% \cs{SMC} \emph{isn't} small caps~--- Barbara Beeton says she thinks
% of it as ``big small caps''.  She says (modulo capitalisation of
% things\dots):
% \begin{quote}
%   For the things it's used for, regular small caps are not
%   appropriate~--- they're too small.  Real small caps are
%   appropriate for author names (and are so used in continental
%   bibliographies), section headings, running heads, and, on
%   occasion, words to which some emphasis is to be given.  \cs{SMC}
%   was designed to be used for acronyms and all-caps abbreviations,
%   which look terrible in small caps, but nearly as bad in all caps
%   in the regular text size.  The principle of using ``one size
%   smaller'' than the text size is similar to the design of caps in
%   German~--- where they are smaller relative to lowercase than are
%   caps in fonts intended for English, to improve the appearance of
%   regular text in which caps are used at the heads of all nouns, not
%   just at the beginnings of sentences.
% \end{quote}
%
% We define this in terms of the memory of the size currently selected
% that's maintained in \cs{@currsize}: if the user does something
% silly re.~selecting fonts, we'll get the wrong results.  The
% following code is adapted from |relsize.sty| by Donald Arseneau and
% Matt Swift, from a 2.09 original by Bernie Cosell.  (Note that the
% order of examination of \cs{@currsize} is to get the commonest cases
% out of the way first.)
