%   The \pkg{fontaxes} package simulates multiple independent font selection
%   axes on top of certain single \acro{NFSS} axes: \axis{base family},
%   \axis{figure style}, and \axis{figure alignment} on top of \axis{family};
%   \axis{primary shape} and \axis{secondary shape} on top of \axis{shape};
%   and \axis{math weight} and \axis{math figure alignment} on top of

% \section{Introduction}
%
% The introduction of the New Font Selection Scheme (\acro{NFSS}) has
% greatly simplified the usage of \LaTeX\ with fonts different from the
% Computer Modern fonts originally designed for \TeX. However, the \acro{NFSS}
% has some limitations. In particular, it~defines only one axis for the font
% shape, which caters for both the actual \emph{shape} of the font (e.g.\
% upright, italic or slanted) and the \emph{case} of the font (e.g.\
% upper-lower case and small-caps). For example, if the current font shape is
% italic, then selecting small capitals using |\scshape| or |\textsc| will
% revert to an upright shape, even if the font has italic small capitals.
%
% The \pkg{fontaxes} package alleviates the deficiencies of the \acro{NFSS}
% by simulating multiple axes on top of single \acro{NFSS} axes. In particular,
% it replaces the single \acro{NFSS} shape axis by a primary and a secondary
% shape axis, catering for the shape and the case of the font, respectively.
% Moreover, the package introduces three new axes to deal
% with different \emph{figure versions}, which are provided by many
% professional fonts.
%
% \section{Usage}
%
% You can load this package by adding
% \begin{quote}
%   |\usepackage{fontaxes}|
% \end{quote}
% to the preamble of your document. This redefines and makes available
% certain font selection commands, which are described in the rest of
% this section.
%
% \subsection{Shape}
%
% The \pkg{fontaxes} package splits the \acro{NFSS}'s single shape axis into
% two: the primary shape axis (|n|, |it|, etc.) and the secondary shape axis
% (|ulc|, |sc|, etc.).
%
% \DescribeMacro\upshape %
% \DescribeMacro\itshape %
% \DescribeMacro\slshape %
% \DescribeMacro\swshape %
% The commands |\upshape|, |\itshape|, and |\slshape| are redefined
% to access the primary axis only. For access to a swash shape, the command
% |\swshape| has been added.
%
% \DescribeMacro\ulcshape %
% \DescribeMacro\scshape %
% \DescribeMacro\sscshape %
% The commands |\scshape| and |\sscshape| (spaced small caps) access the
% secondary axis. To return from any small-caps shape to upper-lower case,
% you can use the command |\ulcshape|.
%
% \DescribeMacro\fontprimaryshape %
% \DescribeMacro\fontsecondaryshape %
% All these commands update the two shape axes using the low-level commands
% |\fontprimaryshape|\marg{value} and |\fontsecondaryshape|\marg{value}.
%
% \DescribeMacro\swdefault %
% \DescribeMacro\sscdefault %
% \DescribeMacro\ulcdefault %
% If you want to change which values are used by the various commands
% |\|\meta{abbr}|shape|, redefine the corresponding |\|\meta{abbr}|default|.
% The additional commands |\swdefault|, |\sscdefault|, and |\ulcdefault| are
% provided with their default values |sw|, |ssc|, and |ulc|, respectively.
%
% \subsection{Figure version}
%
% Different figure versions are usually implemented as different font families
% (e.g.\ |MinionPro-{OsF,LF,TOsF,TLF}| or |ppl{j,x}|).
% The \pkg{fontaxes} package splits off the axes \axis{figure style} and
% \axis{figure alignment}, which leaves the \axis{base family} (e.g.\ 
% |MinionPro| or |ppl|).\pagebreak
%
% \changes{v0.2}{2005/05/04}{Rename figures switching commands
%   |\|\meta{\dots}|fig|.}
% \DescribeMacro\txfigures %
% \DescribeMacro\lnfigures %
% \DescribeMacro\tbfigures %
% \DescribeMacro\prfigures %
% The \pkg{fontaxes} package knows two figure styles, |text| and |lining|
% (accessible via |\txfigures| and |\lnfigures|), and two modes of figure
% alignment, |tabular| and |proportional| (accessible via the switches
% |\tbfigures| and |\prfigures|).
%
% \DescribeMacro\fontfigurestyle %
% \DescribeMacro\fontfigurealignment %
% Additionally, you can access both axes directly using the low-level commands
% |\fontfigurestyle|\marg{value} and |\fontfigurealignment|\marg{value}.
%
% \DescribeMacro\fontbasefamily %
% If you want to change the font family without changing the figure version,
% use |\fontbasefamily|\marg{value}. (All |\font|\dots\ commands
% require a successive |\selectfont| to make the changes take effect.)
%
% For choosing the figure versions to be used in math mode, you can use the
% corresponding axis \axis{math figure alignment}. Note that there is
% currently no means for changing the figure style used in math.
%
% \subsection{Math version}
%
% \DescribeMacro\boldmath %
% \DescribeMacro\unboldmath %
% By default, \LaTeX\ provides two math versions, |normal| and |bold|, as well
% as commands |\boldmath| and |\unboldmath| for switching between them. The
% \pkg{fontaxes} packages redefines these commands to operate on the axis
% \axis{math weight}.
%
% \DescribeMacro\tabularmath %
% \DescribeMacro\proportionalmath %
% A second axis \axis{math figure alignment} is introduced that allows you to
% switch between |tabular| and |proportional| figures using |\tabularmath| and
% |\proportionalmath|. (This assumes the presence of additional math versions
% |tabular| and |boldtabular|; the package will copy the setups of math
% versions |normal| and |bold| at the end of the preamble in case you do not
% provide your own declarations.)
%
% \DescribeMacro\mathweight %
% \DescribeMacro\mathfigurealignment %
% You can directly assign values to the axes using the low-level commands
% |\mathweight|\marg{value} and |\mathfigurealignment|\marg{value}.
%
% Table~\ref{tab:cmds} summarizes which commands set which values on which
% axes.\par

% \DescribeMacro\textfigures %
% \DescribeMacro\liningfigures %
% \DescribeMacro\tabularfigures %
% \DescribeMacro\proportionalfigures %
% Similar to the well-known |\textit|, |\textsc|, etc.\ this package provides
% commands |\textsw|, |\textssc|, |\textulc|, |\textfigures|, |\liningfigures|,
% |\tabularfigures| and |\proportionalfigures| that take one argument and
% apply the font change only to the argument.
% For example, |\textsw|\marg{text} is roughly equivalent to
% |{\swshape|\meta{text}|}| (but automatically adds italic corrections).
%
% \DescribeMacro\figureversion %
% The command |\figureversion|\marg{options} allows easy switching of multiple
% aspects of figures simultaneously. It takes as an argument a comma-separated
% list of one or more of the following options:
% \begin{quote}
% \begin{tabular}{@{}ll}
% |text|, |osf| & for text figures,\\
% |lining|, |lf| & for lining figures,\\
% |tabular|, |tab| & for tabular figures,\\
% |proportional|, |prop| & for proportional figures.
% \end{tabular}
% \end{quote}
% For example, |\figureversion{lf,tab}| selects tabular lining figures.
