       mhc - Message Harmonized Calendaring system


       This  manual  page  documents briefly the mhc file format.  This manual
       page was written for the  Debian  GNU/Linux  distribution  because  the
       original program does not have a manual page.


       Mhc  file  format  is based on STD11/RFC822: Standard for the format of
       ARPA Internet text messages.  In mhc file, the following  extra  header
       fields are used.

              Date of event in format yyyymmdd.  You can specify multiple date
              with space separated like:

                 X-SC-Day: 19990409 19990413

              which means April 9th 1999 and April 13th 1999.

              Time of event in format hh:mm-hh:mm or hh:mm.  For  event  which
              has  no  meanings  about  time,  you  can leave it empty in this

              Period of event in yyyymmdd-yyyymmdd.  You can omit  start  date
              or  end  date, like "19991121-".  X-SC-Duration: is used only to
              limit date specified by X-SC-Day: or  X-SC-Cond,  so  you  can’t
              describe  event  date only by X-SC-Duration:.  If X-SC-Duration:
              is empty, it means no limit.

              Condition of event date by using following keyword.

                 00-31 Day of month.

                 1st 2nd 3rd 4th 5th Last Week in month.

                 Sun Mon ... Sat Day of week.

                 Jan Feb ... Dec Month


                 X-SC-Cond: Tue Fri
                        Every Tuesday and Friday.

                 X-SC-Cond: 31 Aug
                        Every August 31th.

                 X-SC-Cond: 1st 3rd Fri
                        Every 1st and 3rd Friday.

                 X-SC-Cond: Fri
                 X-SC-Day: !19990409
                        Every Friday, but except April 9th 1999.

                 X-SC-Cond: Fri 13
                        Every 13th and Every Friday, not 13th Friday.

              Hint for alarm of event.  Currently, mhc.el doesn’t alaram,  but
              gemcal  will  pop-up  alarm  window.   It  will be useful if you
              transfer this event to PalmOS.  In X-SC-Alarm:, you can  specify
              the  number  (1  to 99) with suffix such as minute, hour or day.
              For example,

                 X-SC-Alarm: 10 minutes
                        Alarm 10 minutes before event.

                 X-SC-Alarm: 3 hour
                        Alarm 3 hours before event.

                 X-SC-Alarm: 3 day
                        Alarm 3 day before event.

              Subject of event. unstructured?

              Location of event. unstructured?

              Category  of  event.   Any  keyword,  space  separeated.    Case
