%
%  This is a micture of Frank Jensen's ``beton'' package and someone
%  else's ``concmath'' package that has the features of both.  Unlike
%  ``beton'', this package defines all sizes of Concrete Roman that
%  might appear in a typical document (and several larger sizes that
%  might only appear on slides).
%
%  Since there is no Concrete Roman Bold, switch to Computer Modern
%  Sans Serif for bold text instead of Computer Modern Roman.  Two
%  serifed fonts in the same document look really oogly.  But that's
%  just my opinion.
%
%  Herman Zapf specified slightly more spacing between the lines for
%  this fonts than for Computer Modern.  To get the old line spacing,
%  which looks very tight for this font, use the option [verytight].
%  For intermediate spacing, use the option [tight].
%
%  Other options:
%	[oldstyle-equation-numbers]
%	[concrete-math]

%% Declare font shapes for sizes 29.86, 35.83 and 40 (text fonts).
