meillo@0 27 We're getting there. At the moment, the file used by default is ~/.birthdays
meillo@0 28 under UNIX, or C:\PERSONAL\BDAYS.LST under DOS, but this can be overridden on
meillo@0 29 the command line. The file has the following format:
meillo@0 30
meillo@0 31 name/event/whatever=date flags
meillo@0 32 where:
meillo@0 33 date is dd/mm, dd/mm/yy (assumes 20th century!) or dd/mm/yyyy
meillo@0 34 flags is ONE or ZERO of
meillo@0 35 o bd for a birthday (default)
meillo@0 36 o bir for a birthday (exactly equivalent to `bd')
meillo@0 37 o ann for an anniversary
meillo@0 38 o ev for an event
meillo@0 39 and zero or more of
meillo@0 40 o w<n> to set the warn-in-advance time to n days (don't include the
meillo@0 41 brackets! :)
meillo@0 42 o to<date>
meillo@0 43 o for<days>
meillo@0 44 to specify the length of time taken by an event, for example a
meillo@0 45 holiday.
meillo@0 46
meillo@0 47 Comment lines are preceeded by #.
meillo@0 48
meillo@0 49 Note: If you deviate from this format, I cannot guarantee anything about
meillo@0 50 it's behaviour. In most cases, it will just quietly ignore the error,
meillo@0 51 which probably isn't ideal behaviour. Oh, well.
