% Unpacking:

%
% Documentation:
%    (a) If flexisym.drv is present:

%    (b) Without flexisym.drv:
%           latex flexisym.dtx; ...

% Before declaring any math characters active, we have to take care of

% latter is because
% \begin{quote}
%   In case some alternative math fonts are loaded
%   later. [\fn{amsmath.dtx}]
% \end{quote}
% The problem arises because \pkg{flexisym} sets the mathcode of all
% symbols to $32768$ which is illegal for a \cs{mathchardef}. 
%
% We have to remove the assignments from the \cs{AtBeginDocument} hook

%
%
% For each math font package we define a corresponding symbol file
% with extension \fn{sym}. The Computer Modern base is called
% \opt{cmbase} and \opt{mathpazo} and \opt{mathptmx} corresponds to
% the packages. The definitions are almost identical as they mostly
% concern the positions in the math font encodings. Look for
% differences in \cs{joinord}, \cs{relbar} and \cs{Relbar}. If you
% inspect the source code, you'll see that the support for
% \pkg{mathptmx} didn't require any work but I thought it better to
% create a \fn{sym} file to maintain a uniform interface.
%
% \begin{aside}
% Open question on \verb"!" and \verb"?": maybe they
% should have type `Pun' instead of `DeR'.    Need to
% search for uses in math in AMS archives.    Or, maybe add a special
% `Clo' type for them: non-extensible closing delimiter.

% \section{Some compound symbols}
% The following symbols are not robust in standard \LaTeX\ 
% because they use \verb"#" or \cs{mathpalette} (which is not
% robust and contains a \verb"#" in its expansion): \cs{angle},
% \cs{cong}, \cs{notin}, \cs{rightleftharpoons}.   
% 
% In this definition of \cs{hbar}, the symbol is cobbled together
% from a math italic h and the cmr overbar accent glyph.   
%    \begin{macrocode}
\DeclareFlexSymbol{\hbarOrd}{Ord}{OT1}{16}
\DeclareFlexCompoundSymbol{\hbar}{Ord}{\hbarOrd\mkern-9mu h}
%    \end{macrocode}
% For \cs{surd}, the interior symbol gets math class 1
% (cumulative operator) to make the glyph vertically centered on the
% math axis, but the desired horizontal spacing is the spacing for a
% mathord.    (Couldn't it just be class mathopen, though?   )
%    \begin{macrocode}
\DeclareFlexSymbol{\surdOrd}{Ord}{OMS}{70}
\DeclareFlexCompoundSymbol{\surd}{Ord}{\mathop{\surdOrd}}
%    \end{macrocode}
% As shown in this definition of \cs{angle}, rule dimens are not
% allowed to use math-units, unfortunately.   
%    \begin{macrocode}
\DeclareFlexCompoundSymbol{\angle}{Ord}{%
  \vbox{\ialign{%
      $\m@th\scriptstyle##$\crcr
      \notRel\mathrel{\mkern14mu}\crcr
      \noalign{\nointerlineskip}%
      \mkern2.5mu\leaders\hrule \@height.34pt\hfill\mkern2.5mu\crcr
  }}%
}
%    \end{macrocode}
% The \cs{not} function, which is defined in the \pkg{flexisym}
% package, requires a suitably defined \cs{notRel} symbol.   
%    \begin{macrocode}

%    \end{macrocode}
% .   
%    \begin{macrocode}
\DeclareFlexCompoundSymbol{\mapsto}{Rel}{\mapstoOrd\rightarrow}
%    \end{macrocode}
% The \cs{@vereq} function ends by centering the whole
% construction on the math axis, unlike \cs{buildrel} where the base
% symbol remains at its normal altitude.    Furthermore,
% \cs{@vereq} leaves the math style of the top symbol as given
% instead of downsizing to scriptstyle.   
%    \begin{macrocode}
\DeclareFlexCompoundSymbol{\cong}{Rel}{\mathpalette\@vereq\sim}
%    \end{macrocode}
