%\section{Usage}
%
% All of this is quite simple code. What happens
% is that some extra lines for use in tabulars are defined and
% included in the original definition of |tabular| and
% |tabular*|. These have a bit of extra vertical space which breaks
% the use of vertical rules in tabular's, which is why the old
% definitions are saved as |TABULAR| and |TABULAR*|.
%
% There are some variations on |\cline|. I moved internal commands out of the
% definition of |tabular| so they could be used in |tabular*| easily. \\[6pt]
% |\rcline| == hbox 3pt to the left\\
% |\lcline| == hbox 3pt to the right\\
% |\lrcline| == both \\
% |\rlcline| == |\lrcline| (to provide symmetry)
%
% All of the environments have
% been changed so that they also set the value of |\@tabwidth|, which
% is needed by |klufloa.sty|.
%
% |tabular*| has been adjusted to flush out the excess space over all
% columns instead of to the right of the last one. This is controlled
% by the value of |\stretchtabsep|, whose default value equals |\hfil|
%

% |\hline| has been redefined to provide some extra vertical
% space. Unforunately, we could not do the same for |\cline| and
% friend, because there can be more than one in one row. The old value
% of |\hline| is saved in |\savehline| in case you need it.
%
% |\arraystretch| is left to it's default value, but we did want extra
% spacing, so |\strut| is redefined (indirectly) to give some.
%
% And then, the entire tabular is saved in a |\hbox| so we can measure
% it up later. (See above for why we need to know this). There is a
% grouping level added to stop definitions from running away, but
% maybe this isn't needed. Not sure.
% We enclose all this in an |\AtBeginDocument| so that, if array.sty
% is loaded, the code will be executed on top of array.sty.
