Command:   calendar - reminder service
Syntax:    calendar [-] [-r]
Flags:     -   Work for every user and send mail to him
           -r  Restrict multiple execution on the same day
Examples:  calendar                 # Check  calendar  file  in  current
                                      directory
           calendar                 # Normary used under the control  of
                                      cron(8)
           calendar -r              #  Normary used in /etc/rc file

     Basically calendar  program  consults  the  file  calendar  in  the
current  directory and display lines which contain today's or tomorrow's
date.  Month-day formats such as  '12/25',  'Dec.  25',  'december  25',
'*/25',  '12/*', '*/*' are recognized.  The asterisk means 'all' days or
'all' months.   On  weekends  'tomorrow'  extends  through  next  Monday
without  any  consideration  about  holidays.  To prevent ambiguity, the
formats '25 Dec.' and '25/12' are not recognized.

     When an argument - is present, calendar works for all users with  a
file  calendar in their login directories and sends them mail.  Normally
this is done daily under the control of cron.

     The -r option does its the same job as - option,  but  touches  the
calendar  to  prevents further access on the same day.  Normally this is
done in the /etc/rc file on a machine  which may be booted several times
in one day.
