DISCUSS provides its own help facility: there is an equivalent of a manual page for each command within DISCUSS, and also for ``access'' and ``specifiers''. In discuss, enter ``help foo'' for information on command or topic ``foo''. Manual pages are available for discuss and xdsc by entering ``man discuss'' and ``man xdsc'', respectively. In edsc, pressing ``?'' or ``Ctrl-h m'' will give a short summary of commands.
