+USAGE='[--interactive | -i] [-v] [--force-rebase | -f] [--onto <newbase>] [<upstream>|--root] [<branch>]'
+LONG_USAGE='git-rebase replaces <branch> with a new branch of the
+same name. When the --onto option is provided the new branch starts
+out with a HEAD equal to <newbase>, otherwise it is equal to <upstream>
+It then attempts to create a new commit for each commit from the original
+<branch> that does not exist in the <upstream> branch.
+
+It is possible that a merge failure will prevent this process from being
+completely automatic. You will have to resolve any such merge failure
+and run git rebase --continue. Another option is to bypass the commit
+that caused the merge failure with git rebase --skip. To restore the
+original <branch> and remove the .git/rebase-apply working files, use the
+command git rebase --abort instead.
+
+Note that if <branch> is not specified on the command line, the
+currently checked out branch is used.
+
+Example: git-rebase master~1 topic
+
+ A---B---C topic A'\''--B'\''--C'\'' topic
+ / --> /
+ D---E---F---G master D---E---F---G master

-USAGE='[--interactive | -i] [-v] [--force-rebase | -f] [--onto <newbase>] [<upstream>|--root] [<branch>]'
-LONG_USAGE='git-rebase replaces <branch> with a new branch of the
-same name. When the --onto option is provided the new branch starts
-out with a HEAD equal to <newbase>, otherwise it is equal to <upstream>
-It then attempts to create a new commit for each commit from the original
-<branch> that does not exist in the <upstream> branch.
-
-It is possible that a merge failure will prevent this process from being
-completely automatic. You will have to resolve any such merge failure
-and run git rebase --continue. Another option is to bypass the commit
-that caused the merge failure with git rebase --skip. To restore the
-original <branch> and remove the .git/rebase-apply working files, use the
-command git rebase --abort instead.
-
-Note that if <branch> is not specified on the command line, the
-currently checked out branch is used.
-
-Example: git-rebase master~1 topic
-
- A---B---C topic A'\''--B'\''--C'\'' topic
