% \section*{Introduction}
%
% This document describes the \textbb{bbold} math alphabet. This
% is an open (or `blackboard bold') geometric sans serif, intended
% mainly for use in mathematics, but which may prove useful for
% decorative work.
%
% To use the fonts in \LaTeXe, you select the |bbold| package,
% and then use the |\mathbb| command to get blackboard bold
% mathematics, |\textbb| for text, or |\bbfamily| for longer text.
% The full font is:
% \begin{center}
% \bbfamily
% \fonttable
% The bbold font family.
% \end{center}
% This was the first full font I implemented, and has a number of
% dubious design features. It is very geometric, and the stress
% does not conform to that of most Latin fonts---this was an attempt to
% imitate real blackboard handwriting. The difference in widths
% between `\textbb{a}' and `\textbb{b}' is very noticable. The lip of
% the `\textbb{r}' is horrible. However, the uppercase latin letters
% look passable, and they're almost the only ones anyone ever uses.

%
% \section{Installation}
%
% To begin with, the |bbold| package is
% installed by running \LaTeXe{} on this document, so we begin with
% the installation procedure. This needs to use \LaTeXe:
% \begin{macrocode}
%<*install>
\NeedsTeXFormat{LaTeX2e}
% \end{macrocode}
% First of all, we write out a little |.ins| file which creates the
% |bbold| package:
% \begin{macrocode}
\begin{filecontents}{bbold.ins}
\generateFile{bbold.sty}{f}{
\from{bbold.dtx}{package}}
\generateFile{fonttabl.sty}{f}{
\from{bbold.dtx}{fonttabl}}
\generateFile{Ubbold.fd}{f}{
\from{bbold.dtx}{fontdef}}
\end{filecontents}
% \end{macrocode}
% Then we do some horrible low-level hacks to run docstrip on
% |bbold.ins|:
% \begin{macrocode}
\bgroup
\makeatletter
\let\@@end=\relax
\def\batchfile{bbold.ins}
\input{docstrip}
\egroup
% \end{macrocode}
% That's it for the installation:
% \begin{macrocode}
%</install>
% \end{macrocode}
%
% \section{Documentation}
%
% We now provide the documentation driver for this document:
% \begin{macrocode}
%<*driver>
\documentclass{ltxdoc}
\DisableCrossrefs
\OnlyDescription
\usepackage{bbold,fonttabl}
% \end{macrocode}
% Then we produce the documentation:
% \begin{macrocode}
\begin{document}
\DocInput{bbold.dtx}
\end{document}
%</driver>
% \end{macrocode}
%
% \section{The package}
%
% We can now implement the |bbold| package.
% \begin{macrocode}
%<*package>
\NeedsTeXFormat{LaTeX2e}
\ProvidesPackage{bbold}[1994/04/06 Bbold symbol package]
% \end{macrocode}
% \begin{macro}{\mathbb}
% \begin{macro}{\textbb}
% \begin{macro}{\bbfamily}
% These are the three user commands. They are just simple calls to
% \LaTeXe{} font selection.
% \begin{macrocode}
\newcommand{\bbfamily}{\fontencoding{U}\fontfamily{bbold}\selectfont}
\newcommand{\textbb}[1]{{\bbfamily#1}}
\DeclareMathAlphabet{\mathbb}{U}{bbold}{m}{n}
%</package>
% \end{macrocode}
% \end{macro}
% \end{macro}
% \end{macro}
%
% \section{The font definitions}
%
% The font definitions for the \textbb{bbold} fonts are:
% \begin{macrocode}
%<*fontdef>
\DeclareFontFamily{U}{bbold}{}
\DeclareFontShape{U}{bbold}{m}{n}
{ <5> <6> <7> <8> <9> gen * bbold
<10> <10.95> bbold10
<12> <14.4> bbold12
<17.28> <20.74> <24.88> bbold17
}{}
%</fontdef>
% \end{macrocode}
%
% \section{A font table package}
%
% The following macros are stolen from |testfont.tex| and can be used
% to print font samples.
