% \section{Introduction}
%    This file defines all the symbols found in the AMS symbol fonts
%    \fn{msam} and \fn{msbm}.
%

%
% \section{The Implementation}
%    First provide package identification.
%    \begin{macrocode}
\NeedsTeXFormat{LaTeX2e}% LaTeX 2.09 can't be used (nor non-LaTeX)
[1994/12/01]% LaTeX date must December 1994 or later
\ProvidesPackage{amssymb}[1996/11/03 v2.2b]
%    \end{macrocode}
%
%    The `psamsfonts' option is intended to mean that the Y\&Y/Blue Sky
%    Research PostScript versions of the AMSFonts should be used. In
%    that font set, the only \fn{.tfm} files provided below size 10 are
%    5 and 7, rather than 5,6,7,8,9. This means that if the standard
%    \fn{.fd} files are used, any attempt to use 6,8,9 point math will
%    result in error messages about missing \fn{.tfm} files. In order to
%    ensure that the proper \fn{.fd} files are used for the PS case, we
%    load them immediately. Otherwise the \fn{.fd} files would be
%    auto-loaded when \LaTeX{} encounters the first math formula in a
%    document, and the standard auto-loading mechanisms don't provide a
%    way [that I know of---mjd,7-Oct-1994] to choose the `57' varieties
%    of the \fn{.fd} files.
%    \begin{macrocode}
\DeclareOption{psamsfonts}{\PassOptionsToPackage{psamsfonts}{amsfonts}}
%    \end{macrocode}
%
%    Process options.
%    \begin{macrocode}
\ProcessOptions\relax
%    \end{macrocode}
%
%    \begin{macrocode}
%    We call the \pkg{amsfonts} package to do the font setup that we need.
%    \begin{macrocode}
\RequirePackage{amsfonts}[1995/01/01]
%    \end{macrocode}
%
%    We undefine a few symbols that were perhaps defined by the
%    \pkg{amsfonts} package (qv); otherwise \cn{DeclareMathSymbol} would
%    issue some error messages.
%    \begin{macrocode}
\let\square\relax \let\rightsquigarrow\square \let\lozenge\square
\let\vartriangleright\square \let\vartriangleleft\square
\let\trianglerighteq\square \let\trianglelefteq\square
%    \end{macrocode}
%
%    Now we define the complete set of standard symbol names for the
%    \fn{msam} and \fn{msbm} fonts. Redefinitions of symbols or commands
%    which can't be defined via \cn{DeclareMathSymbol} are already done
%    in the \pkg{amsfonts} package (for example,
