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@16 29 date flags text
meillo@7 30
meillo@15 31 where:
meillo@16 32 date is YYYY-MM-DD
meillo@15 33 flags is ONE or ZERO of
meillo@16 34 #ann for an anniversary
meillo@16 35 #ev for an event
meillo@15 36 and zero or more of
meillo@16 37 #w<n> to set the warn-in-advance time to n days
meillo@15 38 (don't include the brackets! :)
meillo@16 39 #to<date>
meillo@16 40 #for<days>
meillo@15 41 to specify the length of time taken by an
meillo@16 42 event, for example a holiday
meillo@16 43 separated by spaces.
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.
