-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:
-%    $8/13$.

-%
-%  We set up the programming interface. We need the

-%  experimental code, more precisely from the `xbase' bundle. The
-%  other packages are well-known.
-%    \begin{macrocode}

-%  \changes{v0.10b}{2004/04/07}{Now uses \cs{InternalSyntaxOn}} With
-%  v0.10b I introduced the new internal syntax using |_| and |:|.

-%  It also has an optional argument that comes before the first
-%  mandatory argument. If used it will use that instance instead of
-%  the auto-detected one, so a user who has defined the instance
-%  `cmr2' may use
-%  \begin{verbatim}
-%    \sfrac[cmr2]{7}{12}
-%  \end{verbatim}
-%  and get the settings from `cmr2' instead of the settings of the
-%  current font family.
-%    \begin{macrocode}
