    3.30 +	 We're getting there. At the moment, the file used by default is ~/.birthdays
    3.31 +	 under UNIX, or C:\PERSONAL\BDAYS.LST under DOS, but this can be overridden on
    3.32 +	 the command line. The file has the following format:
    3.33 +
    3.34 +	 name/event/whatever=date flags
    3.35 +	 where:
    3.36 +		 date is dd/mm, dd/mm/yy (assumes 20th century!) or dd/mm/yyyy
    3.37 +		 flags is ONE or ZERO of
    3.38 +			 o  bd  for a birthday (default)
    3.39 +			 o  bir for a birthday (exactly equivalent to `bd')
    3.40 +			 o  ann for an anniversary
    3.41 +			 o  ev  for an event
    3.42 +		 and zero or more of
    3.43 +			 o  w<n> to set the warn-in-advance time to n days (don't include the
    3.44 +	 brackets! :)
    3.45 +			 o  to<date>
    3.46 +			 o  for<days>
    3.47 +							 to specify the length of time taken by an event, for example a
    3.48 +				 holiday.
    3.49 +
    3.50 +		 Comment lines are preceeded by #.
    3.51 +
    3.52 +		 Note: If you deviate from this format, I cannot guarantee anything about
    3.53 +		 it's behaviour. In most cases, it will just quietly ignore the error,
    3.54 +		 which probably isn't ideal behaviour. Oh, well.
