+isomath.sty: Math layout for scientists
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

+
+Abstract
+========
+
+The isomath package enables formatting Greek and Latin letters as symbols
+for vectors, matrices, and tensors in the typefaces recommended for
+scientific papers by the International Standard ISO 31.
+
+
+Features
+========
+
+* Re-define Greek letters as \mathalpha, taking them from the "letters"
+  symbol fonts. 
+
+* The macros \vectorsym, \matrixsym, and \tensorsym select an
+  ISO-conforming typeface.
+    
+* For this, new math alphabets are defined:
+
+  \mathbold: for *boldface italic*  (vector and matrix symbols),
+  \mathsans: for *sans-serif italic* ,
+  \mathboldsans: for *sans-serif bold italic*  (tensor symbols).
+
+
+Requirements
+============
+
+This package builds on and extends fixmath.sty by Walter Schmidt.
+It also requires ifthen.sty and kvoptions.sty.
+
+The cmbright package is recommended for \mathsans and \mathboldsans
+matching with Computer Modern and derivatives.
+
+
+Installation
+============
+
+Copy isomath.sty to a suitable place in your TDS and make sure LaTeX can
+find it.
+
+Optionally, copy the documentation to a place where texdoc can find it.
+
+Usage
+=====
+ 
+* \usepackage{isomath}
+
+  In many cases (when \sfdefault expands to "cmss"), the \mathboldsans
+  alphabet is neither bold nor sans, as "cmss" has no OML encoded
+  variants and maps to "cmmi".
+
+* Use cmbright for the sans-serif math alphabets::
+
+  \usepackage[sfdefault=cmbr]{isomath}
+   
+* Redefine the standard \vec macro to typeset its argument in `bold
+  italic`::
+
+  \usepackage[sfdefault=cmbr]{isomath}
+  \renewcommand{\vec}{\vectorsym}
+
+* The mathdesign package comes with an OML encoded bold roman font but does
+  not use it for \mathbf in the default setting. With ::
+
+  \usepackage[charter]{mathdesign}
+  \usepackage[OMLmathbf,sfdefault=cmbr]{isomath}
+  
+  \mathbf{\pi} works as expected.

+\subsection{Math alphabets}
+
+The math alphabets should work with greek letters too (thus access
+to upright greek is possible for both, small and capital letters).
+If there are ligatures (ff, fi, ...) instead of small Greek letters
+in a math alphabet, it uses T1 or OT1 encoding instead of OML. \begin{eqnarray*}
+\mbox{mathnormal} &  & a,g,v,w,z,A,B,\Gamma,\Delta,E,\Theta,\Lambda,\Xi,\Pi,\Sigma,\Upsilon,\Phi,\Psi,\Omega,\alpha,\beta,\nu,\omega\\
+\mbox{mathit} &  & \mathit{a,g,v,w,z,A,B,\Gamma,\Delta,E,\Theta,\Lambda,\Xi,\Pi,\Sigma,\Upsilon,\Phi,\Psi,\Omega,\alpha,\beta,\nu,\omega}\\
+\mbox{mathrm} &  & \mathrm{\mathrm{a,g,v,w,z,A,B,\Gamma,\Delta,E,\Theta,\Lambda,\Xi,\Pi,\Sigma,\Upsilon,\Phi,\Psi,\Omega,\alpha,\beta,\nu,\omega}}\\
+\mbox{mathbf} &  & \mathbf{a,g,v,w,z,A,B,\Gamma,\Delta,E,\Theta,\Lambda,\Xi,\Pi,\Sigma,\Upsilon,\Phi,\Psi,\Omega,\alpha,\beta,\nu,\omega}\\
+\mbox{mathsf} &  & \mathsf{a,g,v,w,z,A,B,\Gamma,\Delta,E,\Theta,\Lambda,\Xi,\Pi,\Sigma,\Upsilon,\Phi,\Psi,\Omega,\alpha,\beta,\nu,\omega}\\
+\mbox{mathtt} &  & \mathtt{a,g,v,w,z,A,B,\Gamma,\Delta,E,\Theta,\Lambda,\Xi,\Pi,\Sigma,\Upsilon,\Phi,\Psi,\Omega,\alpha,\beta,\nu,\omega}
+\end{eqnarray*}
+ New alphabets are defined for italic-bold, italic-sans, and italic-sans-bold.
+\begin{eqnarray*}
+\mbox{mathbold}     &  &     \mathbold{a,g,v,w,z,A,B,\Gamma,\Delta,E,\Theta,\Lambda,\Xi,\Pi,\Sigma,\Upsilon,\Phi,\Psi,\Omega,\alpha,\beta,\nu,\omega}\\
+\mbox{mathsans}     &  &     \mathsans{a,g,v,w,z,A,B,\Gamma,\Delta,E,\Theta,\Lambda,\Xi,\Pi,\Sigma,\Upsilon,\Phi,\Psi,\Omega,\alpha,\beta,\nu,\omega}\\
+\mbox{mathboldsans} &  & \mathboldsans{a,g,v,w,z,A,B,\Gamma,\Delta,E,\Theta,\Lambda,\Xi,\Pi,\Sigma,\Upsilon,\Phi,\Psi,\Omega,\alpha,\beta,\nu,\omega}
+\end{eqnarray*}
+
+
+\subsection{Vector symbols}
+
+Symbols for vectors are boldface italic $\vec{\alpha}=\vec{e}_{1}\cdot\vec{a}$
+
+
+\subsection{Matrix symbols}
+
+Symbols for matrices are boldface italic, i. e. typeset in the same
+face as vectors:%
+\footnote{However, matrix symbols are usually capital letters whereas vectors
+are small ones. Exceptions are physical Quantities like the force
+vector $\vec{F}$ or the electrical field $\vec{E}$.%
+} $\matrixsym{\Gamma}=\matrixsym{E}\cdot\matrixsym{A}.$ 
+
+
+\subsection{Tensor symbols}
+
+Symbols for tensors are sans-serif bold italic, \begin{eqnarray*}
+\tensorsym{\alpha} & = & \tensorsym{e}\cdot\tensorsym{a}.\\
+\alpha_{ijl} & = & e_{ijk}\cdot a_{kl}\end{eqnarray*}
+
+
+The permittivity tensor describes the coupling of electric field and
+displacement: \[
+\vec{D}=\epsilon_{0}\tensorsym{\epsilon}_{\mathrm{r}}\vec{E}\]

+<h2><a class="toc-backref" href="#id19">OML font encoding</a></h2>
+<p>If a math alphabet shall support both, Greek and Latin letters, it must use
+the OML font encoding — no other established encoding provides Latin and
+Greek letters in one font:</p>
+<ul class="simple">
+<li>LGR is Greek-only,</li>
+<li>T7 is just a &quot;reserved name&quot; for a standard Greek encoding.</li>
+</ul>
+<p>The <cite>LaTeX font encodings</cite> guide <a class="citation-reference" href="#encguide" id="id6">[encguide]</a> defines:</p>
+<blockquote>
+The OML encoding contains italic Latin and Greek letters for use in
+mathematical formulas (typically used for variables) together with some
+symbols.</blockquote>
+<p>and names it <cite>TeX math italic</cite>. However, the reference to <em>italic</em> seems to
+be a description of the <em>state of the art</em> rather than a necessary
+restriction:</p>
+<ul class="simple">
+<li>The only OML encoded CM font is &quot;Computer Modern Math Italic&quot; (cmmi),</li>
+<li>but generally, font encodings (T1, OT1) are not specific to the font shape.</li>
+<li>Both, <tt class="docutils literal"><span class="pre">\DeclareSymbolFont</span></tt> and <tt class="docutils literal"><span class="pre">\DeclareMathAlphabet</span></tt> require a
+{&lt;shape&gt;} argument. Thus it is possible to define OML encoded math
+alphabets in roman {n} as well as italic {it} shape without conflicts.</li>
+<li>A more suitable public name would be <cite>TeX math letters</cite> or <cite>Original/Old
+Math Letters</cite>. The latter would also explain the acronym OML.</li>
+</ul>
+<p>Unfortunately, support for the OML encoding is missing for many font
+families even if the base font contains all Greek letters.
+Supported font families can be found searching for <tt class="docutils literal"><span class="pre">oml*.fd</span></tt> files and by
+grepping for &quot;DeclareFont.*OML&quot;, &quot;SymbolFont.*OML&quot; and &quot;MathAlphabet.*OML&quot;

+<h2><a class="toc-backref" href="#id20">Conclusions and outlook</a></h2>
+<p>It is hoped, that in the future more fonts families will support the OML
+encoding in normal and bold weight as well as upright and italic shape.
+This would be a major step towards the full support of the <a class="reference external" href="http://www.unicode.org/charts/PDF/U1D400.pdf">Mathematical
+Alphanumeric Symbols</a> Unicode block.</p>
+<p>This is (relatively) easy to achieve via virtual fonts when the glyphs for
+the Greek letters already exist (this is the case for many fonts where the
+primary version is Unicode encoded). Examples are Latin Modern, Kerkis,
+GFS-Neohellenic, LX-Fonts and KP-Serif.</p>
+<p>Alternatively, T7 could be used for math alphabets (if it ever happens to
+materialise).</p>
+<p>Upright small Greek letters in <tt class="docutils literal"><span class="pre">\mathrm</span></tt> would enable the specification of
+Myons, Pions, alpha-particles, photons, and neutrinos without special
+packages. (With <a class="reference external" href="http://dante.ctan.org/CTAN/help/Catalogue/entries/mathdesign.html">mathdesign</a>, this is already possible today.)</p>

+% :Abstract: The isomath package enables formatting Greek and Latin letters
+%            as symbols for vectors, matrices, and tensors in the typefaces
+%            recommended for scientific papers by the International
+%            Standard ISO 31.
+% 
+% .. contents:: 
+% 
+% Introduction
+% ************
+%             
+% Motivation
+% ==========
+% 
+% Scientific organisations like IUPAP_, IUPAC_, NIST_, BIPM_, and others
+% recommend typesetting math according to International Standard ISO 31
+% `Quantities and units`_ (ISO 31-0:1992 to ISO 31-14:1992).\ [#]_
+% 
+% .. [#] A summary of these rules is free available [typefaces]_. See also
+%        [symbol-fonts]_ and [SI-brochure]_.
+% 
+% The traditional `LaTeX-style` deviates in some points from this rules:
+% 
+% * The ``\vec`` command produces an array accent, while ISO 31 recommends
+%   a `bold italic` typeface for vector symbols.
+% 
+% * Greek letters are excluded from font changes with the math alphabets,
+%   while the ISO 31 rules apply equally to letters from both the Greek
+%   and the Latin alphabet.
+% 
+% * There is no provision for typesetting of Greek letters in `bold italic`
+%   style recommended for vectors (even though the required fonts are
+%   available).
+% 
+% * There is no provision for typesetting letters in `sans-serif bold italic`
+%   recommended for typesetting tensor symbols.
+% 
+% Some of these points are already adressed by `related packages`_, however
+% there is currently no package (known to the author) that defines the
+% *sans-serif bold italic* math alphabet needed for tensor symbols.
+% 
+% 
+% Features
+% ========
+% 
+% The ``isomath.sty`` package facilitates the task to abide with ISO 31 when
+% typesetting math with LaTeX:
+% 
+% * It utilises fixmath_ to re-define Greek letters as ``\mathalpha``, taking
+%   them from the "letters" symbol fonts (as opposed to "operators" in
+%   ``fontmath.ltx``). This ensures that
+% 
+%   + Greek letters change shape together with Latin letters if a different
+%     math alphabet is used.
+%     
+%   + Uppercase Greek letters are typeset in italic style by default.
+%   
+%   + Upright Greek letters are available through the ``\mathrm`` and
+%     ``\mathbf`` alphabets, if the corresponding fonts are OML encoded.
+% 
+% * The `command aliases`_ ``\vectorsym``, ``\matrixsym``, and ``\tensorsym``
+%   select an ISO-conforming typeface.
+%     
+% * For this, `new math alphabets`_ are defined:
+% 
+%   :``\mathbold``: for *boldface italic*  (vector and matrix
+%     symbols),
+% 
+%   :``\mathsans``: for *sans-serif italic* ,
+% 
+%   :``\mathboldsans``: for *sans-serif bold italic*  (tensor symbols).
+% 
+%   The family for these fonts is by default taken from the document's
+%   ``\rmdefault`` and ``\sfdefault`` values.  The ``rmdefault=<family>`` and
+%   ``sfdefault=<family>`` options_ can be used to override the defaults.
+% 
+% * `Font mappings`_ are defined for families which have an OML encoded
+%   counterpart but miss the substitution definition.
+% 
+% .. Now, it should be possible to typeset, e.g., the symbol for the tensor of
+%    dielectric permittivity ε according to the rules (i.e. sans-serif bold
+%    italic).
+% 
+% .. caution::  Using small Greek letters in a math alphabet command (e.g. 
+%    ``\mathrm{\pi}``) can lead to garbage. 
+%   
+%    You can use the `OML math*`_ options (if the used font supports the
+%    `OML font encoding`_) or place the Greek letter outside the math
+%    alphabet command. Some packages (including fixmath_) provide ``\up*``
+%    or ``\var*`` macros for upright Greek letters, e.g. 
+%    ``\mathrm{k}\upOmega``. 
+% 
+%    
+% Examples   
+% ========
+% 
+% * ``\usepackage{isomath}``
+% 
+%   In many cases (when ``\sfdefault`` expands to "cmss"), the
+%   ``\mathboldsans`` alphabet is neither bold nor sans, as "cmss" has no OML
+%   encoded variants and maps to "cmmi".
+% 
+% * Use cmbright_ for the sans-serif math alphabets::
+
+\usepackage[sfdefault=cmbr]{isomath}
+ 
+% * Redefine the standard ``\vec`` macro to typeset its argument in `bold
+%   italic`::
+
+%   \usepackage[sfdefault=cmbr]{isomath}
+%   \renewcommand{\vec}{\vectorsym}
+% 
+% * The mathdesign_ package comes with an OML encoded bold roman font but does
+%   not use it for ``\mathbf`` in the default setting. With ::
+
+%   \usepackage[charter]{mathdesign}
+%   \usepackage[OMLmathbf,sfdefault=cmbr]{isomath}
+%   
+%   ``\mathbf{\pi}`` works as expected.
+% 
+% Related packages
+% ================
+% 
+% Some packages already define Greek letters as ``\mathalpha`` and provide the
+% ``\mathbold`` alphabet (in OML):
+% 
+% * arev_     (Arev/Vera Sans)
+% * cmbright_ (CM Bright)
+% * eulervm_   (Euler Math)
+% * fixmath_  (Computer Modern)
+% * hvmath_   (HV-Math/Helvetica)
+% * mathpazo_ (Palatino)
+% * tmmath_   (TM-Math/Times)
+% 
+% This package builds on and extends fixmath_ by Walter Schmidt
+% (see Requirements_).
+% 
+% The cmbright_ package  provides fonts for ``\mathsans`` and
+% ``\mathboldsans`` matching with Computer Modern and derivatives.
+% 
+% Conflicts
+% ---------
+% 
+% The `fourier`_ package for math typesetting with Utopia defines its own,
+% incompatible math font encodings. It cannot be used with ``isomath`` but
+% provides other means to typeset upright or italic Greek (see its
+% documentation).
+% 
+% The `kpfonts`_, `pxfonts`_, and `txfonts`_ packages define many additional
+% math alphabets and can only be combined with ``isomath``, if the
+% reuseMathalphabets_ option is used.
+% 
+% OML font encoding
+% =================
+% 
+% If a math alphabet shall support both, Greek and Latin letters, it must use
+% the OML font encoding — no other established encoding provides Latin and
+% Greek letters in one font:
+% 
+% * LGR is Greek-only,
+% * T7 is just a "reserved name" for a standard Greek encoding.
+% 
+% The `LaTeX font encodings` guide [encguide]_ defines:
+% 
+%    The OML encoding contains italic Latin and Greek letters for use in
+%    mathematical formulas (typically used for variables) together with some
+%    symbols.
+% 
+% and names it `TeX math italic`. However, the reference to *italic* seems to
+% be a description of the *state of the art* rather than a necessary
+% restriction:
+% 
+% * The only OML encoded CM font is "Computer Modern Math Italic" (cmmi),
+% 
+% * but generally, font encodings (T1, OT1) are not specific to the font shape.
+% 
+% * Both, ``\DeclareSymbolFont`` and ``\DeclareMathAlphabet`` require a
+%   {<shape>} argument. Thus it is possible to define OML encoded math
+%   alphabets in roman {n} as well as italic {it} shape without conflicts.
+% 
+% * A more suitable public name would be `TeX math letters` or `Original/Old
+%   Math Letters`. The latter would also explain the acronym OML.
+% 
+% Unfortunately, support for the OML encoding is missing for many font
+% families even if the base font contains all Greek letters.
+% Supported font families can be found searching for ``oml*.fd`` files and by
+% grepping for "DeclareFont.*OML", "SymbolFont.*OML" and "MathAlphabet.*OML"
+% in ``*.sty`` files.

+% Explanations:
+% 
+% * If there is an alias (substitution) from the text font to a math-variant,
+%   only the text font is listed.
+% 
+% * Many text fonts define substitutions also for {n}, however mapping to
+%   an italic variant of the OML encoded font. These are not listed as
+%   supporting {m}{n} or {bx}{n} here.
+% 
+% The following fonts define ``cmm`` as OML substitution. A better matching
+% substitution can be set with the rmdefault_ option.

+% 
+% Conclusions and outlook
+% =======================
+% 
+% It is hoped, that in the future more fonts families will support the OML
+% encoding in normal and bold weight as well as upright and italic shape.
+% This would be a major step towards the full support of the `Mathematical
+% Alphanumeric Symbols`_ Unicode block.
+% 
+% This is (relatively) easy to achieve via virtual fonts when the glyphs for
+% the Greek letters already exist (this is the case for many fonts where the
+% primary version is Unicode encoded). Examples are Latin Modern, Kerkis,
+% GFS-Neohellenic, LX-Fonts and KP-Serif.
+% 
+% Alternatively, T7 could be used for math alphabets (if it ever happens to
+% materialise).
+% 
+% Upright small Greek letters in ``\mathrm`` would enable the specification of
+% Myons, Pions, alpha-particles, photons, and neutrinos without special
+% packages. (With mathdesign_, this is already possible today.)

+% Implementation
+% **************
+% 
+% Identification
+% ==============
+% ::
+
+\NeedsTeXFormat{LaTeX2e}
+\ProvidesPackage{isomath}
+[2008/06/23 v0.1 typeset math according to International Standard ISO 31]
+
+% Requirements
+% ============
+% 
+% fixmath
+% -------
+% 
+% fixmath_ by Walter Schmidt defines Greek letters as symbols of type
+% ``\mathalpha`` and takes them from the "letters" SymbolFont in
+% ``\mathnormal``. (It also defines the ``\mathbold`` alphabet, setting it to
+% ``cmm``. This definition will be overwritten with a configurable value for
+% the font family below.) 
+% ::
+
+\RequirePackage{fixmath}
+
+% ifthen
+% ------
+% 
+% The standard LaTeX package `ifthen`_ provides the commands ``\ifthenelse``,
+% and ``\whiledo``. ::
+
+\RequirePackage{ifthen}
+
+% kvoptions
+% ---------
+% 
+% The kvoptions_ package in the oberdiek_ bundle facilitates the setup of
+% package options and provides a key=value interface (based on keyval_)::
+
+\RequirePackage{kvoptions}
+
+% Options
+% =======
+% 
+% rmdefault
+% ---------
+% 
+% Alternative math font family name for roman. The default is to use the
+% corresponding text font family (``\rmdefault``) in OMS encoding.
+% `Table 2`_ lists some fonts where a different setting is advised.
+% ::
+
+\DeclareStringOption[\rmdefault]{rmdefault}
+
+% sfdefault
+% ---------
+% 
+% Alternative math font family name for sans-serif. The default is to use the
+% corresponding text font family (``\sfdefault``) in OMS encoding.
+%  
+% Computer Modern Sans Serif (cmss) has no italic and bold variants in OMS
+% encoding. Nor have many derivatives (lmss, aess, ...).
+% Actually, there are only a few OML-encoded sans-serif fonts (all
+% slanted/italic):
+% 
+% :zavm:  arev_ (Vera Sans with math extension)
+% :cmbr:  cmbright_ (Computer Modern Bright, slightly lighter than cmss)
+% :iwona: iwona_ (Humanistic Sans Serif)
+% :hvm:   hvmath_ (Helvetica Math, commercial, free bitmap version)
+% :llcmm: lxfonts_ (LX Fonts, very wide and quite eccentric, new in 2008)
+% 
+% For many fonts (especially CM and related), ``[sfdefault=cmbr]`` is the
+% recommended setting.
+% 
+% ::
+
+\DeclareStringOption[\sfdefault]{sfdefault}
+
+
+% reuseMathalphabets
+% ------------------
+% 
+% The definition of `new math alphabets`_ can lead to a "too many math
+% alphabets used in version normal" error.
+% 
+% As a workaround, this option tells ``isomath`` to re-use the existing
+% ``\mathbf`` and ``\mathsf`` alphabets for italic bold and sans-serif.
+% 
+% To access the upright shapes, the corresponding ``\textbf`` and ``\textsf``
+% command can be used (remember that this toggles the math-mode off and might
+% use a different font). 
+% 
+% Both standard and `new math alphabets`_ are in upright shape, if this option
+% is combined with the corresponding `OML math*`_ option. 
+% ::
+
+\DeclareBoolOption{reuseMathalphabets}
+
+% OML math*
+% ---------
+% 
+% These options cause isomath to `redefine standard alphabets`_ in OML
+% encoding.
+% 
+% With Greek letters defined as ``\mathalpha``, the math alphabets are
+% expected to be in `OML font encoding`_. OT1 encoded fonts have ligatures and
+% non-alpha symbols in place of the small Greek letters.
+% 
+% Setting these options enables access to small Greek letters in different
+% shapes with e.g. ``\mathrm{\pi}``. 
+% Currently, support for the `OML font encoding`_ is rather limited:
+% 
+% * only the mathdesign_ fonts support *bold roman* in OML encoding, while
+% * many font packages define an italic font as OML replacement for a roman
+%   font.
+%   
+% With some packages, these options can result in a "too many math alphabets
+% used in version normal" error.

+\ProcessKeyvalOptions*
+
+% Declarations
+% ============
+% 
+% New math alphabets
+% ------------------
+% 
+% The `italic bold` math alphabet is named ``\mathbold`` in `related
+% packages`_. For letters, this is the same as the bold version of
+% ``\mathnormal``. With the reuseMathalphabets_ option, ``\mathfb`` is
+% redefined and ``\mathbold`` made an alias (overwriting existing
+% definitions). ::
+
+\ifthenelse{\boolean{isomath@reuseMathalphabets}}
+{
+  \DeclareMathAlphabet{\mathbf}{OML}{\isomath@rmdefault}{bx}{it}
+  \def\mathbold{\mathbf}
+}
+{
+  \DeclareMathAlphabet{\mathbold}{OML}{\isomath@rmdefault}{bx}{it}
+}
+
+% For `italic sans-serif`, we either redefine ``\mathsf`` (with
+% reuseMathalphabets_) or, in analogy to ``\mathbold``, we define the new
+% alphabet ``\mathsans``::
+
+\ifthenelse{\boolean{isomath@reuseMathalphabets}}
+{
+  \DeclareMathAlphabet{\mathsf}{OML}{\isomath@sfdefault}{m}{it}
+  \def\mathsans{\mathsf}
+}
+{
+  \DeclareMathAlphabet{\mathsans}{OML}{\isomath@sfdefault}{m}{it}
+}
+
+% A `sans serif slanted bold` alphabet is needed for the tensor
+% symbols. As there is no standard math alphabet to re-use, we define the new
+% alphabet ``\mathboldsans``::
+
+\DeclareMathAlphabet{\mathboldsans}{OML}{\isomath@sfdefault}{bx}{it}
+
+
+% Redefine standard alphabets
+% ---------------------------
+% 
+% Redefine standard alphabets in `OML font encoding`_
+% (if the corresponding `OML math*`_ option is true). ::
+
+\ifthenelse{\boolean{isomath@OMLmathrm}}
+{\SetMathAlphabet{\mathrm}{normal}{OML}{\isomath@rmdefault}{n}{n}}{}
+\ifthenelse{\boolean{isomath@OMLmathbf}}
+{\SetMathAlphabet{\mathbf}{normal}{OML}{\isomath@rmdefault}{b}{n}}{}
+\ifthenelse{\boolean{isomath@OMLmathbf}}
+{\SetMathAlphabet{\mathsf}{normal}{OML}{\isomath@sfdefault}{n}{n}}{}
+\ifthenelse{\boolean{isomath@OMLmathtt}}
+{\SetMathAlphabet{\mathtt}{normal}{OML}{\ttdefault}{n}{n}}{}
+
+% Command aliases
+% ---------------
+% 
+% Define commands to typeset some symbol categories complying to
+% the ISO standard.
+% 
+% Vector symbols
+% """"""""""""""
+% 
+% Symbols for vectors are *boldface italic*::
+
+\newcommand{\vectorsym}{\mathbold}
+
+% For easier writing or to make existing documents conform to the standard,
+% you might want to re-define the standard ``\vec`` command after loading this
+% package (cf. the Examples_ section).
+% 
+% Matrix symbols
+% """"""""""""""
+% 
+% Symbols for matrices are *boldface italic*, i. e. typeset in the same face as
+% vectors (see [typefaces]_). [#]_ ::
+
+\newcommand{\matrixsym}{\mathbold}
+
+% .. [#] However, matrix symbols are usually capital letters whereas vectors
+%        are small ones. Exceptions are physical Quantities like the force
+%        vector F or the electrical field E.
+% 
+% Tensor symbols
+% """"""""""""""
+% 
+% Symbols for tensors are *sans-serif bold italic*::
+
+\newcommand{\tensorsym}{\mathboldsans}
+
+% Font mappings
+% -------------
+% 
+% Some font packages provide a matching math font but do not define a
+% substitution in their ``*.fd`` files.
+% 
+% We define the substitutions needed for the math alphabet definitions in this
+% package. Ideally, these should become part of a more complete set of
+% definitions in the package's fd file(s):
+% 
+% Mathpazo (Palatino) ppl -> zplm ::
+
+\DeclareFontFamily{OML}{ppl}{\skewchar\font127}
+\DeclareFontShape{OML}{ppl}{m}{it}{<-> ssub * zplm/m/it}{}
+\DeclareFontShape{OML}{ppl}{bx}{it}{<-> ssub * zplm/b/it}{}
+
+% Arev (arev): fav -> zavm ::
+
+\DeclareFontFamily{OML}{fav}{}
+\DeclareFontShape{OML}{fav}{m}{it}{<->ssub * zavm/m/it}{}
+\DeclareFontShape{OML}{fav}{bx}{it}{<->ssub * zavm/b/it}{}
+
+% LX Fonts (lxfonts): llcmss -> llcmm ::
+
+\DeclareFontFamily{OML}{llcmss}{}
+\DeclareFontShape{OML}{llcmss}{m}{it}{<-> ssub * llcmm/m/it}{}
+\DeclareFontShape{OML}{llcmss}{bx}{it}{<-> ssub * llcmm/bx/it}{}
+
+% The end
+% =======
+% ::
+
+\endinput
+
+% TODO
+% ====
+% 
+% The ``\mathsans`` definition "increases symmetry". However, it adds a math
+% alphabet that is rarely (or not at all) used. Giving the limit of 16 math
+% alphabets, it might be better not to define it. Make it an option?
