+%
+% \begin{abstract}
+% This package provides a set of big delimiters, intermediate to those
+% of the original \TeX{}, and also much bigger. It also provides very
+% wide accents (including two new ones: parenthesis and triangle). These
+% symbols are included in a font which has Don's \texttt{cmex10} as
+% lower ASCII part.
+% \end{abstract}
+%
+% \section{Installation}
+%
+% This package consists of (a) a font, written in Metafont, (b) a \LaTeX{}
+% style file, (c) a FD file for the OMX encoding using the new font.
+% To build the font put all the Metafont files somewhere where your
+% Metafont can find them (for example in texmf/fonts/src/public/yhmath)
+%
+% Then launch Metafont at least once on |yhcmex10| so that at least one
+% TFM file exists when you'll start typesetting (|dvips| and similar
+% programs will create the PKs, don't worry).
+%
+% Then take the |OMXyhex.fd| file and put it together with your other FD
+% (Font Definition) files; and |yhmath.sty| together with your other
+% \LaTeX{} styles. Have fun!
+%
+% \section{Availability}
+%
+% Don Knuth's code is included in Metafont files, so this code is under
+% the usual \TeX ware \copyright opyright conditions. My code is
+% postcard-ware (if you like it and find it is worth a postcard + a stamp +
+% the mental effort of writing a word [optional!] and the physical effort
+% of going to the nearest mailbox, then do it!).
+%
+% Everything is on CTAN, and if there are upgrades you will be informed
+% in the usual way.
+%
+% \section{Very big delimiters}
+% I never liked those parentheses of matrices which become almost
+% immediately straight. In traditional math typography, parentheses stay
+% curved, even if they are very big. So I decided to play around with \TeX's
+% \texttt{charlist} font property, and make some more of those big delimiters.
+% I also did intermediate sizes (for all ``big'' delimiters). Here are some
+% examples :
+%
+% \begin{gather}
+% \begin{pmatrix} a & b\\ c & d\end{pmatrix}
+% \begin{pmatrix} a & b & c\\ d & e & f\\ g & h & i\end{pmatrix}
+% \begin{pmatrix} a & b & c & d\\ e & f & g & h\\ i & j & k & l\\
+% m & n & o & p\end{pmatrix}
+% \\
+% \begin{pmatrix} a & b & c & d & e\\ f & g & h & i & j\\
+% k & l & m & n & o\\ p & q & r & s & t\\ u & v & w & x & y\end{pmatrix}
+% \begin{pmatrix} a & b & c & d & e & f \\ g & h & i & j & k & l \\
+% m & n & o & p & q & r \\ s & t & u & v & w & x \\ y & z & \alpha &
+% \beta & \gamma & \delta\end{pmatrix}
+% \end{gather}
+%
+%
+% \section{A new \AmS-\LaTeX{}-like matrice-like environnement}
+%
+% Since I did also ``very big'' versions of the ``left angle'' and ``right
+% angle'' symbols, why not making ``matrices'' with them as delimiters?
+% I have never seen such a mathematical object, but perhaps was it just
+% because this constructions wasn't available yet? (this is a chicken and egg
+% story).
+%
+% \DescribeMacro{amatrix}
+% I called this new \AmS-\LaTeX-like environment \texttt{amatrix} (``a'' for
+% ``angle'').
+% I hope AMS people will just love it and include it into
+% \AmS-\LaTeX!\footnote{Talking of \AmS-\LaTeX{} there are a few more macros
+% I would like to see included, see next section.}
+%
+% Here are the same matrices as above, with angles instead of parentheses:
+%
+% \begin{gather}
+% \begin{amatrix} a & b\\ c & d\end{amatrix}
+% \begin{amatrix} a & b & c\\ d & e & f\\ g & h & i\end{amatrix}
+% \begin{amatrix} a & b & c & d\\ e & f & g & h\\ i & j & k & l\\
+% m & n & o & p\end{amatrix}
+% \\
+% \begin{amatrix} a & b & c & d & e\\ f & g & h & i & j\\
+% k & l & m & n & o\\ p & q & r & s & t\\ u & v & w & x & y\end{amatrix}
+% \begin{amatrix} a & b & c & d & e & f \\ g & h & i & j & k & l \\
+% m & n & o & p & q & r \\ s & t & u & v & w & x \\ y & z & \alpha &
+% \beta & \gamma & \delta\end{amatrix}
+% \end{gather}
+%
+% \section{New roots}
+%
+% Roots got bigger as well, so that now the ``vertical root'' comes
+% much later. Example :
+%
+% $$
+% \sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{\sqrt{%
+% \sqrt{\sqrt{\sqrt{\sqrt{\sqrt x}}}}}}}}}}}}
+% $$
+%
+% \section{A few things missing from \AmS-\LaTeX{} v1.2}
+%
+% \DescribeMacro{\adots}
+% In \AmS-\LaTeX{} there is a |\ddots| command for diagonal dots. How about
+% antidiagonal ones? There are matrices called anti-symmetric, and for
+% them we need the notation ``dots going up''. I define a |\adots| macro,
+% with a code symetric to |\ddots|, here is the result: $\adots$.
+%
+% \DescribeMacro{\ring}
+% Another thing missing in all \TeX{} \& Co. packages: the ring accent,
+% used in topology for the interior of a space. I define a macro |\ring|
+% to be used in math mode. Here is the result: if $X=[0,1]$ then
+% $\ring{X}=]0,1[$.
+%
+% \section{Very wide accents}
+%
+% \DescribeMacro{\widetriangle}\DescribeMacro{\wideparen}
+% I added some more hats and tildes, so that you can get really
+% wide accents now; see the examples below:
+%
+% $$
+% \widehat{A},
+% \widehat{AB},
+% \widehat{ABC},
+% \widehat{ABCD},
+% \widehat{ABCDE},
+% \widehat{ABCDEF},
+% \widehat{ABCDEFG}
+% $$
+%
+% $$
+% \widetilde{A},
+% \widetilde{AB},
+% \widetilde{ABC},
+% \widetilde{ABCD},
+% \widetilde{ABCDE},
+% \widetilde{ABCDEF},
+% \widetilde{ABCDEFG}
+% $$
+%
+% I also designed two new
+% accents: the triangle accent |\widetriangle| and the parenthesis accent
+% |\wideparen|:
+%
+% $$
+% \widetriangle{A},
+% \widetriangle{AB},
+% \widetriangle{ABC},
+% \widetriangle{ABCD},
+% \widetriangle{ABCDE},
+% \widetriangle{ABCDEF},
+% \widetriangle{ABCDEFG}
+% $$
+%
+% $$
+% \wideparen{A},
+% \wideparen{AB},
+% \wideparen{ABC},
+% \wideparen{ABCD},
+% \wideparen{ABCDE},
+% \wideparen{ABCDEF},
+% \wideparen{ABCDEFG}
+% $$
+%
+%
+%
+% The former is used (in France only??) to show that the notation $ABC$,
+% where $A,B,C$ are three points, means a triangle and not an angle.
+% See what I mean? $\widetriangle{ABC}$ is a triangle, $\widehat{ABC}$
+% is an angle.
+%
+% The latter is used when we want a non-expansible accent to be applied
+% to more than one letters at once. Of course \AmS-\LaTeX{} has given a
+% solution to this (place the symbols between parentheses and the accent
+% as an exponent of the right parenthesis), by I happen not to like that
+% solution. For example if I want to write ``the interior of $[0,1]$''
+% I prefer to see
+% $$\widering{[0,1]}$$
+% than
+% $$([0,1])\ring{}$$
+% don't you?
+%
+% And of course this notation is not my invention, I saw it in many French
+% math books (ever heard of Nick Bourbaki?).
+%
+% \DescribeMacro{\widering}
+% I call this macro |\widering|, because it plays the r\^ole of a wide
+% symbol (and since the ring can't be widened, a parenthesis is used).
+% Here are some more examples (the first one coded as |\ring{A}|):
+%
+% $$
+% \ring{A},
+% \widering{AB},
+% \widering{ABC},
+% \widering{ABCD},
+% \widering{ABCDE},
+% \widering{ABCDEF},
+% \widering{ABCDEFG},
+% $$

+%
+% \section{The code}
+% \setlength{\parindent}{0pt}
+%
+% \begin{macrocode}
+%<*package>
+% \end{macrocode}
+%
+% We require that the \textsf{amsmath} package is loaded:
+% \begin{macrocode}
+\RequirePackage{amsmath}
+% \end{macrocode}
+%
+% First of all we have to ask \LaTeX{} to use our brand new font
+% for ``large symbols''
+% \begin{macrocode}
+\DeclareSymbolFont{largesymbols}{OMX}{yhex}{m}{n}
+% \end{macrocode}
+%
+% Next, the four ``wide'' accents are defined, in a way similar to
+% \LaTeX{} and not to \AmS-\LaTeX{}, so \texttt{yhmath} must be
+% loaded after |amsmath|!
+% \begin{macrocode}
+\DeclareMathAccent{\widetilde}{\mathord}{largesymbols}{"65}
+\DeclareMathAccent{\widehat}{\mathord}{largesymbols}{"62}
+\DeclareMathAccent{\widetriangle}{\mathord}{largesymbols}{"E6}
+\DeclareMathAccent{\wideparen}{\mathord}{largesymbols}{"F3}
+% \end{macrocode}
+%
+% The |amatrix| environment is defined
+% \begin{macrocode}
+\newenvironment{amatrix}{\left\langle\matrix}{\endmatrix\right\rangle}
+% \end{macrocode}
+% And now the |\adots| macro for anti-diagonal dots. This is just the
+% |\ddots| command, mirrored
+% \begin{macrocode}
+\def\adots{\mathinner{\mkern2mu\raise\p@\hbox{.}
+\mkern2mu\raise4\p@\hbox{.}\mkern1mu
+\raise7\p@\vbox{\kern7\p@\hbox{.}}\mkern1mu}}
+% \end{macrocode}
+%
+% Following the way \AmS-\LaTeX{} defines math accents, here is the
+% definition of |\ring|.
+% family.
+% \begin{macrocode}
+\edef\@tempa#1#2{\def#1{\mathaccent\string"\noexpand\accentclass@#2 }}
+\@tempa\ring{017}
+% \end{macrocode}
+%
+% And finally here is a (clumsy) definition of |\widering|, that is
+% a ring over an horizontal parenthesis.
+% \begin{macrocode}
+\newcommand{\widering}[1]{\overset{\smash{\lower1.333ex\hbox{$%
+\displaystyle\ring{}$}}}{\wideparen{#1}}}
+% \end{macrocode}
+%
+%
+% \begin{macrocode}
+%</package>
+% \end{macrocode}
+% \begin{macrocode}
+%<*fdfile>
+% \end{macrocode}
+% Follows the FD file. Here we define the |yhex| family, at least for
+% the OMX (Old Math Extensible symbols) encoding
+% \begin{macrocode}
+\ProvidesFile{OMXyhex.fd}
+ [1996/01/04 v1.0 YH's humble contribution to TeX maths]
