  \end{enumerate}
  The package \file{ttfonts.sty} and the font description files
  (\file{fd}-files) are to be put into the
  \file{texinputs} path where \LaTeX\ can find them.
  
  The \file{mf}-files belong in the \file{mfinputs} path and have to
  be processed before the documentation \file{ttfonts.drv} can be 
  processed. The reason is that \TeX\ will need the \file{tfm}-files
  to use these fonts.

% \begin{abstract}\noindent
%   The use of typewriter fonts is poorly supported by standard \TeX\
%   and \LaTeX. First of all these font families lack the variety of
%   font shapes needed for pleasing documents. Hence we define some
%   relatives to the \Fam{cmtt} and \Fam{cmvtt} font families by
%   means of new driver files for \MF.
%   The use of the new fonts then is supported by the package
%   \pkg{ttfonts}.
% \end{abstract}
%
% \section*{The \pkg{ttfonts} package interface}
%   The \Fam{cmtt} font family is not intended for extensive use.
%   It was meant as a device for verbatim text such as file listings.
%
%   Nevertheless in some cases one might want to have a nice
%   typewriter font instead of the perfect \TeX\ or \LaTeX\ layout.
%   For private letters an informal style of printing seems more
%   appropriate. For first drafts that are liable to change a printing
%   is required that supports proof reading and correction of typos.
%   In this case the layout shouldn't look perfect.
%
%   The package we describe here is meant to fill this gap. It provides
%   two font families \Fam{bmtt} and \Fam{bvtt}. But first of all you
%   must load the package. Just put the line
%   \begin{quote}
%     |\usepackage{ttfonts}|
%   \end{quote}
%   into the preamble of your document. Then the typewriter type
%   fonts can be switched on
%   by |{\mttfamily...}| or |\textmtt{...}| for the monospace font and
%   by |{\vttfamily...}| or |\textvtt{...}| for the variable typewriter
%   type. 
%
%   Within these font families the notion of \textex{extended} font series
%   has a meaning and denotes spaced printing which is accessible by
%   |{\exseries...}| or |\textex{...}|.
%
%   By passing one of the following options to the package you can
%   make it influence the whole layout of your document. In this case
%   you have to say e.g.
%   \begin{quote}
%     |\usepackage[monottfonts,exemph]{ttfonts}|
%   \end{quote}
%   within the preamble of your document.
%   For each option there is a corrsponding environment of the same
%   name that allows you to switch on the settings locally.
%   \begin{itemize}
%     \item[\opt{monottfonts}] redifines |\familydefault| to be \Fam{bmtt}
%       such that a monospaced typwriter type is used as the basic font
%       family of the document. Text is typeset ragged right. 
%     \item[\opt{varttfonts}] redifines |\familydefault| to be \Fam{bvtt}
%       such that a variable typwriter type is used as the basic font
%       family of the document.
%     \item[\opt{exemph}] redfines |\em| and |\emph| to print its argument
%       spaced not italicized when the typewriter type fonts are used.
%     \item[\opt{proofreading}] is a combination of \opt{monottfonts} and
%       \opt{exemph} that additionally increases the baselineskip and the
%       indentation of paragraphs. It is meant to facilicate proof reading
%       of draft versions.
%   \end{itemize}
%   For instance
%   \begin{quote}
%     |\begin{monottfonts}|\\
%     \ldots\\
%     |\end{monottfonts}|
%   \end{quote}
%   will typeset the enclosed part of your document using the monospaced
%   typewriter type.
%
%   \begin{proofreading}
%     The rest of this section is printed in \opt{proofreading} style.
%     As you can see there is no reason not to put \emph{corrections}
%     at the margin. We may quote Leslie Lamport from the \LaTeX\ manual
%     of version 2.09.
%     \begin{quote}
%       To most readers, the printed page conveys a greater sense of
%       authority than the typewritten manuscript. It must be important
%       to be worth printing. With \LaTeX, typesetting is almost as easy
%       as typing. There is no publisher or journal editor standing
%       between the author and the reader. \LaTeX\ will not reject
%       ill-formed ideas or correct bad grammar. With the power to print
%       your own document comes the responsibility to make it worth
%       printing.
%     \end{quote}
%   \end{proofreading}
%
% \section*{Implementation}
%   \subsection*{The package}
%     First we identify the package.
%    \begin{macrocode}
%<*package>
\NeedsTeXFormat{LaTeX2e}[1995/12/01]
\typeout{Package: `ttfonts'. Version: \FileVersion\space of \FileDate.}
\ProvidesPackage{ttfonts}[\FileDate\space Version: \FileVersion\space
  typewriter type package]
%    \end{macrocode}
%     Then we anounce the two families.
%    \begin{macrocode}
\newcommand{\mttdefault}{bmtt}
\newcommand{\vttdefault}{bvtt}
%    \end{macrocode}
%     Now we define the macros for turning on the settings.
%     \begin{macro}{\mttfamily}
%    \begin{macrocode}
\newcommand{\mttfamily}{%
  \fontfamily{\mttdefault}\selectfont
}
\DeclareTextFontCommand{\textmtt}{\mttfamily}
%    \end{macrocode}
%     \end{macro}
%     \begin{macro}{\vttfamily}
%    \begin{macrocode}
\newcommand{\vttfamily}{%
  \fontfamily{\vttdefault}\selectfont
}
\DeclareTextFontCommand{\textvtt}{\vttfamily}
%    \end{macrocode}
%     \end{macro}
%     \begin{macro}{\exseries}
%    \begin{macrocode}
\newcommand{\exseries}{%
  \fontseries{x}\selectfont
}
%    \end{macrocode}
%    \begin{macrocode}
\DeclareTextFontCommand{\textex}{\exseries}
%    \end{macrocode}
%     \end{macro}
%     We now turn to the environments
%     \begin{environment}{monottfonts}
%    \begin{macrocode}
\newenvironment{monottfonts}{%
  \def\familydefault{\mttdefault}\normalfont
  \raggedright
}{}
%    \end{macrocode}
%     \end{environment}
%     \begin{environment}{varttfonts}
%    \begin{macrocode}
\newenvironment{varttfonts}{%
  \def\familydefault{\vttdefault}\normalfont
}{}
%    \end{macrocode}
%     \end{environment}
%     \begin{environment}{exemph}
%       The local |\em| command will test if the current font is typewriter
%       type. First of all we get the old definition into the
%       local one thus preserving the behaviour of |\em| on other font
%       families where spaced printing is not supported.
%    \begin{macrocode}
\newenvironment{exemph}{%
  \expandafter\def\expandafter\em\expandafter{%
%    \end{macrocode}
%       Within the local |\em| we use |\@tempa|,\ldots\ to keep changes local.
%       Hence we open a group.
%    \begin{macrocode}
    \expandafter{%
%    \end{macrocode}
%       The old definition of |\em| is stored in |\@tempc|.
%    \begin{macrocode}
      \expandafter\def\expandafter\@tempc\expandafter{%
        \em
      }%
%    \end{macrocode}
%       We use |\@tempa| and |\@tempb| to compare the current font family
%       with |\mttdefault| and |\vttdefault|. The
%       |\csname| \ldots\ |\endcsname| construction is necessary because
%       of the strange catcoding of \LaTeX's font selection mechanism.
%       If the current font is typewriterstyle we overwrite the definition
%       of |\@tempc|.
%    \begin{macrocode}
      \edef\@tempa{\csname\f@family\endcsname}%
      \edef\@tempb{\csname\mttdefault\endcsname}%
      \ifx\@tempa\@tempb
        \def\@tempc{\exseries}%
      \fi
      \edef\@tempb{\csname\vttdefault\endcsname}%
      \ifx\@tempa\@tempb
          \def\@tempc{\exseries}%
      \fi
%    \end{macrocode}
%       We want to keep the definitions of |\tempa|,\ldots\ local. But we have
%       to make a font selection outside the group we are in. This can
%       be done by first expanding |\@tempc| and then closing the current
%       group \emph{in front of it}.
%    \begin{macrocode}
    \expandafter}\@tempc
  }%
}{}
%    \end{macrocode}
%      Note that nested use of this environment will lead to more and
%      more evolved definitions of |\em|.
%
%      We don't have to care about |\emph| because this is implemented
%      by means of |\em|.
%     \end{environment}
%     \begin{environment}{proofreading}
%       First we have the global settings. Please note that macros
%       like |\exemph| are defined by means of the corresponding
%       environments.
%    \begin{macrocode}
\newenvironment{proofreading}{%
  \exemph
  \monottfonts
%    \end{macrocode}
%       Some people might say |\textrm{...}| in math mode to include
%       text that should appear in the basic font. To make this behave well
%       we delete all traces of roman fonts.
%    \begin{macrocode}  
  \let\rmdefault\mttdefault
%    \end{macrocode}
%       At last we fix the layout.
%    \begin{macrocode}
  \def\baselinestretch{1.3}%
  \reset@font
  \parindent=5em%
}{}
%    \end{macrocode}
%     \end{environment}
%     Finally we have to deal with the options.
%     This is simply done by execution the appropriate macros.
%    \begin{macrocode}
\DeclareOption{monottfonts}{\monottfonts}
\DeclareOption{varttfonts}{\varttfonts}
\DeclareOption{exemph}{\exemph}
\DeclareOption{proofreading}{\proofreading}
\ProcessOptions
%</package>
%    \end{macrocode}
%
%   \subsection*{The font description files}
%     These six files contain the declaration of all font shapes
%     for the families \Fam{bmtt} and \Fam{bvtt}.

%     First we identify the file
%    \begin{macrocode}
%<*ot1bmtt>
\ProvidesFile{ot1bmtt.fd}[\FileDate\space\FileVersion]
%    \end{macrocode}
%      Now we declare the font family.
%    \begin{macrocode}
\DeclareFontFamily{OT1}{bmtt}{}
%    \end{macrocode}
%     Here is the list of all available font shapes.
%    \begin{macrocode}
