This is an NSFormatter subclass to parse ISO 8601 strings into NSDate
objects and format NSDate objects into ISO 8601 strings. It supports
calendar, week, and ordinal date formats in both directions.

New in version 0.5 is the NSFormatter nature. Previously, the parser
and unparser were categories upon NSCalendarDate. The new version is
completely NSCalendarDate-free, which means (a) it requires Tiger and
(b) it won't break when NSCalendarDate goes away.

Also new is the Bitbucket repository, where you can file bug reports.
