% \section{Documentation}
%
% \subsection{Introduction}
%
% \LaTeX\ supports the direct use of 8-bit characters by means
% of package \xpackage{inputenc}. However you must know
% and specify the encoding, e.g.:
% \begin{quote}
%   \ttfamily
%   |\documentclass{article}|\\
%   |\usepackage[|\EM{latin1}|]{inputenc}|\\
%   |% or \usepackage[|\EM{utf8}|]{inputenc}|\\
%   |% or \usepackage[|\EM{??}|]{inputenc}|\\
%   |\begin{document}|\\
%   |  |\ExampleText\\
%   |\end{document}|
% \end{quote}
%
% If the document is transferred in an environment that
% uses a different encoding, then there are programs that
% convert the input characters. Examples for conversion
% of file \xfile{test.tex}
% from encoding latin1 (ISO-8859-1) to UTF-8:
% \begin{quote}
%   \ttfamily
%   |recode ISO-8859-1..UTF-8 test.tex|\\
%   |recode latin1..utf8 test.tex|\\
%   |iconv --from-code ISO-8859-1|\\
%   \hphantom{iconv}| --to-code UTF-8|\\
%   \hphantom{iconv}| --output testnew.tex|\\
%   \hphantom{iconv}| test.tex|\\
%   |iconv -f latin1 -t utf8 -o testnew.tex test.tex|
% \end{quote}
% However, the encoding name for package \xpackage{inputenc}
% must be changed:
% \begin{quote}
%    |\usepackage[latin1]{inputenc}| $\rightarrow$
%    |\usepackage[utf8]{inputenc}|\kern-4pt\relax
% \end{quote}
% Of course, unless you are using some clever editor
% that knows package \xpackage{inputenc}, recodes
% the file and adjusts the option at the same time.
% But most editors can perhaps recode the file, but
% they let the option untouched.
%
% Therefore package \xpackage{selinput} chooses another way for
% specifying the input encoding. The encoding name is not needed
% at all. Some 8-bit characters are identified by their glyph
% name and the package chooses an appropriate encoding, example:
% \begin{quote}
%   \ttfamily
%   |\documentclass{article}|\\
%   |\usepackage{selinput}|\\
%   |\SelectInputMappings{|\\
%   |  adieresis={|\EM{\"a}|}|,\\
%   |  germandbls={|\EM{\ss}|}|,\\
%   |  Euro={|\EM{\texteuro}|}|,\\
%   |}|\\
%   |\begin{document}|\\
%   |  |\ExampleText\\
%   |\end{document}|
% \end{quote}
%
% \subsection{User interface}
%
% \begin{declcs}{SelectInputEncodingList} \M{encoding list}
% \end{declcs}
% \cs{SelectInputEncodingList} expects a comma separated list of
% encoding names. Example:
% \begin{quote}
%   |\SelectInputEncodingList{utf8,ansinew,mac-roman}|
% \end{quote}
% The encodings of package \xpackage{inputenx} are used as default.
%
% \begin{declcs}{SelectInputMappings} \M{mapping pairs}
% \end{declcs}
% A mapping pair consists of a glyph name and its input
% character:
% \begin{quote}
%   |\SelectInputMappings{|\\
%   |  adieresis={|\EM{\"a}|}|,\\
%   |  germandbls={|\EM{\ss}|}|,\\
%   |  Euro={|\EM{\texteuro}|}|,\\
%   |}|
% \end{quote}
% The supported glyph names can be found in file \xfile{ix-name.def}
% of project \xpackage{inputenx} \cite{inputenx}. The names are
% basically taken from Adobe's glyphlists \cite{adobe:glyphlist,adobe:aglfn}.
% As many pairs are needed as necessary to identify the encoding.
% Example with insufficient pairs:
% \begin{quote}
%   \ttfamily
%   |\SelectInputEncodingSet{latin1,latin9}|\\
%   |\SelectInputMappings{|\\
%   |  adieresis={|\EM{\"a}|}|,\\
%   |  germandbls={|\EM{\ss}|}|,\\
%   |}|\\
%   \ExampleText| and Euro: |\EM{\textcurrency} (wrong)
% \end{quote}
% The first encoding \xoption{latin1} passes the constraints given
% by the mapping pairs. However the Euro symbol is not part of
% the encoding. Thus a mapping pair with the Euro symbol
% solves the problem. In fact the symbol alone already succeeds in selecting
% between \xoption{latin1} and \xoption{latin9}:
% \begin{quote}
%   \ttfamily
%   |\SelectInputEncodingSet{latin1,latin9}|\\
%   |\SelectInputMappings{|\\
%   |  Euro={|\EM{\texteuro}|},|\\
%   |}|\\
%   \ExampleText| and Euro: |\EM{\texteuro}
% \end{quote}
%
% \subsection{Options}
%
% \begin{description}
% \item[\xoption{warning}:]
%   The selected encoding is written
%   by \cs{PackageInfo} into the \xfile{.log} file only.
%   Option \xoption{warning} changes it to \cs{PackageWarning}.
%   Then the selected encoding is shown on the terminal as well.
% \item[\xoption{ucs}:]
%   The encoding file \xfile{utf8x} of package \cs{ucs} requires
%   that the package itself is loaded before.
%   If the package is not loaded, then the option \xoption{ucs}
%   will load package \xpackage{ucs} if the detected encoding is
%   UTF-8 (limited to the preamble, packages cannot be loaded later).
% \item[\xoption{utf8=\dots}:]
%   The option allows to specify other encoding files
%   for UTF-8 than \LaTeX's \xfile{utf8.def}. For example,
%   |utf8=utf-8| will load \xfile{utf-8.def} instead.
% \end{description}
%
% \subsection{Encodings}
%
% Package \xpackage{stringenc} \cite{stringenc}
% is used for testing the encoding. Thus the encoding
% name must be known by this package. Then the found
% encoding is loaded by \cs{inputencoding} by package
% \xpackage{inputenc} or \cs{InputEncoding} if package
% \xpackage{inputenx} is loaded.
%
% The supported encodings are present in the encoding list,
% thus usually the encoding names do not matter.
% If the list is set by \cs{SelectInputEncodingList},
% then you can use the names that work for package
% \xpackage{inputenc} and are known by package \xpackage{stringenc},
% for example: \xoption{latin1}, \xoption{x-iso-8859-1}. Encoding
% file names of package \xpackage{inputenx} are prefixed with \xfile{x-}.
% The prefix can be dropped, if package \xpackage{inputenx} is loaded.

% \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 selinput.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{selinput.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 selinput.dtx
%makeindex -s gind.ist selinput.idx
%pdflatex selinput.dtx
%makeindex -s gind.ist selinput.idx
%pdflatex selinput.dtx
%\end{verbatim}
