meillo@0: 	 We're getting there. At the moment, the file used by default is ~/.birthdays
meillo@0: 	 under UNIX, or C:\PERSONAL\BDAYS.LST under DOS, but this can be overridden on
meillo@0: 	 the command line. The file has the following format:
meillo@0: 
meillo@0: 	 name/event/whatever=date flags
meillo@0: 	 where:
meillo@0: 		 date is dd/mm, dd/mm/yy (assumes 20th century!) or dd/mm/yyyy
meillo@0: 		 flags is ONE or ZERO of
meillo@0: 			 o  bd  for a birthday (default)
meillo@0: 			 o  bir for a birthday (exactly equivalent to `bd')
meillo@0: 			 o  ann for an anniversary
meillo@0: 			 o  ev  for an event
meillo@0: 		 and zero or more of
meillo@0: 			 o  w<n> to set the warn-in-advance time to n days (don't include the
meillo@0: 	 brackets! :)
meillo@0: 			 o  to<date>
meillo@0: 			 o  for<days>
meillo@0: 							 to specify the length of time taken by an event, for example a
meillo@0: 				 holiday.
meillo@0: 
meillo@0: 		 Comment lines are preceeded by #.
meillo@0: 
meillo@0: 		 Note: If you deviate from this format, I cannot guarantee anything about
meillo@0: 		 it's behaviour. In most cases, it will just quietly ignore the error,
meillo@0: 		 which probably isn't ideal behaviour. Oh, well.
