% Modified to include bold blackboard families by WJM on March 3 1992
% Modified to include some special symbols
%
%
% This document-style option defines four new fonts for LaTeX with
% the old font selection scheme:
% the bold math italic font, the bold sans-serif font and the italic 
% sans-serif font.
% The commands \bfi, \sfb and \sfi are defined here; automatic
% size-changes are enable by adding a line of code to the commands
% \vpt etc. from lfonts.tex.
% In math, we want to have the following mapping of family to font:
%
%     Family    Font
%     ------    ----
%     \bfi      cmmib10, boldface italic
%     \sfb      cmssbx10, bold sans-serif 
%     \sfi      cmssi10, sans-serif italic
%     \Bbb      msbm10, bold blackboard 
%
% The following fonts are loaded, the others are loaded on demand.
%
\font\tenbfi = cmmib10
\font\sevenbfi = cmmib10 %cmmib7
\font\fivebfi = cmmib10 %cmmib5
\font\tensfb = cmmib10 %cmssbx10
\font\sevensfb = cmss8
\font\fivesfb = cmr5
\font\tensfi = cmssi10
\font\sevensfi = cmssi8
\font\fivesfi = cmr5
\font\sevenBbb = cmmib10 %msbm7
\font\fiveBbb = cmmib10 %msbm5
\font\tenBbb = cmmib10 %msbm10
\font\eightBbb = cmmib10 %msbm8

% Size changing
%
% We have to take care here, since the goal is to add something to the
% definition of commands like \vpt, \xpt, etc. In order to do this
% the commands are redefined in terms of themselves. To get this
% right, the first-level expansion is stored in a token register.
% The definition for the commands \pbfi, \psfb and \psfi are also stored
% in a token register for the same reason.
% The commands are redefined globally, using \xdef.
%
% First we start a group, to keep the use of the token registers local.
