+% \section{Introduction}
+%
+% This package was written originally by Frank Mittelbach and Rainer
+% Sch\"opf; later it was moved into the AMSFonts distribution
+% with only minor modifications. It can be used with \LaTeXe{} with
+% no dependency on the \pkg{amsmath} package.
+%
+% This file sets up some font shape definitions to use the Euler
+% script symbols in math mode. These fonts are part of the AMSFonts
+% collection which can be found on many \TeX{} servers. It is also
+% directly available from the AMS and from \TeX{} user groups.
+%
+% \DescribeMacro\EuScript
+% The expected normal use of the Euler Script alphabet is as a
+% substitute for the Computer Modern calligraphic alphabet found in
+% \fn{cmsy}. Therefore we change the meaning of \cn{mathcal}.
+% \begin{verbatim}
+% \[ \mathcal{A} = \EuScript{A} \neq \CMcal{A} \]
+%\end{verbatim}
+% will produce
+% \[ \mathcal{A} = \EuScript{A} \neq \CMcal{A} \]
+%
+% Here is a complete table of the beautiful letters drawn by Hermann
+% Zapf:
+% \begin{displaymath}
+% \newcommand{\E}[1]{\EuScript{#1} &}
+% \begin{array}{*{10}c}
+% \E{A} \E{B} \E{C} \E{D} \E{E} \E{F} \E{G} \E{H} \E{I} \\
+% \E{J} \E{K} \E{L} \E{M} \E{N} \E{O} \E{P} \E{Q} \E{R} \\
+% \E{S} \E{T} \E{U} \E{V} \E{W} \E{X} \E{Y} \E{Z}
+% \end{array}

+%
+% Package identification.
+% \begin{macrocode}
+\NeedsTeXFormat{LaTeX2e}% LaTeX 2.09 can't be used (nor non-LaTeX)
+[1994/12/01]% LaTeX date must be December 1994 or later
+%<euscript>\ProvidesPackage{euscript}[2001/10/01 v2.2d Euler Script fonts]
+%<eucal>\ProvidesPackage{eucal}[2001/10/01 v2.2d Euler Script fonts]
+% \end{macrocode}
+%
+% We have three things to do: 1) identify the current package,
+% 2) enlarge the font shape tables and 3) define the \meta{math
+% alphabet identifier}.
+%
+% The font shapes for the Euler Script medium and bold are defined
+% in the amsfonts.fdd file which comes with the AMS font package.
+% We repeat their default definition here for reference only.
+% \begin{verbatim}
+% \DeclareFontFamily{U}{eus}{\skewchar\font'60}
+% \DeclareFontShape{U}{eus}{m}{n}{%
+% <5><6><7><8><9>gen*eusm%
+% <10><10.95><12><14.4><17.28><20.74><24.88>eusm10}{}
+% \DeclareFontShape{U}{eus}{b}{n}{%
+% <5><6><7><8><9>gen*eusb%
+% <10><10.95><12><14.4><17.28><20.74><24.88>eusb10}{}
+%\end{verbatim}
+%
+% \begin{macro}{\EuScript}
+% Now we define the \meta{math alphabet identifier} \cn{EuScript}
+% both for the normal and the bold math version
+% \begin{macrocode}
+\DeclareMathAlphabet\EuScript{U}{eus}{m}{n}
+\SetMathAlphabet\EuScript{bold}{U}{eus}{b}{n}
+% \end{macrocode}
+% \end{macro}
+%
+% For flexibility and backward compatibility with versions 2.1c and
+% earlier, we save the old meaning of \cn{mathcal} as \cn{CMcal}, and
+% use \cn{EuScript} as the initial name of the new math alphabet.
+% Notice that we don't do any checking to make sure the previous
+% version of \cn{mathcal} actually refers to \fn{cmsy}.
+% \begin{macrocode}
+\newcommand{\CMcal}{}
+\let\CMcal=\mathcal
+% \end{macrocode}
+%
+% The \opt{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. See \fn{amsfonts.dtx} for more
+% discussion.
+% \begin{macrocode}
+\DeclareOption{psamsfonts}{%
+ \DeclareFontFamily{U}{eus}{\skewchar\font'60}%
+ \DeclareFontShape{U}{eus}{m}{n}{<-6>eusm5<6-8>eusm7<8->eusm10}{}%
+ \DeclareFontShape{U}{eus}{b}{n}{<-6>eusb5<6-8>eusb7<8->eusb10}{}%
+}
+% \end{macrocode}

+% \pkg{euscript}, and \pkg{eufrak} packages.
