     """move changeset (and descendants) to a different branch
 
     Rebase uses repeated merging to graft changesets from one part of
     history (the source) onto another (the destination). This can be
     useful for linearizing *local* changes relative to a master
     development tree.
 
     You should not rebase changesets that have already been shared
     with others. Doing so will force everybody else to perform the
     same rebase or they will end up with duplicated changesets after
     pulling in your rebased changesets.
 
     If you don't specify a destination changeset (``-d/--dest``),
     rebase uses the tipmost head of the current named branch as the
     destination. (The destination changeset is not modified by
     rebasing, but new changesets are added as its descendants.)
 
     You can specify which changesets to rebase in two ways: as a
     "source" changeset or as a "base" changeset. Both are shorthand
     for a topologically related set of changesets (the "source
     branch"). If you specify source (``-s/--source``), rebase will
     rebase that changeset and all of its descendants onto dest. If you
     specify base (``-b/--base``), rebase will select ancestors of base
     back to but not including the common ancestor with dest. Thus,
     ``-b`` is less precise but more convenient than ``-s``: you can
     specify any changeset in the source branch, and rebase will select
     the whole branch. If you specify neither ``-s`` nor ``-b``, rebase
     uses the parent of the working directory as the base.
 
     By default, rebase recreates the changesets in the source branch
     as descendants of dest and then destroys the originals. Use
     ``--keep`` to preserve the original source changesets. Some
     changesets in the source branch (e.g. merges from the destination
     branch) may be dropped if they no longer contribute any change.
 
     One result of the rules for selecting the destination changeset
     and source branch is that, unlike ``merge``, rebase will do
     nothing if you are at the latest (tipmost) head of a named branch
     with two heads. You need to explicitly specify source and/or
     destination (or ``update`` to the other head, if it's the head of
     the intended source branch).
 
     If a rebase is interrupted to manually resolve a merge, it can be
     continued with --continue/-c or aborted with --abort/-a.
 
     Returns 0 on success, 1 if nothing to rebase.
