 '''command to transplant changesets from another branch
 
 This extension allows you to transplant changes to another parent revision,
 possibly in another repository. The transplant is done using 'diff' patches.
 
 Transplanted patches are recorded in .hg/transplant/transplants, as a
 map from a changeset hash to its hash in the source repository.

     Selected changesets will be applied on top of the current working
     directory with the log of the original changeset. The changesets
     are copied and will thus appear twice in the history with different
     identities.
 
     Consider using the graft command if everything is inside the same
     repository - it will use merges and will usually give a better result.
     Use the rebase extension if the changesets are unpublished and you want
     to move them instead of copying them.
 
     If --log is specified, log messages will have a comment appended
     of the form::
 
       (transplanted from CHANGESETHASH)
 
     You can rewrite the changelog message with the --filter option.
     Its argument will be invoked with the current changelog message as
     $1 and the patch as $2.
 
     --source/-s specifies another repository to use for selecting changesets,
     just as if it temporarily had been pulled.
     If --branch/-b is specified, these revisions will be used as
     heads when deciding which changesets to transplant, just as if only
     these revisions had been pulled.
     If --all/-a is specified, all the revisions up to the heads specified
     with --branch will be transplanted.
 
     Example:
 
     - transplant all changes up to REV on top of your current revision::
 
         hg transplant --branch REV --all
 
     You can optionally mark selected transplanted changesets as merge
     changesets. You will not be prompted to transplant any ancestors
     of a merged transplant, and you can merge descendants of them
     normally instead of transplanting them.
 
     Merge changesets may be transplanted directly by specifying the
     proper parent changeset by calling :hg:`transplant --parent`.
 
     If no merges or revisions are provided, :hg:`transplant` will
     start an interactive changeset browser.
 
     If a changeset application fails, you can fix the merge by hand
     and then resume where you left off by calling :hg:`transplant
     --continue/-c`.
