% \title{Typesetting with the\\ Computer Modern Bright fonts}
% \author{Walter Schmidt}
% \date{(\fileversion{} -- \filedate)}
% \maketitle
%
% \section{Description}
% The \LaTeX{} macro package +cmbright+ 
% supports typesetting with the font family `Computer Modern Bright'
% in traditional (OT1) or extended (T1, Cork) encoding.
% Loading this package will effect the following:
% \begin{itemize}\small
% \item The default sans serif font family will be CM Bright.
% \item 
% The sans serif font family will be the default for the whole document,
% in text and math mode.
% \item The default typewriter font family will be CM Typewriter Light,
% which blends better with CM Bright 
% than the \texttt{cmtt} fonts do.
% \item The leading for the font sizes +\normalsize+, +\small+{} and 
% +\footnotesize+{} will be increased.
% \end{itemize}
%
% To typeset with CM Bright in traditional encoding for both text and
% math mode you have put the following command in the preamble:
% \begin{verse}
% +\usepackage{cmbright}+
% \end{verse}
%
% If you want to use the extended (T1) encoding in text mode:
% \begin{verse}
% +\usepackage{cmbright}+\\
% +\usepackage[T1]{fontenc}+
% \end{verse}
%
% CM Bright fonts are available as fontseries +m+
% and +bx+. In the medium series, there is a
% slanted shape, too. If \textit{italic} is requested, it will be 
% replaced by the slanted font.
%
% All the standard fonts for typesetting mathematics are provided.
% A new mathematical alphabet +\mathbold+ provides bold slanted
% letters.
% There is, however, no bold +\mathversion+ to bolden complete formulae.
%
% \section*{Problems and known bugs}
% \begin{itemize}
% \item With the CM Bright fonts the line width may be larger than
% with CM Roman at the same size. This package, however, does \emph{not}
% change the document layout. 
% \item Macro packages which read the
% current value of +\baselineskip+
% must be loaded  \emph{after} +cmbright+.
% \item The OT1 encoded CM Bright fonts do not provide a +\pounds+ sign.
% \item The oldstyle numerals are taken from the mathematical font.
% This may be incompatible to future versions of \LaTeX.
% \end{itemize}

%
% \section*{The code}
% \subsection*{Default font families}
% The sans serif font family will be the default one:
%    \begin{macrocode} 
%<*cm>
\renewcommand{\familydefault}{\sfdefault}
%    \end{macrocode}
% CM Bright will be the default sans serif font family:
%    \begin{macrocode}
\renewcommand{\sfdefault}{cmbr}
%    \end{macrocode}
%
% CM Typewriter Light will be the default typewriter font family,
% because the usual +cmtt+ fonts look too dark in combination with CM Bright:
%    \begin{macrocode}
\renewcommand{\ttdefault}{cmtl}
%    \end{macrocode}
%
% \subsection*{Mathematical fonts}
% Definitions which remain unchanged are commented out:
%    \begin{macrocode}
\DeclareSymbolFont{operators} {OT1}{cmbr}{m}{n}
\DeclareSymbolFont        {letters} {OML}{cmbrm}{m}{it}
\DeclareSymbolFont        {symbols} {OMS}{cmbrs}{m}{n}
% \DeclareSymbolFont {largesymbols} {OMX}{cmex}{m}{n}
%
% \DeclareSymbolFontAlphabet    {\mathrm} {operators}
% \DeclareSymbolFontAlphabet{\mathnormal} {letters}
% \DeclareSymbolFontAlphabet   {\mathcal} {symbols}
%
\DeclareMathAlphabet{\mathit} {OT1}{cmbr}{m}{sl}
\DeclareMathAlphabet{\mathbf} {OT1}{cmbr}{bx}{n}
\DeclareMathAlphabet{\mathtt} {OT1}{cmtl}{m}{n}
%    \end{macrocode}
% Despite its name +\mathrm+ is not a font with serifs,
% but it is, what the user expects it to be:
% it's the upright font used e.\,g. for operator names.
%
% We do not set up a bold +\mathversion+, but we make a bold
% slanted mathematical font available:
%    \begin{macrocode}
\DeclareMathAlphabet{\mathbold}{OML}{cmbrm}{b}{it}
%    \end{macrocode}
%
% \subsection*{Font sizes and leading}
% The +\baselineskip+ should be larger than with CM Roman. For text sizes,
% i.e. 8--12\,pt, a value of $1.25 \times \mathrm{designsize}$ is recommended.

% \subsection*{Old-style numerals}
% Old-style numerals are taken from CM Bright, too:
%    \begin{macrocode}
\def\oldstylenums#1{%
   \begingroup
    \spaceskip\fontdimen\tw@\font
    \usefont{OML}{cmbrm}{\f@series}{it}%
    \mathgroup\symletters #1%
   \endgroup
}
%    \end{macrocode}
% In the future this may change; old-style numerals could be
% taken from the `text companion font', thus even providing `oldstyle
% bold extended'~\dots
%
% \subsection*{Patches}
% With a \LaTeX{} release previous to 1995/06/01
% some macros from the \LaTeX{} kernel and the standard classes
% must be redefined, because they explicitely select a font with serifs:
%    \begin{macrocode}
%<*patch>
\typeout{*}
\typeout{* This package contains patches so that it can be}
\typeout{* used with a LaTeX release previous to June 1995.}
\typeout{* However, if your LaTeX is from 1995/06/01 or newer,}
\typeout{* you MUST redo the installation of the `cmbright'}
\typeout{* files in order to generate this package again,}
\typeout{* without these patches!}
