%
% \begin{abstract}
% A \TeX\ format file may include alternative hyphenation patterns
% for a language with a different name. If the naming convention
% follows \xpackage{babel's} rules, then the hyphenation patterns
% for a language can be replaced by the alternative hyphenation patterns,
% provided in the format file.
% \end{abstract}
%
% \tableofcontents
%
% \section{Documentation}
%
% \subsection{In short}
%
% The package is an experimental package that allows the substitution
% of hyphenation patterns, example:
%\begin{quote}
%\begin{verbatim}
%\RequirePackage[ngerman=ngerman-x-20080601]{hyphsubst}
%\documentclass{article}
%\usepackage[ngerman]{babel}
%\end{verbatim}
%\end{quote}
% The patterns \texttt{ngerman} are replaced
% by the patterns \texttt{ngerman-x-20080601}. The format
% must contain these patterns and should use the naming scheme
% of either \xpackage{babel}'s \xfile{language.dat} or
% \xfile{etex.src}'s \xfile{language.def}.
%
% \subsection{Longer version}
%
% Assume the format may contain the following hyphenation patterns
% (excerpt from \xfile{language.dat}):
%\begin{quote}
%\begin{verbatim}
%...
%ngerman dehyphn.tex
%ngerman-x-20071231 dehyphn-x-20071231
%ngerman-x-20080601 dehyphn-x-20080601
%=ngerman-x-latest % alias for ngerman-x-20080601
%...
%\end{verbatim}
%\end{quote}
% The patterns that contain \texttt{-x-} are experimental new patterns
% for \texttt{ngerman}. However, package \xpackage{babel} does not provide
% the use of patterns that do not have the same name as the used language
% (dialect). The \xpackage{babel} system remembers patterns in
% macros: \verb|\l@|\meta{name}. \eTeX's \xfile{etex.src} uses
% \verb|\lang@|\meta{name} instead. In the following we use \xfile{babel}'s
% naming scheme, but \xfile{etex.src}'s naming scheme is supported, too.
%
% This package \xpackage{hyphsubst} solves the problem by redefining
% the macro \verb|\l@|\meta{name} to use other patterns.
%
% \begin{declcs}{HyphSubstLet} \M{nameA} \M{nameB}
% \end{declcs}
% \verb|\l@|\meta{nameA} now has the same meaning as
% \verb|\l@|\meta{nameB}.
% The patterns for \texttt{nameB} must exist. If the patterns for \texttt{nameA}
% exist, then they will be overwritten to use the patterns for \texttt{nameB}.
% Example:
%\begin{quote}
%\begin{verbatim}
%\documentclass{article}
%\usepackage{hyphsubst}
%\HyphSubstLet{ngerman}{ngerman-x-20080601}
%\usepackage[ngerman]{babel}
%\end{verbatim}
%\end{quote}
% Now the patterns \texttt{ngerman-x-20080601} are be used.
%
% Or if you want to compare hyphenations:
%\begin{quote}
%\begin{verbatim}
%\documentclass{article}
%\usepackage{hyphsubst}
%  % save original patterns for ngerman in ngerman-saved
%\HyphSubstLet{ngerman-saved}{ngerman}
%\usepackage[ngerman]{babel}
%\begin{document}
%  We start with the original patterns for ngerman.
%  \HyphSubstLet{ngerman}{ngerman-x-latest}%
%  Now we are using ngerman-x-latest.
%  \HyphSubstLet{ngerman}{ngerman-saved}%
%  Again we are using the original patterns.
%\end{document}
%\end{verbatim}
%\end{quote}
%
% \begin{declcs}{HyphSubstIfExists} \M{name} \M{then} \M{else}
% \end{declcs}
% Tests if patterns with name \meta{name} exist and execute
% \meta{then} in case of success and \meta{else} otherwise.
%
% \subsection{\LaTeX}
%
% The package can also be loaded before \cs{documentclass}:
%\begin{quote}
%\begin{verbatim}
%\RequirePackage[ngerman=ngerman-x-20080601]{hyphsubst}
%\documentclass{article}
%...
%\end{verbatim}
%\end{quote}
% This allows to put the package in a format file.
%
% Package options are interpreted as `let' assignments and passed
% to macro \cs{HyphSubstLet}:
%\begin{quote}
%\begin{verbatim}
%\usepackage[ngerman=ngerman-x-20080601]{hyphsubst}
%\end{verbatim}
%\end{quote}
% The part before the equal sign is the first argument for
% \cs{HyphSubstLet} and the part after the equal sign forms the
% second argument:
%\begin{quote}
%\begin{verbatim}
%\HyphSubstLet{ngerman}{ngerman-x-20080601}
%\end{verbatim}
%\end{quote}
% Note, this only works for direct package options. Global options
% are ignored.
%
% \subsection{\plainTeX}
%
% The package can be loaded and used with \plainTeX, e.g.:
%\begin{quote}
%\begin{verbatim}
%\input hyphsubst.sty
%\HyphSubstLet{ngerman}{ngerman-x-latest}
%\end{verbatim}
%\end{quote}

%% \section{Installation}
%
% \subsection{Download}
%
% \paragraph{Package.} This package is available on
% CTAN\footnote{\CTANpkg{hyphsubst}}:
% \begin{description}
% \item[\CTAN{macros/latex/contrib/oberdiek/hyphsubst.dtx}] The source file.
% \item[\CTAN{macros/latex/contrib/oberdiek/hyphsubst.pdf}] Documentation.
% \end{description}
%
%
% \paragraph{Bundle.} All the packages of the bundle `oberdiek'
% are also available in a TDS compliant ZIP archive. There
% the packages are already unpacked and the documentation files
% are generated. The files and directories obey the TDS standard.
% \begin{description}
% \item[\CTANinstall{install/macros/latex/contrib/oberdiek.tds.zip}]
% \end{description}
% \emph{TDS} refers to the standard ``A Directory Structure
% for \TeX\ Files'' (\CTANpkg{tds}). Directories
% with \xfile{texmf} in their name are usually organized this way.
%
% \subsection{Bundle installation}
%
% \paragraph{Unpacking.} Unpack the \xfile{oberdiek.tds.zip} in the
% TDS tree (also known as \xfile{texmf} tree) of your choice.
% Example (linux):
% \begin{quote}
%   |unzip oberdiek.tds.zip -d ~/texmf|
% \end{quote}
%
% \subsection{Package installation}
%
% \paragraph{Unpacking.} The \xfile{.dtx} file is a self-extracting
% \docstrip\ archive. The files are extracted by running the
% \xfile{.dtx} through \plainTeX:
% \begin{quote}
%   \verb|tex hyphsubst.dtx|
% \end{quote}
%
% \paragraph{TDS.} Now the different files must be moved into
% the different directories in your installation TDS tree
% (also known as \xfile{texmf} tree):

% If you have a \xfile{docstrip.cfg} that configures and enables \docstrip's
% TDS installing feature, then some files can already be in the right
% place, see the documentation of \docstrip.
%
% \subsection{Refresh file name databases}
%
% If your \TeX~distribution
% (\TeX\,Live, \mikTeX, \dots) relies on file name databases, you must refresh
% these. For example, \TeX\,Live\ users run \verb|texhash| or
% \verb|mktexlsr|.
%
% \subsection{Some details for the interested}
%
% \paragraph{Unpacking with \LaTeX.}
% The \xfile{.dtx} chooses its action depending on the format:
% \begin{description}
% \item[\plainTeX:] Run \docstrip\ and extract the files.
% \item[\LaTeX:] Generate the documentation.
% \end{description}
% If you insist on using \LaTeX\ for \docstrip\ (really,
% \docstrip\ does not need \LaTeX), then inform the autodetect routine
% about your intention:
% \begin{quote}
%   \verb|latex \let\install=y\input{hyphsubst.dtx}|
% \end{quote}
% Do not forget to quote the argument according to the demands
% of your shell.
%
% \paragraph{Generating the documentation.}
% You can use both the \xfile{.dtx} or the \xfile{.drv} to generate
% the documentation. The process can be configured by the
% configuration file \xfile{ltxdoc.cfg}. For instance, put this
% line into this file, if you want to have A4 as paper format:
% \begin{quote}
%   \verb|\PassOptionsToClass{a4paper}{article}|
% \end{quote}
% An example follows how to generate the
% documentation with pdf\LaTeX:
% \begin{quote}
%\begin{verbatim}
%pdflatex hyphsubst.dtx
%makeindex -s gind.ist hyphsubst.idx
%pdflatex hyphsubst.dtx
%makeindex -s gind.ist hyphsubst.idx
%pdflatex hyphsubst.dtx
%\end{verbatim}
