% This file contains \LaTeXe\ package files needed to use
% Lucida Bright fonts, and \texttt{.fd} files for the fonts as
% named by Y\&Y. The \texttt{.fd} and metric files for the Berry-naming
% scheme are available in \texttt{fonts/metrics/bh} on CTAN.
%
% The Lucida Bright font families:
%
% Note that the `demi bold' Lucida fonts are classed as `b' (bold)
% in \LaTeX. The only `bold' font in the Lucida collection is
% the bold sans serif font, which is classed as `ub' (ultra bold).

\iflucida@expert
%    \end{macrocode}
% If we have the LucidaBright Expert set, we'll draw them from the
% upright math font.  That way we can get bold math to work on upright
% upper case Greek.
%
% Why doesn't this work?
%\begin{verbatim}
% \documentclass{article}
% \usepackage{lucidabr}
% $\mathbf{\Sigma}$
% \end{document}
%\end{verbatim}
% The answer lies in the meaning of |\mathbf|; as fntguide.tex says,
% it is for alphabetic switching. The straight lucida style says
%\begin{verbatim}
%  \DeclareMathSymbol{\Sigma}{\mathalpha}{largesymbols}{'326}
%\end{verbatim}
% and the |\mathalpha| signifies that the |\Sigma| can change with the
% alphabet; so this in fact looks for |\char'326| in the ``mathbf''
% alphabet when we ask for that. That is defined with
%\begin{verbatim}
% \SetMathAlphabet{\mathbf}{bold}{\operator@encoding}{\rmdefault}{b}{n}
%\end{verbatim}
% ie normal text Lucida bold. It all works in CMR because the text fonts
% have Greek, which is why the symbols are defined as \mathalpha; in
% addition, the alphabets like |\mathbf| \emph{explicitly} ask for OT1:
%\begin{verbatim}
%\DeclareMathAlphabet      {\mathbf}{OT1}{cmr}{bx}{n}
%\end{verbatim}
% so it works in T1 encoding too.
%
% When we get the symbols from other fonts in Lucida, we should no
% longer classify the fonts as |\mathalpha|, since the mechanism
% doesn't function. So we use |\mathord| instead, and you
% only get bold Greek if you change |\mathversion|.
% At least it's consistent.
%
% If, however, we are using the Times mixture, we can keep
% |\mathalpha|, as we have the right font layouts around.
