meillo@15	24 =====================================================================
meillo@9	25
meillo@15	26 Input is read through standard input. For example: bday < ~/.birthdays
meillo@15	27 The input (file) has to have the following format:
meillo@0	28
meillo@15	29 text=date flags
meillo@7	30
meillo@15	31 where:
meillo@15	32 date is yyyy-mm-dd
meillo@15	33 flags is ONE or ZERO of
meillo@15	34 bd for a birthday (default)
meillo@15	35 ann for an anniversary
meillo@15	36 ev for an event
meillo@15	37 and zero or more of
meillo@15	38 w <n> to set the warn-in-advance time to n days
meillo@15	39 (don't include the brackets! :)
meillo@15	40 to <date>
meillo@15	41 for <days>
meillo@15	42 to specify the length of time taken by an
meillo@15	43 event, for example a holiday.
meillo@7	44
meillo@15	45 Lines preceeded by # are treated as comments.
meillo@7	46
meillo@15	47 Note: If you deviate from this format, I cannot guarantee anything about
meillo@15	48 it's behaviour. In most cases, it will just quietly ignore the
meillo@15	49 error, which probably isn't ideal behaviour. Oh, well.
