+%
+% \section{Introduction}
+%
+%    This file defines the package |wasysym| which makes some
+%    additional characters available that come from the \texttt{wasy} fonts.
+%    These fonts were provided by Roland Waldi, Universit\"at Karlsruhe, 
+%    Germany.  
+%    Notice that the present macro package requires version~2 (1992) of 
+%    these fonts. It is not 100 \% compatible to the old 
+%    version~1 from 1989. I have provided no compatibility mode 
+%    for the old fonts! If some characters come out wrong or are
+%    missing, you have to upgrade.
+%
+%    Some of the symbols below are already provided in the T1 or TS1 
+%    (textcompanion) encodings, and |wasysm| serves only to make them 
+%    available also with the traditional (OT1-encoded) CM-Roman fonts. 
+%    Other symbols are  provided in the AMS symbol fonts, too, and can
+%    be accessed using either the |amssymb| or the |amsfonts| package.
+%
+% \section{The symbols}   
+%
+%   \subsection{Various math symbols}
+%    The following commands are valid in math mode only:
+%    \begin{quote}
+%    |\Join|~$\Join$ \quad
+%    |\Box|~$\Box$ \quad
+%    |\Diamond|~$\Diamond$ \quad
+%    |\leadsto|~$\leadsto$ \quad
+%    |\sqsubset|~$\sqsubset$ \quad
+%    |\sqsupset|~$\sqsupset$ \quad
+%    |\lhd|~$\lhd$ \quad
+%    |\unlhd|~$\unlhd$ \quad
+%    |\LHD|~$\LHD$\quad
+%    |\rhd|~$\rhd$ \quad
+%    |\unrhd|~$\unrhd$ \quad
+%    |\RHD|~$\RHD$\quad
+%    |\apprle|~$\apprle$\quad
+%    |\apprge|~$\apprge$\quad
+%    |\wasypropto|~$\wasypropto$\quad
+%    |\invneg|~$\invneg$\quad
+%    |\ocircle|~$\ocircle$\quad
+%    |\logof|~$\logof$\quad
+%    \end{quote}
+%
+%   \subsection{Integrals}
+%   The |wasy| fonts provide a set of integral sybols, which comprises
+%   multiple integrals and surface integrals, too.  
+%   \begin{itemize}
+%   \item
+%    Loading the package
+%    with the option \texttt{[integrals]} makes the following integrals available:
+%    \begin{quote}
+%    |\int|~$\int$\quad
+%    |\iint|~$\iint$\quad
+%    |\iiint|~$\iiint$\quad
+%    |\oint|~$\oint$\quad
+%    |\oiint|~$\oiint$
+%    \end{quote}
+%   Notice that the style of the |\int| and |\oint| is changed, as compared
+%   with standard \LaTeX, and matches the other integral symbols.
+%   This works with or without the |amsmath| package,  
+%   and the sequence of loading does not matter.
+%   \item
+%   If you prefer to stay with the integral symbols provided by \LaTeX
+%   (and possibly |amsmath|),
+%   but need other symbols from the \texttt{wasy} fonts,
+%   load the package with the option \texttt{[nointegrals]}.  Doing so will 
+%   neither alter any existing integral symbols nor add new ones.
+%   \item
+%   Loading the package \emph{without an option} or with the option \texttt{[compat1]}
+%   makes the following commands for integrals available:
+%    \begin{quote}
+%    |\varint|~$\int$\quad
+%    |\iint|~$\iint$\quad
+%    |\iiint|~$\iiint$\quad
+%    |\varoint|~$\oint$\quad
+%    |\oiint|~$\oiint$
+%    \end{quote}
+%   This is compatible with the behavior of |wasysym| version~1.x,
+%   but the package will not cooperate well with |amsmath| then.
+%   \end{itemize}

+%  |\LEFTCIRCLE|~\LEFTCIRCLE \quad
+%  |\Rightcircle|~\Rightcircle \quad

+%  |\RIGHTcircle|~\RIGHTcircle \quad
+%  |\leftturn|~\leftturn \quad
+%  |\rightturn|~\rightturn \quad
+%   \end{quote}
+%
+%  \subsection{Phonetic symbols}
+%
+%   \begin{quote}
+%  |\dh|~{\fontencoding{OT1}\fontfamily{cmr}\selectfont\dh} \quad
+%  |\DH|~{\fontencoding{OT1}\fontfamily{cmr}\selectfont\DH} \quad 
+%  |\thorn|~\thorn \quad
+%  |\Thorn|~\Thorn \quad
+%  |\openo|~\openo \quad
+%  |\inve|~\inve
+%   \end{quote}
+%
+%   T1-encoded fonts normally include  Eth characters of their own.
+%   The |wasy| package tries to provide  them in the OT1 encoding, too.
+%   by ``faking'' them.
+%   This should work with the Computer Modern fonts, but may fail with others.
+%
+%   The characters produced by |\thorn|, |\Thorn|, |\openo| and |\inve|  
+%   match only the CM-Roman typeface
+%   and do not change with the surrounding font family or shape.

+% \section{Changes over version~1.x}
+% \begin{itemize}
+%   \item
+%    The |\Dh| command has finally been abolished.
+%    \item
+%    The macros 
+%    |\LEFTcircle|, |\RIGHTcircle|, |\CheckedBox| and |\APLinv|
+%    start with  |\leavevmode| now, so that they work properly at the 
+%    beginning of a paragraph.
+%    \item
+%    Use of the \texttt{wasy}-style integral symbols can be controlled 
+%    via the options \texttt{[compat1]}, \texttt{[integrals]} and \texttt{[nointegrals]},
+%    with \texttt{[compat1]} being the default.
+%    \item
+%    When loaded with the \texttt{[integrals]} or \texttt{[nointegrals]} option, 
+%    the package will not clash with |amsmath|.
+% \end{itemize}
+%
+%
+% \StopEventually{}
+%
+% \section{The \dst{} modules}
+%
+% The following modules are used in the implementation to direct
+% \dst{} in generating the external files:
+% \begin{center}
+% \begin{tabular}{ll}
+%   driver & produce a documentation driver file \\
+%   package  & produce a package file \\
+%   fd     & produce a font definition file \\
+%   fdvar    & produce a \texttt{.fd} file for use with scalable fonts
+% \end{tabular}
+% \end{center}
+%
+% \section{The Implementation}
+% \subsection{The macro package}
+%
+%  With the version 1.x of |wasysym|, the definitions of the multiple 
+%  integrals would depend on whether |amsmath| was loaded additionally, and whether it 
+%  was loaded before or after |wasysym|.  Redefinition of \emph{all} integrals
+%  so as to exhibit the same style was only possible through the (almost) undocumented 
+%  macros |\newint| and |\newamsint|.  Similar problems would also arise
+%  with the Fourier math fonts.
+%  This behavior was hard to understand and somewhat unfortunate\dots
+%
+%  Three options are now introduced to control the (re)definiton of the integral macros
+%  and a ``version~1 compatibility mode'':
+%    \begin{macrocode}
+%<*package>
+\newif\ifwasy@integrals
+\newif\ifwasy@compatibility
+\DeclareOption{compat1}{%
+  \wasy@compatibilitytrue\wasy@integralsfalse}%
+\DeclareOption{integrals}{%
+  \wasy@compatibilityfalse\wasy@integralstrue}%
+\DeclareOption{nointegrals}{%
+  \wasy@compatibilityfalse\wasy@integralsfalse}%
+\ExecuteOptions{compat1}
+\ProcessOptions\relax
+%    \end{macrocode}
+%  \begin{itemize}
+%  \item
+%  By default or with the option \texttt{[compat1]}, version~2 will behave just as version~1,
+%  i.e. the macros |\varint|, |\iint|, |\iiint|, |\varoint| and |\oiint| are defined at load time.
+%  \item
+%  With the option \texttt{[nointegrals]}, the meaning of any ``standard''
+%  or AMS integral macros remains unchanged, and the additional \texttt{wasy}
+%  integrals cannot be used.
+%  Thus, one can use the other \texttt{wasy} symbols without altering the 
+%  integral signs.
+%  \item
+%  With the option \texttt{[integrals]}, the standard
+%  and (if applicable) AMS integral macros are redefined to match the style of the
+%  additional \texttt{wasy} integrals.  The definitions are deferred until 
+%  |\begin{document}|, so that other package cannot interfere.
+%  The redefined integral macros will cooperate with the |amsmath| package,
+%  if it is loaded additionally.
+%  \item
+%  The undocumented commands |\newint| and |\newamsint|, too, may turn on
+%  the redefinition of the integral commands.
+%  \end{itemize}
+%
+%  The following two macros serve to actually (re)define the integrals.
+%  The first one  is to be used if the |amsmath| package is not loaded:
+%    \begin{macrocode}
+\def\wasy@setup{%
+     \let\int\wasy@int  
+     \let\iint\wasy@iint 
+     \let\iiint\wasy@iiint 
+     \let\oint\wasy@oint 
+     \let\oiint\wasy@oiint
+} 
+%    \end{macrocode}
+%    With |amsmath|, it's a bit more complicated:
+%    \begin{macrocode}
+\def\wasy@amssetup{%
+     \let\intop\wasy@int
+     \let\iintop\wasy@iint 
+     \let\iiintop\wasy@iiint
+     \let\ointop\wasy@oint  
+     \let\oiintop\wasy@oiint
+     \def\int{\DOTSI\intop\ilimits@}%
+     \def\iint{\DOTSI\iintop\ilimits@}%
+     \def\iiint{\DOTSI\iiintop\ilimits@}%
+     \def\oint{\DOTSI\ointop\ilimits@}%
+     \def\oiint{\DOTSI\oiintop\ilimits@}%
+     \def\intkern@{\mkern-8mu}
+}
+%    \end{macrocode}
+%
+% The old undocumented commands |\newint| and |\newamsint| are changed,
+% so as to effect the same  as the |integrals| option  and issue a warning
+% message:
+%    \begin{macrocode}
+\newcommand{\newint}{%
+  \PackageWarning{wasysym}{%
+  The command \protect\newint\space is obsolete.
+  \MessageBreak
+  Load the package with the option [integrals] instead}
+  \wasy@integralstrue}
+\newcommand{\newamsint}{%
+  \PackageWarning{wasysym}{%
+  The command \protect\newamsint\space is obsolete.
+  \MessageBreak
+  Load the package with the option [integrals] instead.}
+  \wasy@integralstrue}
+%    \end{macrocode}
+%
+%
+%    To access the wasy symbols in text mode I have defined them
+%    as a new fontfamily. Since I only take single characters but
+%    don't want to write long text this is not an elegant approach. 
+%    But it works and the symbols scale according to textsize, which 
+%    is all I promised.
+%    \begin{macrocode}
+\def\wasyfamily{\fontencoding{U}\fontfamily{wasy}\selectfont}
+\DeclareTextFontCommand{\textwasy}{\wasyfamily}
+%    \end{macrocode}
+%
+% We declare a \texttt{wasy} math symbol font, too:
+%    \begin{macrocode}
+\DeclareSymbolFont{wasy}{U}{wasy}{m}{n}
+\SetSymbolFont{wasy}{bold}{U}{wasy}{b}{n}
+%    \end{macrocode}
+%
+%    We declare a new command to generate overlayed symbols:
+%    \begin{macrocode}
+\def\wasy@over#1#2{{\setbox0\hbox{$#2$}\hbox to \wd0{\hss
+    $#1$\hss}\kern-\wd0\box0}}
+%    \end{macrocode}

+%    Initially the integrals are defined with ``harmless''

+%    \end{macrocode}
+%
+% Now let's actually set up the integrals.  
+% In ``compatibility mode'' they are defined immediately at load time:
+%    \begin{macrocode}
+\ifwasy@compatibility

+  \let\oiint\wasy@oiint
+\fi
+%    \end{macrocode}
+% If the option \texttt{[integrals]} was selected, the related definitions
+% are executed only at |\begin{document}|.  Notice that the commands
+% |\newint| or |\newamsint| may appear in the preamble and turn on the
+% the redefinition of the integral macros.
