                CHANGES in TimeWarp version 1.0-7 (2013-03-20)
CHANGES
    o   fix partial matching in data frame in holidays()

                CHANGES in TimeWarp version 1.0-5 (2012-03-10)
CHANGES
    o   make dateParse() able to handle dates like '2012.03.10'

                CHANGES in TimeWarp version 1.0-4 (2012-01-27)
CHANGES
    o   make the error.how argument in dateMatch() accept the
        value 'stop', which causes dateMatch() to stop with
        an error if no matching date is found.

    o   allow the how argument in dateMatch() to take a two-part
        value, e.g., how='nearest.stop' is equivalent to
	how='nearest' and error.how='stop'.

                CHANGES in TimeWarp version 1.0-3 (2011-12-21)
CHANGES
    o   make dateSeq() return zero length sequence when given
        start and end dates that align to be zero length, rather
        than stopping with an error.

                CHANGES in TimeWarp version 1.0-2 (2011-12-19)
CHANGES
    o   dateFormat() dynamically figures out if the system needs
    	or can handle date format specs like %02m.

                CHANGES in TimeWarp version 1.0-1 (2011-12-18)
CHANGES
    o   Removed the default 'bizdays' for argument 'by' in
        dateWarp() - the argument 'by' must be specified if
	it is needed.
    o   All functions that manipulate dates are now generic so
    	that they return the same class of object as they are
	given: character, Date, POSIXct, and POSIXlt.
