	Added copyright notices and LICENSE file.

2.0.3	2009-02-18
        Added the function ut_root(const ut_unit* unit, int root) to
        return a root of a unit (e.g., "m2/s2" -> "m/s").

2.0.2	2008-12-02
	Changed order of calls to ut_set_status() and
	ut_handle_error_message() so that the status value is always set

	handlers to determine the cause of the message.

2.0.1	2008-11-13
	Added parsing of timestamps that have dashes and colons but also
	use "T" (e.g., "seconds since 1970-01-01T00:00:00Z").

	Corrected the regular expressions for matching the character-set
	specifier in the udunits2(1) program.

2.0.0	2007-07-18
	Initial release.
