-- | Small library for parsing different dates formats.
--   
--   This package allows to parse many different formats of dates. Both
--   absolute and relative dates are supported. Supported date formats are:
--   
--   <ul>
--   <li>DD.MM.YYYY</li>
--   <li>YYYY/MM/DD</li>
--   <li>`12 September 2012'</li>
--   <li><a>today</a>, <a>tomorrow</a>, <a>yesterday</a></li>
--   <li>`in 2 days', '3 weeks ago'</li>
--   <li>`last monday', 'next friday'</li>
--   <li>`last month' (1th of this month), `next year' (1th of January of
--   next year)</li>
--   </ul>
--   
--   4-digits years may be abbreviated (such as 12 for 2012). Both 12-hour
--   and 24-hour time formats are supported.
--   
--   User-specified date formats are supported by Data.Dates.Formats
--   module.
