% Added Acknowledge and Data_Use_Policy to archive.m.  Fixed getxxx functions
% to use dodsmsg instead of stdout for errors/info.  Made ChangeLog so that it's
% in Emacs format.  All changes for release 3.0.0 -- dbyrne 99/05/12
%
% Revision 1.17  1999/05/13 01:24:17  root
% Added Acknowledge and Data_Use Policy.  Fixed some bugs.  Changed any
% messages to use to use 'dodsmsg' script instead of just displaying to stdout.
%
% Revision 1.16  1999/03/04 13:13:31  root

%
%
% Fixed bug in unpack that deleted all returning names for datasets with
% no empty strings in the required fields.  Fixed vectorization of day2year
% and add workaround for a FLOP bug I found on ix86 machines.  Fixed calendar
% day to yearday conversion error in nscat30cat.m.  Added workaround for writeval
% bug in nscat30.m (2 server lines force 2 loaddods calls).  Fixed a bunch
% of bugs in new SSM/I code submitted by Rob Morris, JPL.  Added SSM/I, CZCS,
% Levitus (1982), World Ocean Atlas monthly, seasonal, and annual datasets and
% Mauna Loa CO2 record.  Fixed a logic error in urieccat.m. -- dbyrne, 98/11/29
