         Newmail is a program to allow monitoring of mailboxes in  an
         intelligent fashion.  It is based loosely on biff(1) and the
         version of newmail that was distributed with Elm 1.7.
         The basic operation is that the program will check the  list
         of  specified  mailboxes each interval seconds and will list
         any new mail that has arrived in any of the mailboxes, indi-
         cating the sender name, and the subject of the message.
         Each entry displayed can be in a number of different formats
         depending  on the mode of the program, the number of folders
         being monitored, and the status of the message.   If  you're
         running  it as a window (e.g. ``-w'' or invoked as wnewmail)
         then the output will be similar to:
            sender name - subject of message
            Priority: sender name - subject of message
         where <sender name> is either the name of the person sending
         it, if available (the ARPA 'From:' line) or some other brief
         indication of origin.   If you are the sender, <sender name>
         will  be  replaced by "to <recipient name>".  If there is no
         subject, the message  "<no  subject>"  will  appear  on  the
         Folders are indicated by having the folder name appear first
         on the output line, as in:
            folder: sender name - subject of message
         If you're running newmail without the windows  option,  then
         the  output  is more suitable for popping up on an otherwise
         active screen, and will be formatted:
            >> New mail from sender name - subject of message
            >> Priority mail from sender name - subject of message
         Again, with folder names indicated as a prefix.
         The flags available are:
         -d        This will turn on the  debugging,  verbose  output
                   mode.   It  is  not  recommended that you use this
                   option unless you're interested in actually debug-
                   ging the program.
         -i interval
                   This will change the frequency  that  the  program
                   checks  the  folders to the interval specified, in
                   seconds.  The default interval for the program  is
                   60  seconds.   Note: if you change the interval to
                   less than 10 seconds, the program  will  warn  you
                   that it isn't recommended.
         -w        Use of the ``-w'' flag will  simulate  having  the
                   program  run  from  within a window (e.g. the more
                   succinct output format, and so on).  Most  likely,
                   rather than using this option you should be simply
                   invoking wnewmail instead.
         File specs are made up of two components,  the  folder  name
         and  the  prefix  string,  the latter of which can always be
         omitted.  The format is foldername=prefixstring, and you can
         specify folders by full name, by simply the name of the user
         whose mailbox should be monitored, or by  the  standard  Elm
         metacharacters to specify your folder directory (e.g. ``+'',
         ``='', or ``%'').
         Folders that cannot be opened due to  permission  mismatches
         will  cause  the program to immediately abort.  On the other
         hand, files that do not exist will continue  to  be  checked
         every  interval  seconds,  so  some care should be exercised
         when invoking the program.
         The program will run until you log out  or  explicitly  kill
         it,  and  can  internally reset itself if any of the folders
         shrink in size and then grow again.
         The default folder to monitor is always your incoming  mail-


         Some example invocations:
              $ newmail
         will check your incoming mailbox every 60 seconds.
              $ newmail  -i  15  joe  root
         will  monitor  the  incoming  mailboxes  for   ``joe''   and
         ``root'', checking every 15 seconds for new mail.
              $ newmail  "mary=Mary"  +postmaster=POBOX
         will monitor the incoming mailbox for user ``mary'', prefix-
         ing all messages with the string ``Mary'', and the folder in
         the users maildir directory called ``postmaster'', prefixing
         all of those messages with ``POBOX''.
         You can also have more complex monitoring too, for example:
              $ newmail  -i  30  $LOGNAME=me  ${LOGNAME}su=myroot   /tmp/mbox
         will check every 30 seconds for the users mailbox, a mailbox
         that  is  the  users  login-name  with ``su'' appended (e.g.
         ``joe'' would become ``joesu'') and the file /tmp/mbox, pre-
         fixing  new  mail  for  each  with  ``me'',  ``myroot''  and
         ``mbox'' respectively.
