% This package enables the use of small capitals in different font
% shapes, e.g., slanted or bold slanted for all fonts that provide
% appropriate font shapes.
% The only prerequisite is that the corresponding |fd| file has to
% define the font shapes |scsl| resp.\ |scit| for slanted resp.\
% italic small capitals.

%
%
% \section{The user interface}
%
% To use this package place
% \begin{verbatim}
% \usepackage{slantsc}
% \end{verbatim}
% in the preamble of your document. No options are necessary.
%
% In \LaTeX, you can combine different font parameters like a bold
% series with an italic shape,
% \begin{verbatim}
% {\bfseries\itshape bold italic text}
% \end{verbatim}
% to get {\bfseries\itshape bold italic text}.
% But you are not able to combine two font shapes.
%
% Since \emph{italic, slanted,} and \emph{small caps} are shapes, you
% are not able write in {\slshape\scshape slanted small capitals}, for
% instance.
% This problem is avoided by the package |smallcap|, available from the
% \textsc{ctan} network, which redefines small caps to be a font
% family rather than a shape.
% But what to do if your font provides small capitals in roman style
% and in sans serifs?
% You are not able to access the sans serif version, then.
%
% The |slantsc| package has a different approach.
% It preserves small caps to be a font shape, but it enables to
% combine the small caps shape with the other shapes (upright, italic,
% slanted).
% \DescribeMacro{\upshape}%
% \DescribeMacro{\itshape}%
% \DescribeMacro{\slshape}%
% \DescribeMacro{\scshape}%
% Thus, you use the normal font shape switching commands
% \cs{upshape}, \cs{itshape}, \cs{slshape}, and \cs{scshape}.
% The first three commands act as usual among themselves.
% But if you use the \cs{scshape} command, it just adds the
% information "`small capitals"' to the current font shape.
%
% For example, if the current font shape is italic and you use
% \cs{scshape}, the following text is written in italic small
% capitals:
% \begin{verbatim}
%\itshape This is italic text, \scshape now additionally in Small Capitals.
% \end{verbatim}
% This leads to:
% \begin{quote}
% \itshape This is italic text, \scshape now additionally in Small
% Capitals.
% \end{quote}
% If you are in a small-capitals area, using one of the other font
% switching commands does not affect the small capitals status, but
% the rest of the font shape:
% \begin{verbatim}
%\itshape\scshape This is italic Small Capitals text, \upshape now Upright.
% \end{verbatim}
% This leads to:
% \begin{quote}
% \itshape\scshape This is italic Small Capitals text, \upshape now
% Upright.
% \end{quote}
%
% As usual, the change of font shape is terminated by the end of the
% group, e.g., by using braces:
% \begin{verbatim}
%\itshape This is italic {\scshape with Small Capitals} and without.
% \end{verbatim}
% This leads to:
% \begin{quote}
% \itshape This is italic {\scshape with Small Capitals} and without.
% \end{quote}
% Sometimes, you may want to switch off small capitals without using a
% group.
% \DescribeMacro{\noscshape}%
% To be able to do so, this package provides the \cs{noscshape}
% command, which works as follows:
% \begin{verbatim}
%\itshape This is italic \scshape with Small Capitals \noscshape and without.
% \end{verbatim}
% This leads to:
% \begin{quote}
% \itshape This is italic \scshape with Small Capitals \noscshape and without.
% \end{quote}
%
% \DescribeMacro{\textup}%
% \DescribeMacro{\textit}%
% \DescribeMacro{\textsl}%
% \DescribeMacro{\textsc}%
% \DescribeMacro{\emph}%
% Instead of the font switching commands you may also use the
% \cs{text}\ldots commands \cs{textup}, \cs{textit}, \cs{textsl},
% \cs{textsc} as well as the \cs{emph} command, e.g.
% \begin{verbatim}
%This is \emph{the person \textsc{Harald Harders} who wrote} this
%documentation.
% \end{verbatim}
% which leads to:
% \begin{quote}
% This is \emph{the person \textsc{Harald Harders} who wrote} this
% documentation.
% \end{quote}
%
% \DescribeMacro{\shapedefault}%
% \changes{2.00}{2003/09/17}{Describe \cs{shapedefault} command}%
% If you want another default font than the default, you may redefine
% the \cs{shapedefault} command.
% If you, for instance, want to use an italic small caps font as
% default font, you may simply use 
% \begin{verbatim}
% \renewcommand\shapedefault{\scdefault\itdefault}
% \end{verbatim}
% or
% \begin{verbatim}
% \renewcommand\shapedefault{\scitdefault}
% \end{verbatim}
% in the preamble of your document.
% Both variants are equivalent.
% Notice, that you have to use the command \cs{scdefault} before the
% other command for combined font shapes.
% If you want an upright small caps font as default, just use:
% \begin{verbatim}
% \renewcommand\shapedefault{\scdefault}
% \end{verbatim}
% You may not use \cs{scdefault}\cs{updefault} as argument!
% To switch to the default font, you may use the \cs{defaultfont}
% command.
%
% \DescribeMacro{\fontshape}%
% \changes{2.00}{2003/09/17}{Describe \cs{fontshape} command}%
% If you want to set the font shape directly, using the \cs{fontshape}
% command, e.g.:
% \begin{verbatim}
% \fontshape{\scdefault\itdefault}\selectfont
% \end{verbatim}
% The argument of this command is used in the same way as for the
% \cs{shapedefault} command.
%
%
% \section{Using other fonts than European Modern}
%
% This package works with all fonts that provide slanted and italic
% versions of the small capitals.\footnote{If bold versions are also
% available, they are of course also supported.}
% It is important that these font shapes are declared in a specific
% way that |slantsc| can find them.
%
% |slantsc| uses two additional font shapes |scsl| and |scit|
% which are slanted small caps and italic small caps,
% respectively.\footnote{In this section, I assume that you haven't
% redefined the default values for the different shapes. If you have
% done so, you have do adobt all strings according to your changes.}
% These font shapes have to be declared in the corresponding file with
% the file name \meta{encoding}\meta{font family}|.fd|, e.g.,
% |t1lmr.fd| for the Latin Modern fonts.
% For instance, the Latin Modern font family (version 0.86) provides
% slanted small capitals.
% The corresponding entry in the |fd| file looks like this:
% \begin{verbatim}
%\DeclareFontShape{T1}{lmr}{m}{scsl}%
%     {<-> cork-lmcsco10}{}
% \end{verbatim}
% This command declares to use the font |cork-lmcsco10| for the
% encoding |T1|, the font family |lmr|, the font series |m| (normal)
% and the font shape |scsl| (slanted small caps).
%
% Unfortunately, Latin Modern does not contain the bold variant of the
% slanted small caps.
% But if it had it, the entry would look like that:
% \begin{verbatim}
%\DeclareFontShape{T1}{lmr}{bx}{scsl}%
%     {<-> ...}{}
% \end{verbatim}
%
% Since nearly no font family will contain real italic small caps
% variants, the best approach is to substitute them by slanted
% variants.
% This could be done for Latin Modern by the following commands:
% \begin{verbatim}
%\DeclareFontShape{T1}{lmr}{m}{scit}{<->ssub * lmr/m/scsl}{}
%\DeclareFontShape{T1}{lmr}{bx}{scit}{<->ssub * lmr/bx/scsl}{}
% \end{verbatim}
%
% With the OT1 encoded Computer Modern fonts, slanted small capitals
% are not available, since these fonts do not contain them.
% Nevertheless, the font encoding is not forced to T1 by this package
% because it works with all encodings, if the font shapes are
% present.

% \changes{2.00}{2003/09/17}{Avoid using booleans because that causes
%   problems with explicit use of \cs{fontshape}}%
% Normally, using one of the font-shape commands \cs{upshape},
% \cs{slshape}, \cs{itshape}, and \cs{scshape} switches from one font
% shape to another, forgetting the old font shape.
% The new approach is switches only between \cs{upshape},
% \cs{slshape}, and \cs{itshape}.
% \cs{scshape} is ``added'' to the other font shape information.
% Thus, you are not able to use either of the commands \cs{upshape},
% \cs{slshape}, and \cs{itshape} to switch off small caps again.
% Therefor, you may use the command \cs{noscshape} which preserves the
% used font shape but moves from small caps to ordinary characters.
