% grbbridge: a package of LaTeX macros for typesetting bridge
%
% Experiment added 10 December 2013: ``general auction'', ``bidprob'', support for ``all pass''

% Version 2.1.1, released 05 September 2013
% Version 2.1, in development 20 August 2013
% Version 2.0, released 23 November 2011

% Version history:
% 	Version 1 was an experiment from several years ago never released to the public.
%   Version 2.0 was released 23 November 2011, providing vhand, hhand, auction, the handdiagram environment, and the deal float.
%	  Version 2.1 was released xx xxxx, enhancing vhand, and providing the ability to display several vhands with referenceable headers.
%   Version 2.1.1 improved alignment of North, table marker, and South in hand diagrams.
%   Version 2.2 added support for auctions that don't end in ``pass pass pass''; displaying single suit combinations; different spacing options in inline and hand diagrams; reimplemented the show/hide compass routine in \handdiagram.
