    place where others can get to it), you can start reviewing changesets.

    See the following help topics if you want to use the command-line
    interface:

        hg help review-review
        hg help review-comment
        hg help review-signoff
        hg help review-check

    Once you've reviewed some changesets, don't forget to push your
    comments and signoffs so other people can view them.
