%    * bugs from version 1.1 have been fixed. 
%         * Among them the non correct behavior when
%         eulergreek and one of the symbol options were used
%         at the same time. 
%         * Also the macro \cs{Mathastext} did not
%         contrarily to what was said in the docs pick up
%         the font defaults at the time of it being used in
%         the preamble. 
%         * the endash option provoked an error when used
%         with XeTeX or LuaTeX.
%    * for brevity sake long macro names starting with
%    \cs{Mathastext\cdots} now exist in the form
%    \cs{MT\cdots} 
%    * the |endash| option is made default, as well as the
%    |alldelims| option. A new |symboldelimiters| option
%    specifies to use the Symbol font for characters others
%    then letters and digits. 
%    * the \cs{fouriervec} command must be explicitely
%    requested by the |fouriervec| option
%    * the command \cs{Mathastext} now accepts an optional
%    argument which, if present, makes \cs{Mathastext} acts
%    as \cs{MathastextDeclareVersion} with the current font
%    defaults, the optional argument giving the name of the
%    version. This mechanism allows to use |mathastext| with
%    unicode fonts (XeTeX or LuaTeX with |fontspec|)
%    * |mathastext| is more clever for the dotless i and j
%    and the hbar with respect to encoding problems; and it
%    knows also their Unicode locations.
%    }
%
% \changes{1.1}{2011/02/01}{
%   * option |italic|: this is the main change for the user. Internally we now
%   have two distinct fonts, however they differ only in shape. 
%       * the mechanism of math versions is extended to accomodate this: the
%       macros \cs{MathastextWillUse} and \cs{MathastextDeclareVersion} now
%       accept an optional argument for specifying the letters' shape  
%       * |frenchmath| sets the uppercase Latin letters nevertheless in the
%       digits font 
%       * \cs{mathnormal}, \cs{mathrm}, \cs{mathbf} work in the same way as in
%       standard \LaTeX{}, but with the |mathastext| font. But I do nothing
%       with the other default alphabet changing commands.
%   * the minus sign can be represented as an en-dash. This seems to be clever
%   enough to accomodate all 8bit encodings, not limited to OT1 or T1.
%   * the |noplusnominus| option is split into two
%   * I change the way the encoding is chosen for the math accents: I use the
%   default encoding at the time of loading. So there is nothing more in the
%   code at AtBeginDocument for this. I do not know an automatic way to go
%   from the encoding to the accent slots, and I did not want to manually
%   incorporate here all possible or at least many encodings, so basically
%   only OT1 and T1 are ok. Default to OT1. Of course in case on more than one
%   math versions, they should have the same encoding for everything to work
%   everywhere. 
%   * same change for \cs{imath}: but defaults to T1.
%   * some attention devoted to |hbar|. Works ok, or at least reasonably with
%   the fonts I tested. Adjusts to whether or not the |italic| option was used. 
%   * |defaultvec| deprecated, rather we now have \cs{fouriervec} command to
%   access the vec accent from the Fourier font. 
%   * new alphabet commands \cs{mathnormalbold}, \cs{MathEulerBold}, and
%   \cs{MathEuler} and \cs{MathPSymbol} have new names.
%   * names for the capital Greek letters which look like their Latin versions.
%   * bug fixed: the character slot for \cs{Xi} in the Symbol font was wrong.
%   **** limitations: 
%        * the \cs{pmvec} accent will not change its size when
%        used in subscripts or exponents
%        * now that internally we have two fonts for letters and
%        digits they could be entirely unrelated, it is just a
%        question of providing the user macros to pass the info to
%        the package, and to duplicate some variables. As this
%        goes really against the initial design goals, and adds
%        complications, I did not do it.}

%  \begin{abstract}
%    The |mathastext| package\footnote{This document describes |mathastext|
%    version \fileversion\ (\filedate).} propagates the document {\em text}
%    font to {\em mathematical} mode, for the letters and digits of the Latin
%    alphabet and, optionally, some further characters. The idea is to produce
%    handouts or research papers with a less book-like typography than what is
%    typical of standard \TeX\ with the Computer Modern fonts. Hopefully, this
%    will force the reader to concentrate more on the contents ;-). It also
%    makes it possible (for a document with simple mathematics) to use a quite
%    arbitrary font without worrying too much that it does not have specially
%    designed accompanying math fonts. Also, |mathastext| provides a simple
%    mechanism in order to use many different choices of (text hence, now,
%    math) fonts in the same document (not that we recommend it!).  A final
%    aspect is that |mathastext| helps sometimes produce smaller PDF files.

%
%  \section{Description of what the package does}
%
%    \subsection{Motivation}
%
%    |mathastext| was conceived as a result of frustration of
%    distributing to students \TeX-crafted mathematical handouts with
%    a subsequent realization that not much had made it to a
%    semi-permanent brain location. So, I forced \LaTeX\ to produce
%    material as if written on a primitive typewriter, a little bit
%    like the good old seminar notes of the Cartan and Grothendieck
%    days. Don't ask me if this helped, I have long since opted for a
%    positive attitude in life.
%    
%    The package |mathastext| is less extreme, but retains
%    the idea of using inside mathematics the same font as
%    is used for text for the letters of the Latin
%    alphabet and the digits:\\
%    \centerline{abcdefghijklmnopqrstuvwxyz}
%    \centerline{ABCDEFGHIJKLMNOPQRSTUVWXYZ}
%    \centerline{0123456789} By
%    default the text font will also be used for:\\
%    \DeleteShortVerb{\|}
%    \centerline{!\,?\,*\,,\,.\,:\,;\,+\,\textendash\,=\,(\,)\,[\,]\,/\,\#\,%
%    \$\,\%\,\&\,$\mathord{<}\,\mathord{>}\,\mathord{|}$\,\{\,\}
%    and $\backslash$} If the package detects at the time of
%    being loaded that the default encoding is OT1, it takes
%    out from the list
%    $\mathord{<}\,\mathord{>}\,\mathord{|}$\,\{\,\} and
%    $\backslash$.  \MakeShortVerb{\|} The option
%    |alldelims| can force re-integration in case one uses a
%    fixed-width OT1 font.
%
%    The commands \cs{mathnormal}, \cs{mathrm} and
%    \cs{mathbf} are modified but nothing is changed to
%    \cs{mathit} and the other math alphabet commands which
%    will use the default math fonts, not the text font.
%
%    A very short list of further glyphs will be also picked
%    up in or constructed from the text font: the dotless i
%    and j, the hbar and the math accents. By default the
%    en-dash \textendash{} is used for the minus sign and
%    not the hyphen character -. Version |1.11| brings a
%    better compatibility with a Unicode setting (assuming
%    that |fontspec| is made use of), but the scope of
%    |mathastext| does not include directly input 
%    letters with diacritics \'e, \`a, \"o in math
%    mode. Users of Xe\TeX{} are advised to look at the much
%    more sophisticated and encompassing |mathspec| package.
%
%    Even when typesetting simple mathematics, some glyphs
%    may have to be taken from the default math fonts, for
%    example the prime $\prime$. 
%
%    \subsection{The italic option}
%
%    In the initial version |1.0|, the package gave the same
%    shape to both letters and digits, either the one given
%    by \cs{shapedefault} at the time of loading the
%    package, or another one specified by the user, and this
%    was deliberate. This gives a very uniform look to the
%    document, so that one has to make an effort and read it
%    with attention, I explained above why I did this on
%    purpose.
%
%    Nevertheless, soon after I posted the package to CTAN, I was overwhelmed
%    by numerous\footnote{this means ``more then one.''} questions\footnote{I
%    thank in particular Tariq~\textsc{Perwez} and Kevin~\textsc{Klement} for
%    their kind remarks (chronological order).}  on how to have
%    the letters be in italic shape. 
%
%    The version |1.1| provided precisely this feature. The
%    default is still, as in version |1.0|, for everything to be
%    in upright shape, but it suffices to pass to the package the
%    option |italic|. There is now also an option |frenchmath| to
%    make the uppercase letters nevertheless upright, because this
%    is the way of traditional French mathematical typography.
%
%    \subsection{Greek letters}
%
%    Regarding the Greek letters: the default (lowercase)
%    ones from Computer Modern are slanted, hence, if the
%    |italic| option just mentioned is not made use of, they
%    will not mix well with upright letters (besides, the
%    Computer Modern typefaces are very light in comparison
%    to many text fonts). So there are options to take these
%    glyphs either from the Euler font or from the
%    Postscript Symbol font. Both are included in all
%    \LaTeX{} distributions. Although no package loading is
%    necessary for the user, nor done internally by
%    |mathastext|, the file |uzeur.fd| from the |eulervm|
%    package must be accessible to \LaTeX{} as it provides a
%    mechanism to scale by an arbitrary factor the Euler
%    font. For the Postscript Symbol font (which is included
%    in the basic \LaTeX{} distribution), |mathastext| does
%    internally what is necessary, so that in both cases
%    commands are provided so that the user can scale the
%    font with respect to nominal size.
%
%    Of course, it is also possible to access upright Greek
%    letters via loading first specific packages providing math
%    fonts, for example the |fourier| package (with option
%    `upright'). One just has to make sure to load |mathastext| as
%    the last one of the font-related packages.
%
%    \subsection{Math versions}
%
%    \LaTeX{} has two math versions (|normal| and |bold|):
%    |mathastext| provides a straightforward mechanism to define
%    many more. The encodings of the various |mathastext|-defined versions
%    can be arbitrary; but as |mathastext| decides at the time
%    when it is loaded where to look for things like the en-dash,
%    or the dotless i and j, or the math accents, which are
%    encoding-dependent, there are obviously some limitations to
%    the use of these things in more than one math
%    version. Here is an example of how this goes:
%    \begin{verbatim}
%    \usepackage[T1]{fontenc}
%    \usepackage{mathastext}
%    % Latin Modern Typewriter Proportional
%    \MTDeclareVersion{lmvtt}{T1}{lmvtt}{m}{n}
%    % Baskervald, letters in italics
%    \MTDeclareVersion[it]{baskervald}{T1}{ybv}{m}{n}
%    % Bold Helvetica, digits and operator names slanted 
%    % and letters (in math mode only) upright
%    \MTDeclareVersion[n]{helvetica}{T1}{phv}{b}{sl}
%    \begin{document}
%    \MTVersion{helvetica}
%    Hello $world!$.
%    \MTVersion[lmvtt]{baskervald}
%    Here lmvtt but $here\ baskervald$.
%    \MTVersion{normal}
%    Default font when loading mathastext, $in\ math\ also$.
%    \end{document}
%    \end{verbatim}
%    Other ways to achieve the same result:
%    \begin{verbatim}
%    \usepackage[T1]{fontenc}
%    \usepackage{mathastext}
%    \renewcommand{\rmdefault}{lmvtt}
%    \Mathastext[lmvtt]
%    \renewcommand{\rmdefault}{ybv}
%    \MTlettershape{it}
%    \Mathastext[baskervald]
%    \renewcommand{\shapedefault}{sl}
%    \renewcommand{\rmdefault}{phv}
%    \renewcommand{\mddefault}{b}
%    \MTlettershape{n}
%    \Mathastext[helvetica]
%    \begin{document}
%    \MTVersion{helvetica}
%    Hello $world!$.
%    \MTVersion[lmvtt]{baskervald}
%    Here lmvtt but $here\ baskervald$.
%    \MTVersion{normal}
%    Default font when loading mathastext, $in\ math\ also$.
%    \end{document}
%    \end{verbatim}
%    Unicode encoded fonts can also be accomodated. Here is
%    an example (a bit schizophrenic) for a Xe\TeX{} or
%    Lua\LaTeX{} user. Of course |mathastext|'s facilities
%    are very meager to specify a math font, as basically
%    they are quasi-limited to a subset of the 32-127 ascii
%    range:\footnote{see the introduction describing the
%    initial goals of this package.} the much more powerful
%    and sophisticated package |mathspec| is recommended to
%    Xe\TeX{} users.
%    \begin{verbatim}
%    \usepackage[no-math]{fontspec}
%    \setmainfont{comfortaa}
%    \usepackage{mathastext}  % the normal version uses Comfortaa
%    \setmainfont{TeX Gyre Pagella}
%    \Mathastext[pagella]     % the pagella version uses Pagella
%    \MTDeclareVersion{times}{T1}{ptm}{m}{n} 
%              %  this is a T1-times. Do not try to use this
%              %  command for a Unicode font, use rather the
%              %  \setmainfont command of |fontspec|,
%              %  followed by \Mathastext
%    \setmainfont{TeX Gyre Schola}
%    \Mathastext[schola] % and unicode TeX Gyre Schola
%    \begin{document}
%    \MTVersion{pagella}
%    This is in TeX Gyre Pagella $and\ this\ also$ (unicode font).
%    \MTVersion{times}
%    Now we are in URW Times, $here\ also$ (T1 encoded font).
%    \MTVersion[normal]{schola}
%    Text in Unicode Comfortaa and $math\ in\ Unicode\ Schola$.
%    \end{document}
%    \end{verbatim}
%    
%    
%    For basic use one does not need to worry about the purely
%    optional mechanism of math versions: to use the package, one
%    only needs loading it (the default font at the time of
%    loading the package will become the font used in
%    mathematics). Users of Xe\TeX{} and
%    Lua\LaTeX{} will need to have loaded the package |fontspec|,
%    \emph{with option} |no-math|, and \emph{before} |mathastext|.
%
%    \subsection{Main options}
%    \begin{description}
%    \item[{\tt italic, frenchmath:}] were described above (new in |1.1|).
%    \item[{\tt symbolgreek:}] the Greek letters will be taken from the
%      Postscript Symbol font.
%    \item[{\tt eulergreek:}] the Greek letters will be taken from the Euler
%      font.
%    \item[{\tt symbolmax:}] all characters other than letters and digits will
%      be taken from the Symbol font. This option also makes a number of
%      further glyphs available, including some basic mathematical arrows, as
%      well as the sum and product signs. For documents with very simple needs
%      in mathematical symbols, the options |symbolmax| (and another one
%      called |alldelims|) may give in the end a quite smaller PDF file, as
%      the Computer Modern fonts, or whatever mathematical fonts initially
%      loaded by packages for use in the document, may well be avoided
%      altogether.
%    \item[{\tt defaultmathsizes:}] the package |mathastext| opts for quite big
%      subscripts (and, copied from the |moresize| package, redefines
%      \cs{Huge} and defines \cs{HUGE}). Use this option to prevent it from
%      doing so.
%    \end{description}
%
%    \subsection{Miscellaneous}
%
%    \begin{description}
%    \item[the en-dash as minus sign:] 
%      Very often the - character from the text font does
%      not give a good minus sign. So by default, the
%      package uses the en-dash sign \textendash{}. In
%      version |1.11| of the package this should work in all
%      encodings, including Unicode (it is then assumed that
%      |fontspec| has been loaded). It is not necessary
%      anymore to pass the option |endash|, rather there is
%      |noendash| to deactivate it.
%
%
%    \item[hbar:] The definition of \cs{hbar} inherited from
%      default \LaTeX{} will in our context make use of the
%      |h| of the current math font (so for us, it is also
%      the text font, perhaps in italic shape), but the bar
%      accross the |h| will come from the original default
%      math font for letters (usually |cmmi|), and
%      furthermore its placement on the |h| can be
%      odd-looking. So we redefine \cs{hbar} to use only the
%      text font (and this will be aware of the |italic|
%      option). Our construction does not always give an
%      optimal result (and is limited to OT1 and T1
%      encodings), so an option |nohbar| deactivates
%      it. There is no \cs{hslash} provided by the package,
%      though. With version |1.11| and a Unicode font the
%      package tries to get the \cs{hbar} directly as a
%      glyph from the font.
%
%
%    \item[dotless i and j:] By default the package redefines
%      \cs{i} and \cs{j} to give the dotless i and j (if it
%      exists at all), \emph{also in math mode,} in the text
%      font. Will overwrite the default commands \cs{imath}
%      and \cs{jmath}. In version |1.11| of the package this
%      should work in all encodings, including Unicode (it
%      is then assumed that |fontspec| has been loaded, and
%      of course that the glyphs are indeed in the font).
%
%
%    \item[vec accent:] The default \cs{vec} accent is not
%      appropriate for upright letters, so  |mathastext|
%      provides a \cs{fouriervec} which takes its glyph in a
%      Fourier font, and an Ersatz \cs{pmvec} 
%      which is reasonably good looking on upright letters
%      and works with the \cs{rightarrow} glyph. Contrarily
%      to version |1.0|, the default \cs{vec} is not
%      overwritten with \cs{fouriervec}. And contrarily to
%      version |1.1|, one now needs to pass the option
%      |fouriervec| to have the math accent \cs{fouriervec}
%      defined by the package.
%
%
%    \item[math alphabets:] The \cs{mathnormal}, \cs{mathrm}, and \cs{mathbf} are
%      modified to use the text font (or the arbitrarily
%      specified font for a math version), and behave as in
%      standard \LaTeX{}. But we provide a new
%      \cs{mathnormalbold}, to access the bold letters while
%      maintaining their italic shape (or whatever shape has
%      been specified for them) in case of the |italic|
%      option. Other math alphabet changing commands are
%      \cs{MathEulerBold}, \cs{MathEuler} and
%      \cs{MathPSymbol}. Note though that it is not possible
%      to use too many of such commands in the same
%      document, due to some limitations of
%      \LaTeX{}. Declaring them does not seem to be a
%      problem, and I will welcome any information by
%      knowledgeable people.
%
%    \item[math accents:]  an option |mathaccents| is
%    provided to pick up the accents in math mode from the
%    text font, but this is only for either an OT1-compatible or a
%    T1-encoded font.
%  
%    \end{description}
%
%    Regarding the encoding-dependent glyphs: the en-dash,
%    the dotless i and j, the math accents, the hbar, are
%    encoding dependent and the relevant decisions are made
%    by |mathastext| at the time it is loaded. So you can
%    use math versions with different encodings but,
%    regarding these characters only those with the same
%    encoding as the normal math version will display them
%    correctly. 
%
%  \section{Commands}    
%    
%    \subsection{Preamble-only commands}
%    Nothing is necessary besides loading |mathastext|, possibly
%    with some customizing options. The following commands provide
%    enhancements to the basic use of the package.
%    \begin{itemize}
%    \item |\Mathastext|: reinitializes |mathastext| according to the current
%      defaults of encoding, family, series and shape.
%      \begin{itemize}
%      \item It can also be preceded optionally by one or
%        more of\footnote{these commands exist also with
%        long names: \texttt{\char92Mathastextencoding},
%        etc\dots{} The same applies to the other commands
%        mentioned in this section.}
%      |\MTencoding|\marg{enc},
%        |\MTfamily|\marg{fam},
%        |\MTseries|\marg{ser},
%        |\MTshape|\marg{sh}, and, new with version
%        |1.1|, |\MTlettershape|\marg{sh}. For
%        example valid values are, respectively, \meta{T1},
%        \meta{phv}, \meta{m}, \meta{n}, and \meta{it}: this
%        is the Helvetica font in T1-encoding, regular
%        (medium) series, upright shape, and the letters
%        will be in italic shape.
%      \item with version |1.11| \cs{Mathastext} accepts an
%      optional argument, which will serve as a name to
%      designate the corresponding math version. Without
%      optional argument \cs{Mathastext} redefines the default
%      normal and bold versions. This argument, being
%      optional, must be enclosed within square brackets.
%      \end{itemize}
%      \item
%        |\MTWillUse|\oarg{ltsh}\marg{enc}\marg{fam}\marg{ser}\marg{sh}:
%        tells |mathastext| to use the font with the
%        specified encoding, family, series, and shape for
%        the letters and digits (and all other afflicted
%        characters) in math mode. The optional argument
%        \meta{ltsh} specifies a shape for the letters, for
%        example \cs{itdefault}, or directly \meta{it} or
%        \meta{sc}.
%      
%    \item
%      |\MTDeclareVersion|\oarg{ltsh}\marg{name}\marg{enc}\marg{fam}\marg{ser}\marg{sh}:
%      declares that the document will have access to the font
%      with the specified characteristics, under the version name
%      \meta{name}. For
%      example:\\
%      \hbox
%      to\hsize{\hss|\MTDeclareVersion[sc]{palatino}{T1}{ppl}{b}{sl}|\hss}
%      declares under the name |palatino| a version where
%      mathematics will be typset using the Palatino font in
%      T1-encoding, bold, slanted, and the letters will in fact be
%      in caps and small caps (and bold).\footnote{I do not
%      especially recommend to use this in real life!} When the
%      optional argument is absent, and |mathastext| was loaded
%      with the |italic| option, then the default letter shape
%      will be |it|,\footnote{more precisely, the shape is the
%      latest value passed in one of the previously used package
%      commands to specify the shape of letters, or the \cs{itdefault}
%      of the time of loading the package.}  else letters will
%      have the same shape as used for digits and operator-names.
%    \item |\MTboldvariant|\marg{var}: when used before |\Mathastext|,
%    specifies which bold
%      (|b|,|sb|,|bx|,\dots) to be used by \cs{mathbf} (and
%      \cs{boldmath}). Default is the \cs{bfdefault} at the time of
%      loading |mathastext|. When used before the declaration
%      of a version, decides the way \cs{mathbf} will act in this version.
%    \item |\MTEulerScale|\marg{factor}: scales the Euler font by
%      \meta{factor}.
%    \item |\MTSymbolScale|\marg{factor}: scales the Symbol font by
%      \meta{factor}.
%    \end{itemize}
%
%    \subsection{Body Text and Math commands}
%
%    \begin{itemize}
%    \item |\MTVersion|\oarg{nametext}\marg{namemath}: in
%      the absence of the optional argument changes
%      simultaneously (the behavior changed in version
%      |1.11|) the text and the math font to be the font
%      corresponding to the version \meta{namemath}. If
%      there is an optional argument then the text font will
%      use \meta{nametext} and the math mode will use \meta{namemath}. To
%      change only the math font, use the \LaTeX{} command
%      \cs{mathversion}.
%    \end{itemize}
%    All further commands are for math mode only.
%    \begin{itemize}
%    \item \cs{hbar}: this is constructed
%      (in a way compatible with the |italic| option) from
%      the |h| letter and the \={ } accent from the
%      |mathastext| font. Note that \cs{mathrm}|{\hbar}| and
%      \cs{mathbf}|{\hbar}| should work and that \cs{hbar}
%      does scale in subscripts and exponents. Only for T1
%      and OT1 encodings.
%    \item |\fouriervec|: this is a |\vec| accent taken from the Fourier font;
%    the |fourier| package need not be loaded. Active only
%    if option |fouriervec|.
%    \item |\pmvec|: this provides a poor man \cs{vec} accent command, for
%    upright letters. It uses the right arrow. Does not change
%    size in subscripts and exponents.
%    \item |\Mathnormal|, |\Mathrm|, |\Mathbf|: suitable modifications of the
%      original \cs{mathnormal}, \cs{mathrm}, \cs{mathbf}. By default, the
%      originals are also overwritten by the new commands.
%    \item |\mathnormalbold|: a bold version of \cs{mathnormal}.
%    \item |\inodot|, |\jnodot|: the corresponding glyphs in
%      the chosen font for math mode. By default, will
%      overwrite |\imath| and |\jmath|. With version |1.11|
%      by default |\i| and |\j| work also in math mode and
%      give then |\inodot|, resp. |\jnodot|. This should work for
%      all 8bit-encodings having these glyphs, and 
%      also in Unicode.
%    \item |\MathEuler|, |\MathEulerBold|: math alphabets to access
%    all the glyphs of the Euler font, if option |eulergreek| (or
%    |eulerdigits|) was passed to the package.
%    \item |\MathPSymbol|: math alphabet to access the Symbol font.
%    \item Capital Greek letters: macro names \cs{Digamma}, \cs{Alpha},
%      \cs{Beta}, \cs{Epsilon}, \cs{Zeta}, \cs{Eta}, \cs{Iota}, \cs{Kappa},
%      \cs{Mu}, \cs{Nu}, \cs{Omicron}, \cs{Rho}, \cs{Tau}, \cs{Chi} are
%      provided for the capital Greek letters which look like their Latin
%      counterparts. This is not done if the package detects that |\digamma|
%      is a defined macro, as then it is assumed that a suitable package has
%      been loaded for Greek letters. Also an \cs{omicron} control sequence is
%      provided.
%    \item Miscelleneous mathematical symbols from the
%      postscript Symbol font are made available (or
%      replaced) when option |symbolmisc| is passed. They
%      are \cs{prod}~$\prod$ \cs{sum}~$\sum$
%      \cs{implies}~$\implies$ \cs{impliedby}~$\impliedby$
%      \cs{iff}~$\iff$, \cs{shortiff}~$\shortiff$
%      \cs{to}~$\to$ \cs{longto}~$\longto$

%    \end{itemize}
%
%  \section{Complete list of options}
%
%  \begin{itemize}
%  \item |basic|: only mathastextify letters and digits.
%  \item |italic|: the letters will default to italic shape in
%  math mode.
% \item |frenchmath|: uppercase Latin letters in the same font as for digits
%   and operator names. In general this means that they will be upright.
%  \item |endash|, |emdash|: use the text font en-dash \textendash\ or even
%  the em-dash \textemdash\ (but this seems crazy) for the minus sign
%  rather than {}-{}. |endash| option is default for the package.
% \item |noendash|: the minus sign will be the - from the
% text font, not the en-dash \textendash.
% \item |nohbar|: prevents |mathastext| from defining its own
%   \cs{hbar}.
% \item |nolessnomore|: besides
%   !\,?\,*\,,\,.\,:\,;\,+\,-\,=\,(\,)\,[\,]\,/\,\#\,\$\,\%\,\&
%   |mathastext| treats also \DeleteShortVerb{\|}
%   $\mathord{<}\,\mathord{>}\,\mathord{|}$\, \{\,\} and
%   $\backslash$.\MakeShortVerb{\|} Use this option to not
%   do it. The option |nolessnomore| is activated by default
%   in case of OT1-encoding.
%  \item further excluding options: |noexclam|\ !\,?\
%    |noasterisk|\ *\ |nopunct|\ ,\,.\,:\,;\ |noplus|,
%    |nominus|, |noplusnominus|\ +\,\textendash{} |noequal|\ =\
%    |noparenthesis|\, (\,)\,[\,]\,/ \ |nospecials|\
%    \#\,\$\,\%\,\& and |nodigits|.
%  \item |alldelims|: true by default, means that the
%    characters excluded by |nolessnomore| are
%    treated. Use this option in case of a mono-width
%    OT1-encoded font.
%  \item |symbolgreek|, |symboldigits|: to let Greek letters (digits) use the
%    Symbol font.
%  \item |symbolre|: replaces \cs{Re} and \cs{Im} by the
%  Symbol glyphs $\Re, \Im$ and defines a
%    \cs{DotTriangle} command ($\DotTriangle$).
%  \item |symbolmisc|: takes quite a few glyphs, including logical arrows,
%    product and sum signs from Symbol. They are listed \emph{supra}.. You may
%    also consider \cs{renewcommand}|{\int}{\smallint}| to maximize still more
%    the use of the Symbol font.
%  \item |symboldelimiters|: the characters apart from
%  letters and digits will be taken from the Symbol font. 
%  \item |symbol|: combines |symbolgreek|, |symbolre|, and |symbolmisc|.
%  \item |symbolmax|: combines |symbol| and |symboldelimiters|.
%  \item |eulergreek|, |eulerdigits|: to let Greek letters (digits) use the
%    Euler font.
%  \item |selfGreek|: this is for a font which has the capital Greek
%    letters at the OT1 slot positions.
%  \item |mathaccents|: use the text font also for the math
%    accents. As in vanilla \LaTeX{}, they are taken from the font
%    for the digits and \cs{log}-like names. Obey the alphabet
%    changing commands. Will work only for T1 or OT1-compatible encodings.
%  \item |defaultrm|, |defaultbf|, |defaulnormal|: do not
%  overwrite the default \cs{mathrm}, \cs{mathbf}, \cs{mathnormal}.
%  \item |defaultimath|: do not overwrite \cs{imath} and
%  \cs{jmath}, do not extend \cs{i} and \cs{j} to math mode use.
%  \item |defaultmathsizes|: do not change the \LaTeX{} defaults.
%  \item |fouriervec|: provides a \cs{fouriervec} command.

% In the end, I moved the bold stuff to \cs{Mathastext} as the user may want
% his choice of |boldvariant| to have effect on the Euler font (it is
% possible to use \cs{Mathastextboldvariant}|{m}|). 
% 
% \LaTeXe{} has a strange initial configuration where the
% capital Greek letters are of type |mathalpha|, but the
% lower Greek letters of type |mathord|, so that \cs{mathbf}
% does not act on them, although lowercase Greek letters and
% Latin letters are from the same font. This is because
% \cs{mathbf} is set up to be like a bold version of
% \cs{mathrm}, and \cs{mathrm} uses the `operators' font, by
% default |cmr|, where there are no lowercase greek
% letters. This set-up is ok for the Capital Greek letters
% which are together with the Latin letters in both |cmmi|
% and |cmr|.
%
% The package eulervm sets also the lowercase Greek letters
% to be of type |mathalpha|, the default \cs{mathbf} and
% \cs{mathrm} will act wierdly on them, but a new
% \cs{mathbold} is defined which will use the bold series of
% the Euler roman font, it gives something coherent for
% Latin and Greek \emph{lowercase} letters, and this is
% possible because the same font contains upright forms for
% them all.
%
% Here in |mathastext|, Latin letters and Greek letters (lower and
% upper case) must be assumed to come from two different fonts, as
% a result the standard \cs{mathbf} (and \cs{mathrm}) will give
% weird results when used for Greek letters. It would be tricky
% but not impossible to coerce \cs{mathbf} to do something
% reasonable. I posted the method I have in mind to the texhax
% mailing list
% (|http://tug.org/pipermail/texhax/2011-January/016605.html|) but
% at this time |30-01-2011 09:42:27 CET| I decided I would not try
% to implement it here. I prefer to respect the default things.
%
