-% This is the driver file that produces this documentation.
-% We use the document class provided by the \LaTeXe\ distribution
-% for producing the documentation.
-% \begin{macrocode}
-%<*driver>
-\documentclass[12pt]{ltxdoc}

-\usepackage{verbatim}

-% \section{Introduction}
-%
-% This package is a minimal one that allows access to the three
-% common AMS symbol font families. To use it, you will need the
-% |amsfonts| package.
-%
-% \section{User interface}
-%
-% The package needs to be included with the command
-% \begin{verbatim}
-% \usepackage[defs]{ams}
-% \end{verbatim}
-% Its effect is to prepare the symbol fonts |msam| and |msbm|
-% and the fraktur font |eufm|. Specification of option |defs|
-% causes all the usual AMS symbol definitions to be made.
-% For instance, after this one can obtain $\curvearrowright$ by
-% typing |$\curvearrowright$|.
-%
-%
-% \DescribeMacro{\Bbb}
-% \newcommand{\SF}{$\langle$\textit{sub-formula}$\rangle$}
-% The command |\Bbb{|\SF|}| typesets \SF\ in blackboard bold.
-% For instance, |\Bbb{ANYTHING}| produces \Bbb{ANYTHING}.
-% Care must be taken to ensure that \SF\ contains only uppercase
-% letters. The math style modifier is |\mathbb|.
-%
-% The commonest letters in mathematics are defined by the commands
-% |\C|, |\F|, |\N|, |\Q|, |\R|, |\T| and |\Z|, producing \C, \F,
-% \N, \Q, \R, \T, \Z\ respectively.
-%
-% \DescribeMacro{\frak}
-% \DescribeMacro{\goth}
-% |\frak| and |\goth| are similar to |\Bbb| except that they use the
-% fractur font, and are not limited to uppercase. Thus |\frak{K}|
-% produces \frak{K}. There is a math style modifier |\mathfrak| too.
-%
-% |\Bbb|, |\frak| and |\goth| work in text and math modes.
-%
-% \DescribeMacro{\MakeBbb}
-% The command |\MakeBbb{X}| has the effect of setting |\X| to expand
-% to |\Bbb{X}|, and thus further blackboard bold symbols are easily
-% defined.

-% \section{Identification}
-%
-% This package can only be used with \LaTeXe, so
-% an appropriate message is displayed when another
-% format is used.
-% \begin{macrocode}
-%<*ams>
-\NeedsTeXFormat{LaTeX2e}[1995/12/01]
-% \end{macrocode}
-%
-%
-% Announce the package name and its version:
-% \begin{macrocode}
-\ProvidesPackage{ams}[1996/01/09]
-% \end{macrocode}
-%
-% And display it on the terminal (and the log file):
-% \begin{macrocode}
-\typeout{Package `ams' <\filedate>.}
-\typeout{\Copyright}
-% \end{macrocode}
-%
-% \section{The definition option}
-%
-% There is a single option |defs| that is recognized.
-% \begin{macrocode}
-\DeclareOption{defs}{\AtEndOfPackage{\RequirePackage{amssymb}}}
-\ProcessOptions
-% \end{macrocode}
-%
-% \section{Defining the interface}
-%
-% We load the |amsfonts| package.
-% \begin{macrocode}
-\RequirePackage{amsfonts}
-% \end{macrocode}
-% We make |\Bbb|, |\goth| and |\frak| work in text mode too.
-% \begin{macrocode}
-\def\frak#1{\ensuremath{\mathfrak{#1}}}
-\def\Bbb#1{\ensuremath{\mathbb{#1}}}
-\let\goth\frak
-% \end{macrocode}
-%
-% The next command is a little trickier, but is worth the effort.
-% \begin{macrocode}
-\def\MakeBbb#1{%
- \edef\tmp{%
- \noexpand\def\csname#1\endcsname
- {\noexpand\protect\csname p#1\endcsname}%
- \noexpand\def\csname p#1\endcsname
- {\noexpand\Bbb{#1}}%
- }%
- \tmp
-}
-% \end{macrocode}
-% We can now define short forms of standard symbols.
-% \begin{macrocode}
-\MakeBbb{C}
-\MakeBbb{F}
-\MakeBbb{N}
-\MakeBbb{Q}
-\MakeBbb{R}
-\MakeBbb{T}
-\MakeBbb{Z}
-% \end{macrocode}
-%
-% We tell the user how to define all of the AMS symbols by name.
-% \begin{macrocode}
-\typeout{Use option defs to define all the AMS symbol names}
-% \end{macrocode}
-%
-% Another job is to replace the awful |cm| inequality symbols.
-% Thus, |a\leq b| will now produce $a\leq b$. We also define the
-% symbols in package |latexsym|, but taking equivalents from the
-% AMS fonts. ($\mho$, $\Join$, $\Box$, $\Diamond$, $\leadsto$
-% $\sqsubset$, $\sqsupset$, $\lhd$, $\unlhd$, $\rhd$ and $\unrhd$.)
