continue rebasing process
-no-verify override pre-rebase hook from stopping the operation
-verify allow pre-rebase hook to run
-root rebase all reachable commmits up to the root(s)
-autosquash move commits that begin with squash!/fixup! under -i
