SYNOPSIS
--------
-'git-rebase' [-v] [--merge] [--onto <newbase>] <upstream> [<branch>]
+'git-rebase' [-v] [--merge] [-C<n>] [--onto <newbase>] <upstream> [<branch>]
'git-rebase' --continue | --skip | --abort
DESCRIPTION
-----------
-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.
+If <branch> is specified, git-rebase will perform an automatic
+`git checkout <branch>` before doing anything else. Otherwise
+it remains on the current branch.
+
+All changes made by commits in the current branch but that are not
+in <upstream> are saved to a temporary area. This is the same set
+of commits that would be shown by `git log <upstream>..HEAD`.
+
+The current branch is reset to <upstream>, or <newbase> if the
+--onto option was supplied. This has the exact same effect as
+`git reset --hard <upstream>` (or <newbase>).
+
+The commits that were previously saved into the temporary area are
+then reapplied to the current branch, one by one, in order.
It is possible that a merge failure will prevent this process from being
completely automatic. You will have to resolve any such merge failure
original <branch> and remove the .dotest 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.
-
Assume the following history exists and the current branch is "topic":
------------
This is useful when topicB does not depend on topicA.
+A range of commits could also be removed with rebase. If we have
+the following situation:
+
+------------
+ E---F---G---H---I---J topicA
+------------
+
+then the command
+
+ git-rebase --onto topicA~5 topicA~2 topicA
+
+would result in the removal of commits F and G:
+
+------------
+ E---H'---I'---J' topicA
+------------
+
+This is useful if F and G were flawed in some way, or should not be
+part of topicA. Note that the argument to --onto and the <upstream>
+parameter can be any valid commit-ish.
+
In case of conflict, git-rebase will stop at the first problematic commit
and leave conflict markers in the tree. You can use git diff to locate
the markers (<<<<<<) and make edits to resolve the conflict. For each
typically this would be done with
- git update-index <filename>
+ git add <filename>
After resolving the conflict manually and updating the index with the
<newbase>::
Starting point at which to create the new commits. If the
--onto option is not specified, the starting point is
- <upstream>.
+ <upstream>. May be any valid commit, and not just an
+ existing branch name.
<upstream>::
- Upstream branch to compare against.
+ Upstream branch to compare against. May be any valid commit,
+ not just an existing branch name.

Working branch; defaults to HEAD.
-v, \--verbose::
Display a diffstat of what changed upstream since the last rebase.
+-C<n>::
+ Ensure at least <n> lines of surrounding context match before
+ and after each change. When fewer lines of surrounding
+ context exist they all must match. By default no context is
+ ever ignored.
