-README for the `xfrac' package.
-
-The `xfrac' package is designed for production of split level
-fractions in LaTeX2e*. Yes that's right: there is indeed a star in
-the LaTeX version. It is very much a prototype implementation
-intended for future use, so you'll need an up-to-date (at least at
-the time of writing) LaTeX setup.
-
-Dependencies are:
- e-TeX extensions needed in the LaTeX format
- LaTeX release of 2003/12/01
- The LaTeX2e* package `template'
- The experimental package `xparse'
-
-The last two of these dependencies can be downloaded as part of
-the `xbase' bundle from
- http://www.latex-project.org/code/experimental/
-
-Documentation dependencies are
- The `nicefrac' package (part of the `units' bundle)
- The `eco' package and its virtual fonts.
-
-These two are just to illustrate problems often seen when not
-using an advanced approach such as `xfrac'.

-% \section{A Bit of History}
-%
-% \subsection{The Past}
-%
-% One of the first exercises in \emph{The \TeX Book} is to design a
-% macro for split level fractions. The solution shows a level of
-% simplicity only rivaled by its fundamental design flaws: It can
-% only be used when the text font and the math font are the same and
-% worse still it uses a \emph{virgule} (a slash) for separating the
-% two components. The proper symbol for that is a \emph{solidus}
-% which sadly is absent from Computer Modern. It is however
-% available in the European Computer Modern fonts, but I'll get back
-% to that.
-%
-% \subsection{The Present}
-%
-% So how does people produce split level fractions nowadays? The
-% answer is that they use the \package{nicefrac} package. For text
-% it gives you \nicefrac{1}{2}, while the built-in
-% \package{textcomp} symbol is \textonehalf. Hmmm, bad example due
-% to the strange design of the EC fonts. Lets try Palatino instead.
-% Then |\nicefrac{1}{2}| produces \switch{ppl}{\nicefrac{1}{2}}
-% while the built-in symbol is \switch{ppl}{\textonehalf}, and it's
-% plain to see the problems; a)~it uses the virgule instead of the
-% solidus and b)~the font size of the numerator and the denominator
-% is bigger than in the built-in symbol. We'll have to take care of
-% this somehow.
-%
-% Another problem arises when the font has old style figures as the
-% \package{eco} package provides for Computer Modern. Here we get
-% results like \switch{cmor}{\nicefrac{1}{2}} and
-% \switch{cmor}{\nicefrac{8}{9}}. We'll have to do better than that.
-%
-% That was text mode. I wonder what happens in math mode?
-% \begin{verbatim}
-% \[
-% \mathbf{ 2 \times \nicefrac{1}{2} }
-% \times \mathit{2\times \nicefrac{1}{2}}
-% \]
-% \end{verbatim}
-% \[
-% \mathbf{ 2 \times \nicefrac{1}{2} }
-% \times \mathit{2\times \nicefrac{1}{2}}
-% \]
-% Whoops! Didn't see that coming, did you? I certainly didn't.
-%
-%
-% This section sounds very much like me tearing the
-% \package{nicefrac} package apart and well, yes, that's precisely
-% what I'm doing. It \emph{is} simple and it \emph{does} produce
-% somewhat acceptable results for Computer Modern, but if we want a
-% single package for producing such fractions we need a radical new
-% approach.
-%
-%
-%
-%
-% \subsection{The Future}
-%
-% Fonts are wildly different; one macro that works fine for Computer
-% Modern obviously doesn't work well at all in Palatino. For one we
-% have to make the separator symbol configurable, and we need to
-% take care of several details as well: font scaling of the
-% numerator/denominator pair (ND), font selection of ND etc. If we
-% are to have a single package for this in the future\footnote{As
-% this is intended to be about the future, the \package{xfrac} package
-% requires the \eTeX{} extensions.} we have to define a totally
-% generic interface for the fraction commands and then adjust
-% parameters depending on the current font. What you see in this
-% prototype implementation of \package{xfrac} is just that.
-%
-%
-% \section{The User Interface}
-%
-% The \package{xfrac} package defines a document command \cs{sfrac}
-% with the following syntax:
-% \begin{quote}
-% \cs{sfrac}\oarg{instance}\marg{num}\oarg{sep}\marg{denom}
-% \end{quote}
-% Lets show a few examples:
-% \begin{verbatim}
-% \sfrac{1}{2}, $\sfrac{1}{2}$,
-% $\mathbf{3\times\sfrac{1}{2}}$
-% \quad \fontfamily{ppl}\selectfont Palatino: \sfrac{1}{2}
-% \quad \fontfamily{ptm}\selectfont Times: \sfrac{1}{2}
-% \end{verbatim}
-% \begin{quote}
-% \sfrac{1}{2}, $\sfrac{1}{2}$, $\mathbf{3\times\sfrac{1}{2}}$
-% \quad \fontfamily{ppl}\selectfont Palatino: \sfrac{1}{2}
-% \quad \fontfamily{ptm}\selectfont Times: \sfrac{1}{2}
-% \end{quote}
-% You'll notice something interesting: Not only does the \cs{sfrac}
-% command work as it should in math mode, it also gets the job done
-% for other fonts as well.
-%
-% \subsection{Text mode}
-%
-% The usual problem in text mode has a name: Computer Modern. The
-% solidi of all the Computer Modern fonts leave a lot to be desired,
-% although things are potentially looking better as the Latin Modern
-% fonts are becoming more stable and widespread. As long as the
-% default fonts are Computer Modern variants we must however work
-% around this. One idea that comes to mind is to see what happens
-% when you use a solidus from another font instead. Lets try with
-% Times:
-% \begin{quote}
-% \DeclareInstance{xfrac}{cmr2}{text}{
-% slash-symbol-font = ptm,
-% }
-% ``You take \sfrac[cmr2]{1}{2} cup of sugar, \ldots''
-% \end{quote}
-% That looks quite good actually, so it was probably very difficult
-% to obtain that result. Nope, it was extremely easy---if you happen
-% to know about \emph{instances}:
-% \begin{verbatim}
-% \DeclareInstance{xfrac}{cmr}{text}{
-% slash-symbol-font = ptm,
-% }
-% \end{verbatim}
-% So we define an instance with the name `cmr' from the template
-% `text' which in turn is of template type `xfrac'. You'll notice
-% the `cmr' is also the name of the font family for Computer Modern
-% Roman and the reasoning behind is that every font family should
-% have it's own settings, and if a document command is to work well
-% in that scheme, letting it use the name of the current font family
-% seems like a good idea. Thus the \cs{sfrac} command checks to see
-% whether an instance with same name as the current font family
-% exists and uses it if the test is true; otherwise the default
-% setting is used. Here we defined the instance to be used for the
-% font family `cmr' and just told it to use the Times font for
-% typesetting the slash symbol which turns out to be a solidus by
-% default.
-%
-% The option \texttt{cm-recommended} which is loaded by default uses
-% the Times solidus for Computer Modern Roman and Computer Modern
-% Sans Serif and the Palatino solidus for Computer Modern Typewriter
-% Type. This looks quite good. Should you however not want this you
-% can use the option \texttt{cm-standard} which produces somewhat
-% acceptable results using Computer Modern exclusively.
-%
-% So what about old style figures? If you use the \package{eco}
-% package you might define an instance similar to this (`cmor' is
-% the name of the roman font activated by \package{eco}):
-% \DeclareInstance{xfrac}{cmor}{text}{
-% slash-symbol-font = ptm,
-% numerator-font = cmr,
-% denominator-font = cmr,
-% }
-% \begin{verbatim}
-% \DeclareInstance{xfrac}{cmor}{text}{
-% slash-symbol-font = ptm,
-% numerator-font = cmr,
-% denominator-font = cmr,
-% }
-% \end{verbatim}
-% We also use regular Computer Modern Roman for typesetting ND, so
-% we end up with \switch{cmor}{\sfrac{1}{2}} and
-% \switch{cmor}{\sfrac{8}{9}} instead of
-% \switch{cmor}{\nicefrac{1}{2}} and \switch{cmor}{\nicefrac{8}{9}}.
-% Much better.
-%
-% There are also situations where other tricks are useful. If you
-% don't have the inferior and superior figures available in a font,
-% or the font doesn't have a wider design for small font sizes, you
-% can cheat by manually scaling the ND-pair. I got nice results for
-% Adobe's Stempel Garamond (with small caps and old style figures)
-% with the following setup:
-% \begin{verbatim}
-% \DeclareInstance{xfrac}{pegj}{text}{
-% numerator-font = pegx,
-% denominator-font = pegx,
-% scale-factor = .9,
-% h-scale = 1.1,
-% }
-% \end{verbatim}
-% We use the font family `pegx' (Stempel Garamond with real small
-% caps) for typesetting the ND-pair. Additionally the key
-% \key{scale-factor} specifies that the font size used for the
-% ND-pair should be $0.9$ of the height of the solidus, and the key
-% \key{h-scale} specifies that the ND-pair should be scaled an extra
-% 10\% horizontally.
-%
-% Should you be so fortunate the have a font with inferior and
-% superior figures like in the Monotype Janson example from Philipp
-% Lehman's excellent \emph{The Font Installation Guide}. In that
-% example Philipp defines the font families `mjn0' for the inferior
-% figures and `mjn1' for the superior. Thus to get the \cs{sfrac}
-% command to use them on the fly for the font family `mjnj' (Janson,
-% old style figures) we would say
-% \begin{verbatim}
-% \DeclareInstance{xfrac}{mjnj}{text}{
-% numerator-font = mjn1,
-% denominator-font = mjn0,
-% scaling = false,
-% numerator-bot-sep = 0pt,
-% denominator-bot-sep = 0pt,
-% }
-% \end{verbatim}
-% I think this example is a very clean way to do it. An alternative
-% approach could be to use the keys \key{numerator-format} and
-% \key{denominator-format} to process the arguments and let them
-% determine what to do.
-%
-% As a side note Harald Harders was so kind to test it, and it
-% \emph{does} actually work---I hadn't tested it myself.
-%
-% \subsection{Math Mode}
-%
-% In math mode the choices are a lot fewer because first of all
-% \TeX{} comes with a built-in limitation of 16 math families.
-% Additionally we will not need a solidus for typesetting split
-% fractions in math, as tradition is to use a virgule instead. We
-% define the basic `mathdefault' instance to simply use the math
-% family in use when the instance is run. So if we're in normal math
-% like |$\sfrac{7}{9}$| we simply get family~$-1$. If we're inside a
-% \cs{mathbf} we're in family~$4$ (in the standard setup at least),
-% and so the fraction is typeset with the same math family. Simple,
-% isn't?
-%
-% You can also declare instances for the math families, but I really
-% don't see why you would. If you do then name them according to the
-% scheme `mathfam\meta{N}', where \meta{N} is the family number, and
-% only do it if you \emph{really} know how to set up math fonts.
-% That is, if \cs{DeclareMathAlphabet} is unbeknownst to you, then
-% just don't go there.
-%
-%
-% Another example: If we want \cs{sfrac} to produce split fractions
-% without doing anything at all, we can choose the collection
-% `plainmath', which is defined as
-% \begin{verbatim}
-% \DeclareCollectionInstance{plainmath}{xfrac}{mathdefault}{math}{
-% denominator-bot-sep = 0pt,
-% numerator-bot-sep = 0pt,
-% numerator-top-sep = \maxdimen,
-% scaling = false,
-% slash-right-mkern = 0mu,
-% slash-left-mkern = 0mu,
-% }
-% \end{verbatim}
-% This creates an alternative version of the instance `mathdefault'
-% with settings as specified by the keys. In the default math setup
-% \key{numerator-top-sep} is set to 0~pt, and here we set
-% \key{numerator-bot-sep} to 0~pt as well, so in order to avoid
-% over-specification (and an error message) we must set
-% \key{numerator-top-sep} to \cs{maxdimen}. We activate (obeying
-% normal scoping rules) it with:
-% \begin{verbatim}
-% \UseCollection{xfrac}{plainmath}
-% \end{verbatim}
-% Then |$\sfrac{8}{13}$| produces\begingroup
-% \UseCollection{xfrac}{plainmath}
-% $\sfrac{8}{13}$ and just typing |$8/13$| gives the same result:
-% $8/13$.
