NAME

       mhc - Message Harmonized Calendaring system

DESCRIPTION

       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.

FIELDS

       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.

       X-SC-Day:
              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.

       X-SC-Time:
              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 field.

       X-SC-Duration:
              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.

       X-SC-Cond:
              Condition of event date by using following keyword.

                 00-31 Day of month.

              Examples,

       X-SC-Alarm:
