meillo@7	26 We're getting there. At the moment, the file used by default is ~/.birthdays
meillo@7	27 under UNIX, or C:\PERSONAL\BDAYS.LST under DOS, but this can be overridden on
meillo@7	28 the command line. The file has the following format:
meillo@7	29
meillo@7	30 name/event/whatever=date flags
meillo@7	31 where:
meillo@7	32 date is dd/mm, dd/mm/yy (assumes 20th century!) or dd/mm/yyyy
meillo@7	33 flags is ONE or ZERO of
meillo@7	34 o bd for a birthday (default)
meillo@7	35 o ann for an anniversary
meillo@7	36 o ev for an event
meillo@7	37 and zero or more of
meillo@7	38 o w <n> to set the warn-in-advance time to n days (don't include the
meillo@7	39 brackets! :)
meillo@7	40 o to <date>
meillo@7	41 o for <days>
meillo@7	42 to specify the length of time taken by an event, for example a
meillo@7	43 holiday.
meillo@7	44
meillo@7	45 Comment lines are preceeded by #.
meillo@7	46
meillo@7	47 Note: If you deviate from this format, I cannot guarantee anything about
meillo@7	48 it's behaviour. In most cases, it will just quietly ignore the error,
meillo@7	49 which probably isn't ideal behaviour. Oh, well.
