'''share a common history between several working directories'''

    Initialize a new repository and working directory that shares its
    history with another repository.

    NOTE: using rollback or extensions that destroy/modify history
    (mq, rebase, etc.) can cause considerable confusion with shared
    clones. In particular, if two shared clones are both updated to
    the same changeset, and one of them destroys that changeset with
    rollback, the other clone will suddenly stop working: all
    operations will fail with "abort: working directory has unknown
    parent". The only known workaround is to use debugsetparents on
    the broken clone to reset it to a changeset that still exists
    (e.g. tip).
