meillo@8	22 ===============================================================================
meillo@0	23
meillo@8	24 Input is read through standard input. For example: bday < ~/.birthdays
meillo@8	25 The input (file) has to have the following format:
meillo@7	26
meillo@8	27 text=date flags
meillo@7	28
meillo@8	29 where:
meillo@8	30 date is yyyy-mm-dd
meillo@8	31 flags is ONE or ZERO of
meillo@8	32 bd for a birthday (default)
meillo@8	33 ann for an anniversary
meillo@8	34 ev for an event
meillo@8	35 and zero or more of
meillo@8	36 w <n> to set the warn-in-advance time to n days (don't include the
meillo@8	37 brackets! :)
meillo@8	38 to <date>
meillo@8	39 for <days>
meillo@8	40 to specify the length of time taken by an event, for example a holiday.
meillo@7	41
meillo@8	42 Lines preceeded by # are treated as comments.
meillo@7	43
meillo@8	44 Note: If you deviate from this format, I cannot guarantee anything about
meillo@8	45 it's behaviour. In most cases, it will just quietly ignore the error,
meillo@8	46 which probably isn't ideal behaviour. Oh, well.
