    MoinMoin - DeletedPages Macro (Low-Level-Version)

    This macro shows a list of pages that have been deleted by
    ?action=delete but still exist silently on disc.
    You need to be superuser to call this macro.
    This is a low-level-version of the DeletedPages Macro and
    thus much, much faster than the normal high-level-version.

    [[DeletedPages]]
