%    \section{Introduction}
%
%    The fonts la and lla provide glyphs for producing a handwritten
%    writing as tought in primary school. These fonts have been
%    written by Johannes Heuer. They can be found  on
%    the CTAN in the directory \texttt{tex-archive/fonts/calligra}.
%    This package provides means to use those fonts in \LaTeXe.
%
%
%    \section{Usage}
%
%    This file can be used as a package by placing its name
%    in the argument of |\usepackage|. Afterwards the font families la
%    and lla are defined. This could also have been done by providing two
%    font definition files.
%
%    The font definitions in this file scale down the original fonts to
%    \LaTeX{} choose the right baselineskip. The original size of the la
%    fonts can be selected with the commands |\LARGE\la| or |\LARGE\lla|.
%
%
%    \DescribeMacro{\la}
%    The command |\la| changes the current font family to la and the
%    encoding to T1. Usually this should be used in a \TeX{} group only.
%
%    \DescribeMacro{\textla}
%    This macro typesets its argument in the la font.
%
%    \DescribeMacro{\lla}
%    The command |\lla| changes the current font family to lla and the
%    encoding to T1. Usually this should be used in a \TeX{} group only.
%
%    \DescribeMacro{\textlla}
%    This macro typesets its argument in the lla font.
%
%    \DescribeMacro{\llafill}
%    The command |\llafill| fills the rest of the line with lines as used
%    in the lla font. The result may be unexpected if not used where the
%    font family is not lla.
%
%    \DescribeMacro{\llaline}
%    The command |\llaline| takes its argument and adds lines as used in
%    the lla font underneath. This is similar to the |\underline|
%    macro.
%
%    \StopEventually{}
%
%
%    \section{Implementation}
%
%
%    First we declare a new font family for the la font.
%    \begin{macrocode}
\DeclareFontFamily{T1}{la}{}
%    \end{macrocode}
%
%    This font is only available in the normal shape. Here we can get the
%    desired font by (silently) scaling the only present la14. Since the
%    design size is 14 we have to scale down the font by $1/14=0.71428571$.
% 
%    \begin{macrocode}
\DeclareFontShape{T1}{la}{m}{n}{<->s*[0.71428571]la14}{}
%    \end{macrocode}
%
%    Now we define the next font family for the font with lines in the
%    background. 
%    \begin{macrocode}
\DeclareFontFamily{T1}{lla}{}
%    \end{macrocode}
%
%    This font is only available in the normal shape. Here we can get the
%    desired font by (silently) scaling the only present lla14. Since the
%    design size is 14 we have to scale down the font by $1/14=0.71428571$.
% 
%    \begin{macrocode}
\DeclareFontShape{T1}{lla}{m}{n}{<->s*[0.71428571]lla14}{}
%    \end{macrocode}
%
%    Now we define font changing commands.
% 
%    \begin{macro}{\la}
%    The macro |\la| selects the la family.
%    \begin{macrocode}
\DeclareRobustCommand\la{\fontfamily{la}\fontencoding{T1}\selectfont}
%    \end{macrocode}
%    \end{macro}
%
%    \begin{macro}{\textla}
%    The macro |\textla| typesets its arguments in the la font.
%    \begin{macrocode}
\newcommand\textla[1]{\begingroup
  \fontfamily{la}\fontencoding{T1}\selectfont #1\endgroup}
%    \end{macrocode}
%    \end{macro}
%
%    \begin{macro}{\lla}
%    The macro |\lla| selects the lla family.
%    \begin{macrocode}
\DeclareRobustCommand\lla{\fontfamily{lla}\fontencoding{T1}\selectfont}
%    \end{macrocode}
%    \end{macro}
%
%    \begin{macro}{\textlla}
%    The macro |\textla| typesets its arguments in the lla font.
%    \begin{macrocode}
\newcommand\textlla[1]{\begingroup
  \fontfamily{lla}\fontencoding{T1}\selectfont #1\endgroup}
%    \end{macrocode}
%    \end{macro}
%
%    \begin{macro}{\llafill}
%    The macro |\llafill| is modeled after the macro |\underline|. The
%    symbol 24 in the lla font provides just the lines.
%    \begin{macrocode}
\newcommand\llafill{\leaders\hbox{\kern.2em\symbol{24}}\hfill\symbol{24}}
%    \end{macrocode}
%    \end{macro}
%
%    \begin{macro}{\llaline}
%    The macro |\llaline| packs its argument into a box. Then a box of
%    the same size is filled with empty lines and the original box is
%    typeset in a box of width 0 afterwards.
%    \begin{macrocode}
\newcommand\llaline[1]{%
  {\lla\symbol{24}%
    \mbox{\setbox0=\hbox{#1}\hbox to \wd0{\llafill}\llap{\usebox0}}}}
%    \end{macrocode}
%    \end{macro}
%
%    \begin{environment}{llapar}
%    This environment typesets one or more paragraphs with the lla
%    font. The |\llaline| instructions are inserted automatically at
%    the end of each paragraph.
%
%    \begin{macrocode}
\newenvironment{llapar}{\par\begingroup\lla
  \let\lla@par=\par
  \def\par{\llafill\lla@par}}{\par\endgroup}
%    \end{macrocode}
%    \end{environment}
%
%    \Finale
