mhc

mhc(5)								File Formats Manual							    mhc(5)

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.

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

		 Sun Mon ... Sat Day of week.

		 Jan Feb ... Dec Month

	      Examples,

		 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.

       X-SC-Alarm:
	      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.

       X-SC-Subject:
	      Subject of event. unstructured?

       X-SC-Location:
	      Location of event. unstructured?

       X-SC-Category
	      Category of event.  Any keyword, space separeated.  Case ignored.

       X-SC-Recoard-Id:
	      Internal use only.
