%    \section{Introduction}
%
%    The \MF\ font twcal provides a calligraphic font. This font has been
%    written by Thomas Weinmann. It can be found on the CTAN in the
%    directory \texttt{tex-archive/fonts/twcal}.
%    This package provides means to use this font.

%    This package has been created for an article in "`Die \TeX nische
%    Kom\"odie"' \cite{dtk96.1:neugebauer:krakelig}. This article
%    contains some more details on the package and its use.
%
%
%    \section{Usage}
%
%    This file can be used as a package by placing its name
%    in the argument of |\usepackage|. Afterwards the font family twcal
%    is defined. This could also have been done by providing a
%    font definition file.
%
%
%    \DescribeMacro{\twcal}
%    The command |\twcal| changes the current font family to twcal and the
%    encoding to OT1. Usually this should be used in a \TeX{} group only
%    since it changes the font encoding and redefines the umlaut macro.
%
%    The following example on the left produces the result on the
%    right.\smallskip

%
%    \section{Implementation}
%
%
%    First we declare a new font family for the twcal font.
%    \begin{macrocode}
\DeclareFontFamily{OT1}{twcal}{}
%    \end{macrocode}
%
%    This font is only available in the normal shape. Here we can get the
%    desired font by (silently) scaling the only present fonts.
% 
%    \begin{macrocode}
\DeclareFontFamily{OT1}{twcal}{}
\DeclareFontShape{OT1}{twcal}{m}{n}{<->s*[0.7]twcal14}{}
%    \end{macrocode}
%
%    Next we define some macros to perform the mapping of umlaut
%    characters to the unusual positions used in this font.
%    \begin{macrocode}
\newcommand\twcal@a{\char26}
\newcommand\twcal@o{\char27}
\newcommand\twcal@u{\char28}
\newcommand\twcal@A{\char29}
\newcommand\twcal@O{\char30}
\newcommand\twcal@U{\char31}
%    \end{macrocode}
%
%    Now we define the font changing command.
% 
%    \begin{macro}{\twcal}
%    The macro |\twcal| selects the twcal family. 
%    \begin{macrocode}
\DeclareRobustCommand\twcal{%
  \let\twcal@original@umlaut=\"
  \def\"##1{%
    \@ifundefined{twcal@##1}{%
      \twcal@original@umlaut{##1}}{%
      \@nameuse{twcal@##1}}}%
  \fontfamily{twcal}%
  \fontencoding{OT1}%
  \selectfont}
%    \end{macrocode}
%    \end{macro}
% 
%    \begin{macro}{\texttwcal}
%    The macro |\texttwcal| typesets its argument in the twcal font. 
%    \begin{macrocode}
\newcommand\texttwcal[1]{\begingroup\twcal #1\endgroup}
%    \end{macrocode}
%    \end{macro}
%
%    \begin{macro}{\twcallogo}
%    Finally we provide the logo for this font as defined by the author
%    of the font.
%    \begin{macrocode}
\newcommand\twcallogo{\mbox{\({ 
         \lower-0.3ex\hbox{T}\kern-0.22em
         \lower0.3ex\hbox{W}\kern-0em
         \lower-0.3ex\hbox{C}\kern-0.24em
         \lower0.3ex\hbox{A}\kern-0.14em
         \lower-0.3ex\hbox{L}}\kern-0.19em
         \lower0.1ex\hbox{1}\kern-0.14em
         \lower-0.1ex\hbox{4}\)}}
%    \end{macrocode}
%    \end{macro}

% \PrintIndex
%
% \Finale
