hg merge [-P] [-f] [[-r] REV]

merge working directory with another revision

    The current working directory is updated with all changes made in
    the requested revision since the last common predecessor revision.

    Files that changed between either parent are marked as changed for
    the next commit and a commit must be performed before any further
    updates to the repository are allowed. The next commit will have
    two parents.

    ``--tool`` can be used to specify the merge tool used for file
    merges. It overrides the HGMERGE environment variable and your
    configuration files. See :hg:`help merge-tools` for options.

    If no revision is specified, the working directory's parent is a
    head revision, and the current branch contains exactly one other
    head, the other head is merged with by default. Otherwise, an
    explicit revision with which to merge with must be provided.

    :hg:`resolve` must be used to resolve unresolved files.

    To undo an uncommitted merge, use :hg:`update --clean .` which
    will check out a clean copy of the original merge parent, losing
    all changes.

    Returns 0 on success, 1 if there are unresolved files.
