% \begin{abstract}
%  \GlossTeX{} is a tool for the preparation of glossaries, lists of
%  acronyms or sorted lists in general. It greatly
%  simplifies this task. One or more glossary-definition files serve as
%  databases which contain descriptions of terms. These terms are
%  identified through labels. Based upon labels set into the
%  \TeX{}-source, \GlossTeX{} determines which entries have to appear in
%  the typeset list. \GlossTeX{} uses \MakeIndex{} for the sorting of the
%  lists. References to the place where a term appears in the text
%  can be set in the list. A term consists of a label which is
%  used to identify it, an optional item describing the typeset
%  output, an optional long-form and the actual text representing
%  it. There are many ways to access each of these fields within
%  the document. It is also possible to generate cross-references 
%  to another term. \GlossTeX{} is well customizable in respect to
%  the produced output.

% \section{Introduction}
% \subsection{Purpose}
% \GlossTeX{} is a tool for the automatic preparation of glossaries,
% lists of acronyms, nomenclature and sorted lists in general. Based
% upon the labels set into the \TeX{}-source, \GlossTeX{} determines
% which entries from a glossary-definition file have to be processed
% to generate the list. \GlossTeX{} then creates an intermediate file
% that has to be processed by \MakeIndex{} for sorting. The output of
% \MakeIndex{} is then included into the \TeX{}-source for
% typesetting. With each term associated is an item representing the
% typeset output, an optional long-form if it's an acronym and an
% optional descriptive text. These elements can all be accessed within
% the document in many ways.
%
% \subsection{History}
% I created \GlossTeX{} because there were no tools for the
% preparation of glossaries that fit my needs. \GlossTeX{} is mainly a
% combination of the features of the packages \package{acronym},
% \package{nomencl} and \GloTeX{}. The commands starting with |\ac|
% are taken more or less directly from \package{acronym} and the way
% \GlossTeX{} handles page references is almost identical to the way
% \package{nomencl} does. The use of glossary databases is inspired by
% \GloTeX{}.
%
% \subsection{Legalise}
% \GlossTeX{} is provided ``as is'' and comes with absolutely no
% warranty. It is covered by the GNU General Public License (see the
% file |COPYING| that comes with this package).

%
% \section{Building and Installation}
% First, you need to build glosstex from its C sources. Note that you
% need an ANSI C compiler. If you have
% MAKE and a decent OS (speak \unix{}), typing |make| from the shell
% should build the binary (have a 
% look at the various makefiles, namely |Makefile| (which is my rather
% complex development version that may not run on your system setup),
% |Makefile.unx| (which is the most generic one) and
% |Makefile.os2|). Also have a look at the start of the makefiles
% where you will find some variables to be customized. The most
% important ones may be |CC| and |SHELL|. You may also want to have a
% look at |config.h|.
%
% If you don't
% have MAKE get it right now or just issue 
% these commands: 
%
% \begin{example}
%   |cc -c database.c -o database.o|\\
%   |cc -c error.c -o error.o|\\
%   |cc -c labels.c -o labels.o|\\
%   |cc -c list.c -o list.o|\\
%   |cc -c main.c -o main.o|\\
%   |cc -c version.c -o version.o|\\
%   |cc database.o error.o labels.o list.o main.o version.o -o glosstex|
% \end{example}
%
% Now just move the resulting binary to a directory where your other
% binaries live. After that you need to unpack |glosstex.dtx|. Do this
% by invoking
% \begin{example}
%   |latex glosstex.ins|
% \end{example}
%
% which will produce some more files. You will have to move them
% to their proper places according to your particular
% \TeX{}-installation. The instructions that will appear on the
% screen should give you a good start.
%
% \subsection{A Goodie for \teTeX{} User}
% If you are using \textsc{Thomas Esser}'s fantastic \teTeX{} system,
% \GlossTeX\ has some good news for you. \GlossTeX\ comes with a
% kpathsea shell-wrapper which supports path searching. For this to
% work, rename |glosstex| to |glosstex.bin| and |glosstex.sh| to
% |glosstex|. Put them somewhere convenient. Now add a line of the
% form
% \begin{example}
% |GDFINPUTS = $KPSE_DOT:$TEXMFS/glosstex//|
% \end{example}
% in you |texmf.cnf| file. That's it!
%
% If you get problems, the following notes may help you. 
% First check whether
% \begin{example}
%  |kpsetool -v -n glosstex '$GDFINPUTS'|
% \end{example}
% and 
% \begin{example}
%  |kpsetool -v -n tex '$GDFINPUTS'| 
% \end{example}
%
% do what you want, i.e.\ their output
% should be equal. These won't find your \teTeX{} |texmf| tree (where
% your |texmf.cnf| file lives) if |glosstex| is not in something like
% |teTeX/bin| or |teTeX/bin/i386-linux|. In these cases, replace
% \begin{example}
% |TETEXDIR = $SELFAUTOPARENT| 
% \end{example}
% in |texmf.cnf| with something like
% \begin{example}
% |TETEXDIR = /usr/local/lib/teTeX|.
% \end{example}
%  This makes sure that the proper |texmf| tree is found, even if
%  |glosstex| is not in the \teTeX{} 
% |texmf| tree but in your local |texmf| tree.
% 
% You also need symbolic links from e.\,g.\ 
% |/usr/local/lib/localTeX/texmf.cnf| to your \teTeX{} |texmf.cnf|. This
% is because kpathsea looks for |texmf.cnf| in the tree where the
% binary was found.
%
% These instructions should apply to \teTeX{} version 0.4 or newer.
%
% \section{Usage}
% The \LaTeX{}-macros needed by \GlossTeX{} have to be included into
% the source using
%
% \begin{example}
%   |\usepackage|\opt{|[|\meta{options}|]|}|{glosstex}|
% \end{example}
%
% Valid \meta{options} are listed in table \ref{tab:options}.
%
% \begin{table}[htbp]
% \begin{center}
% \begin{tabular}{>{\ttfamily}ll}
% \hline\hline
% \rmfamily Option & Discussed in section\\
% \hline
% refpage, \textit{norefpage} &\ref{sec:page_references}\\
% \textit{itemfirst}, longfirst &\ref{sec:order}\\
% \textit{text}, footnote &\ref{sec:footnotes}\\
% \textit{roundparen}, squareparen&\ref{sec:parentheses}\\
% \hline\hline
% \end{tabular}
% \caption[Package options.]{Package options. Defaults are set in
% \textit{italics}.}
% \label{tab:options}
% \end{center}
% \end{table}
%
% Whenever you want a term to appear in the glossary, you insert
% \DescribeMacro{\glosstex}
% \begin{definition}
%   |\glosstex|\opt{|(|\meta{list}|)|}\opt{|[|\meta{pageref-mode}|]|}|{|\meta{label}|}|
% \end{definition}
%
% into the text. \meta{label} references the entry and the optional
% arguments \meta{pageref-mode} and \meta{list} determine the mode for
% page references\footnote{Page references are described in section
% \ref{sec:page_references}. \meta{pageref-mode} works in conjunction
% with the optional arguments |refpage| and |norefpage| to the package
% and defaults to |p|. \meta{list} defaults to |glo|.} and the list
% the referenced term should appear in.
%
% But you can create $n$ independent lists and make each \meta{label}
% appear in any \meta{list}, each appearance independent of the other
% ones. To facilitate the creation of multiple \meta{list}s and
% especially make it easy to achieve the most likely usage, there are
% actually two sets of commands. One set starting with |\gl| defaults
% to \meta{list} |glo| (which stands for glossary) and
% \meta{pageref-mode} |p|, the other set starting with |\ac| defaults
% to \meta{list} |acr| (list of acronyms) and \meta{pageref-mode}
% |n|. The following is the equivalent to |\glosstex| for acronyms:
%
% \DescribeMacro{\acronym}
% \begin{definition}
%   |\acronym|\opt{|(|\meta{list}|)|}\opt{|[|\meta{pageref-mode}|]|}|{|\meta{label}|}| 
% \end{definition}
%
% These two commands can also be called as |\glosstex{*}| and
% |\acronym{*}| to include all terms found in the |.gdf|-files into
% the corresponding \meta{list}. This is similar to the command
% |\nocite{*}| in \BibTeX{} and is primarily meant for debugging
% purposes. But do \emph{not} use something like |\gls{*}| (see
% below).
%
% There is another set of commands that produce both an entry in the
% list (this is optional) and typeset output. 
%
% \DescribeMacro{\gls}
% \DescribeMacro{\gls*}
% \begin{definition}
%   |\gls|\opt{|*|}\opt{|(|\meta{list}|)|}\opt{|[|\meta{pageref-mode}|]|}|{|\meta{label}|}|
% \end{definition}
%
% |\gls| typesets \meta{item} and produces a list entry (\meta{list}
% defaults to |glo|).  The starred version |\gls*| just produces
% typeset output without a list-entry.\footnote{To be honest, a
% list-entry is produced, but it never appears in the output. The
% starred version implicitly produces entries with \meta{list-mode}
% |n| (never appear in typeset \meta{list}) while the unstarred
% versions set \meta{list-mode} to |a| (always appear). There is no
% other way of specifying the \meta{list-mode} of an \meta{label}.}
%
% \DescribeMacro{\ac}
% \DescribeMacro{\ac*}
% \DescribeMacro{\acs}
% \DescribeMacro{\acs*}
% \DescribeMacro{\acl}
% \DescribeMacro{\acl*}
% \DescribeMacro{\acf}
% \DescribeMacro{\acf*}
% \begin{definition}
%   |\ac|\opt{|*|}\opt{|,|\meta{lparen}|,|\meta{rparen}|,|}\opt{|<|\meta{form}|>|}\opt{|(|\meta{list}|)|}\opt{|[|\meta{pageref-mode}|]|}|{|\meta{label}|}|\\
%   |\acs|\opt{|*|}\opt{|(|\meta{list}|)|}\opt{|[|\meta{pageref-mode}|]|}|{|\meta{label}|}|\\
%   |\acl|\opt{|*|}\opt{|(|\meta{list}|)|}\opt{|[|\meta{pageref-mode}|]|}|{|\meta{label}|}|\\
%   |\acf|\opt{|*|}\opt{|,|\meta{lparen}|,|\meta{rparen}|,|}\opt{|<|\meta{form}|>|}\opt{|(|\meta{list}|)|}\opt{|[|\meta{pageref-mode}|]|}|{|\meta{label}|}|
% \end{definition}
%
% These all produce typeset output. |\acs| typesets \meta{item},
% |\acl| typesets \meta{long-form} and |\acf| typesets \meta{full}
% (see section \ref{sec:format}). |\ac| works like |\acf| at it's first
% invocation and like |\acs| on all subsequent ones. Using |\ac| you
% can make sure that an acronym is always spelled out at least once in
% your document while safely using the short form whenever
% possible. Note that the use of |\acf| has no effect on subsequent
% invocations of |\ac|. The starred versions |\ac*|, |\acs*|, |\acl*|
% and |\acf*| 
% just produce typeset output. Table~\ref{tab:commands} gives an
% overview of all this.
%
% \begin{table}[htbp]
%  \begin{center}
%    \begin{tabular}{rllll}
%      \hline\hline
%      defaults & list & list and text & text & output\\
%      \hline
%      |(glo)[p]| & |\glosstex| & |\gls| & |\gls*| & \meta{item}\\
%      |(acr)[n]| & |\acronym| & |\ac| & |\ac*| 
% & \meta{item} or \meta{full}\\
%      |(acr)[n]| & & |\acs| & |\acs*| & \meta{item}\\
%      |(acr)[n]| & & |\acl| & |\acl*| & \meta{long-form}\\
%      |(acr)[n]| & & |\acf| & |\acf*| & \meta{full}\\
%      \hline\hline
%    \end{tabular}
%    \caption{Overview of the different sets of commands.}
%    \label{tab:commands}
%  \end{center}
% \end{table}
%
% In the most simple case, \meta{full} will look like ``\meta{item}
% |(|\meta{long-form}|)|''. You can switch the order of \meta{item}
% and \meta{long-form} by using the options |itemfirst| and
% |longfirst|. If you rather like either in a footnote, try the option
% |footnote| instead of the default |text|. If you don't like the
% round parentheses, just use the optional arguments \meta{lparen},
% \meta{rparen} which are also described in section \ref{sec:format}.
%
% \subsection{The Glossary Definition File}
% A glossary-definition file\glosstex{gdf-file} (suffix |.gdf|) is
% needed which serves as a database for \GlossTeX{}, holding the
% actual descriptions of all terms. You can have $m$ |.gdf|-files that
% contain the definitions to the \meta{label}s you reference in your
% documents. Entries have the form
% \begin{definition}
%   |@entry{|\meta{label}\opt{|,|\meta{item}\opt{|,|\meta{long-form}}}|}| \opt{\meta{text}}
% \end{definition}
%
% where \meta{label} is used to identify the entry and \meta{text} may
% contain any amount of \TeX{}-source, being the actual definition of
% the item. You should know that \meta{label} is used to construct
% \TeX{}-macros, so it shouldn't contain funny characters or you will
% most likely get funny errors.  The optional argument \meta{item}
% describes the appearance of the item in the produced list. If
% omitted, it defaults to \meta{label}. It can be used when some
% special form of typesetting is wanted. \meta{item} can contain any
% \TeX{}-construct, as long as each ``|{|'' has a corresponding
% ``|}|'' or \GlossTeX{} will get confused. The same applies
% to \meta{long-form}, except that it defaults into an empty string if
% not specified.
%
% Following is the |.gdf|-file used for this documentation. Note the use of
% ``|~|'' as the quote-character. Also note that all lines
% until the first line starting with |@entry{| are
% ignored. Additionally, all lines starting with ``|%|'' are ignored,
% too. Thus they
% can serve as comments.
%    \begin{macrocode}

%</gdf>
%    \end{macrocode}
%
% \subsection{Invocation}
% After the first run of \LaTeX{}, the |.aux|-file contains all
% necessary information for the preparation of the glossary. \GlossTeX\
% is then invoked to read one or more |.gdf|-files and outputs all
% definitions that are referenced in the |.aux|-file. The output of
% \GlossTeX{} is then processed by \MakeIndex{} for sorting.
%
% \GlossTeX{} is invoked in a \unix{}-like environment using the
% following command
%
%\begin{example}
%  |glosstex |\meta{aux-file}| |\meta{gdf-file}| |\opt{\meta{gdf-file}\opt{...}}| |\opt{|-v|\opt{|0|\ldots|5|}} 
% \end{example}
%
% This produces 2 files as output, one \gls{gxs-file} to be input into
% \MakeIndex{} and a log-file with extension |.gxg|\glosstex{gxg-file}
% which contains more detailed information. The |-v| option selects
% how verbose \GlossTeX{} should be when writing the log-file. |-v| is
% equal to |-v4| and |-v2| is the default. |-v0| makes \GlossTeX{}
% shut his mouth and only report errors and |-v5| makes \GlossTeX{}
% really talkative.
%
% \MakeIndex{}  has to be invoked in this way
%
% \begin{example}
%   |makeindex |\meta{gxs-file}| -o |\meta{glx-file}| -s |glosstex.ist| |\opt{|-t |\meta{glg-file}}
% \end{example}
%
% The commands
%
% \begin{example}
% |glosstex thesis thesis.gdf master.gdf|\\
% |makeindex thesis.gxs -o thesis.glx -s glosstex.ist|
% \end{example}
%
% produce the final \gls{glx-file} which is then included by
% \DescribeMacro{\printglosstex}
% \begin{definition}
%  |\printglosstex|\opt{|(|\meta{list}|)|}\opt{|[|\meta{pageref-mode}|]|}
% \end{definition}
% during the next \LaTeX{}-run. The argument \meta{pageref-mode}
% supersedes the one given to the entries individually for each
% \meta{list} and defaults to |p|. You can turn on page references
% unconditionally for each \meta{list} individually by using
% \meta{pageref-mode} |a| and turn it off by using
% \meta{pageref-mode} |n| as argument to |\printglosstex|. See also
% table~\ref{tab:references} for an overview of these options.
% 
% Note that, no matter of how many \meta{list}s you produce, there is
% always exactly \emph{one} |.glx|-file which contains the entries of
% \emph{all} produced lists. 
%
% Depending on whether you use \meta{item}
% or \meta{long-form} in your text or you have cross-references, it
% may be necessary to run \LaTeX{} and \GlossTeX{} up to 4 times until
% all references are resolved. Watch out for warnings from
% \package{glosstex} during a \LaTeX{} run. Messages about unresolved
% \meta{label}s from \GlossTeX{} are caused by missing definitions in
% the |.gdf|-files.
%
% \subsection{Page References}
% \label{sec:page_references}
% You may want a reference in the list to the place where the term
% first appears in the text. This can be done using the optional
% argument \meta{pageref-mode} on \meta{item}-level and
% \meta{list}-level. These arguments in combination with the option to
% |\usepackage| control page references. Table \ref{tab:references}
% gives an overview of all possible combinations of these 3
% arguments.
%
% \begin{table}[htbp]

%  \begin{tabular}{l|ccc|ccc}
%    \hline\hline
%    \hfill list & & |refpage| & & & |norefpage|\\

%    \hline
%    |a| & $\times$ & $\times$ & $-$ & $\times$ & $\times$ & $-$\\
%    |p| & $\times$ & $\times$ & $-$ & $\times$ & $-$ & $-$\\
%    |n| & $\times$ & $-$ & $-$ & $\times$ & $-$ & $-$\\
%    \hline\hline
%  \end{tabular}
%  \caption[Options controlling the appearance of page
%    references.]{Options controlling the appearance of page
%    references. A ``$\times$'' indicates that a reference is
%    produced.}
%  \label{tab:references}
% \end{center}
% \end{table}
%
% One possible usage of this feature: while debugging a document, turn
% on page references by using the option |refpage| to the
% package. Every entry included with the modes |a| (always) or the
% default |p| (package) will contain a reference. After debugging,
% remove the option |refpage| and only those entries that were
% included with mode |a| will still have a reference.
%
% \subsection{The Appearance of \protect\meta{full}}
% \label{sec:format}
% \meta{full} stands for the appearance of the typeset term in the
% text. The appearance of \meta{full} is controlled through the
% optional arguments \meta{lparen}, \meta{rparen} and \meta{form} to
% |\ac| and |\acf|. Additionally, these arguments work together with
% defaults set forth on \meta{list}-level and package level. The
% following sections shall shed some light on this topic.
%
% \subsubsection{The \protect\meta{order} of \protect\meta{item}s}
% \label{sec:order} 
% \DescribeMacro{\glxitemorderdefault}
% The options |itemfirst| and |longfirst| control which one of
% \meta{item} and \meta{long-form} should be typeset first. On
% \meta{list}-level, \meta{item-order} can be set using
% \begin{definition}
% |\glxitemorderdefault||{|\meta{list}|}||{|\meta{item-order}|}|
% \end{definition}
% \meta{item-order} may be either ``|i|'',
% ``|l|'' or empty. |i| first typesets \meta{item}, |l| first typesets
% \meta{long-form}. Omitting \meta{item-order} lets the defaults take
% effect. Table \ref{tab:item-order} gives an overview over each
% combination of the options for \meta{item-order}.
%
% \begin{table}[htbp]
% \begin{center}
%  \begin{tabular}{l|ccc|ccc}
%    \hline\hline
%    \hfill list & & |itemfirst| & & & |longfirst|\\

%    \hline
%    |i| & |i| & |i| & |l| & |i| & |i| & |l|\\
%    $-$ & |i| & |i| & |l| & |i| & |l| & |l|\\
%    |l| & |i| & |l| & |l| & |i| & |l| & |l|\\
%    \hline\hline

% The aforementioned \meta{form} is built by simply concatenating

% \meta{form} argument to |\ac| and |\acf| by enclosing it in angle
% brackets, just like |\ac<if>{foo}| or |\ac<t>{bar}|. Please note that

% \end{definition}

% \begin{definition}
% |\glxparenlistdefault{|\meta{list}|}{|\meta{lparen}|}{|\meta{rparen}|}|
% \end{definition}
% sets this option on \meta{list}-level. On \meta{item}-level these

% |\acf,--,--,<lt>{bar}|. It may look strange, but I was out of
% parentheses.
%
% \subsection{Cross-References}
% \DescribeMacro{\glxref}
% \DescribeMacro{\glxref*}
% \begin{definition}
% |\glxref|\opt{|*|}|{|\meta{item}|}|
% \end{definition}
% It may be useful to use cross-references in entries. Assume
% you have referenced |\glosstex{ascii}| which describes the term
% \ac{ASCII}. You may also want to include \ac*{EBCDIC} as an
% example for another character encoding. To achieve this, write this
% into the definition of \ac{ASCII}
%
% \begin{example}
% |See also \glxref{ebcdic}.|
% \end{example}
%
% and \GlossTeX{} then produces ``See also EBCDIC'' and also includes
% the definition for \ac*{EBCDIC} into the same list \ac{ASCII}
% appears in. Note 
% that |\glxref| is only available within the \meta{text} argument in
% the |.gdf|-file since it only makes sense within a
% \meta{list}. There is also a starred version |\glxref*| that doesn't
% produce typeset output.
%
% \subsection{\GlossTeX{} and \package{nomencl}}
% It is possible to use \package{nomencl} and \GlossTeX{} in one
% document without problems. The following commands show how to deal with documents using both
% \GlossTeX{} and \textsf{nomencl}.
% \begin{example}
% |latex thesis|\\
% |glosstex thesis thesis.gdf |\\
% |makeindex thesis.gxs -o thesis.glx -s glosstex.ist|\\
% |makeindex thesis.glo -o thesis.gls -s nomencl.ist|\\
% |latex thesis|
% \end{example}
%
% \section{Customizing}
% \subsection{Global}
% \GlossTeX{} can be customized by using the file |glosstex.cfg| which
% is automatically loaded if it is present. The file |glosstex.std| is
% the default configuration file that is absolutely mandatory to
% \GlossTeX{}'s proper working. It
% shows all aspects that are meant to be customized, so let's discuss
% it now.
%
% Each term that gets typeset either goes through |\GLX@output@short|
% or |\GLX@output@long|, depending whether it's the \meta{item} or
% \meta{long-form}. These macros each take 3 arguments and get called
% this way:
% \begin{definition}
%   |\GLX@output@short{|\meta{label}|}{|\meta{list}|}{|\meta{item}|}|\\
%   |\GLX@output@long{|\meta{label}|}{|\meta{list}|}{|\meta{long-form}|}|
% \end{definition}
%
% \begin{macro}{\GLX@output@short}
% \begin{macro}{\GLX@output@long}
% We just output \meta{item} as it is. See section
% \ref{sec:customizing_local} for some more elaborate implementation
% of this macro.

% \DescribeMacro{\glxgldefault}

% \meta{paren} on package level, you may as well use the options
% |roundparen| and |squareparen|. Because |roundparen| is the default
% option, this command is not used. As long as there is no
% \meta{paren}-default on \meta{list}-level, the default on
% package-level is used. So therefor, |\glxparenlistdefault| is not
% used here as well.

% \subsection{Local}
% \label{sec:customizing_local}
% Now we need a local configuration file for this document. This is
% done by using a file named |glosstex.cfg|. 
% In |\GLX@output@short| we test whether we are in the list of acronyms
% (|GLX@acdef@list|) and typeset \meta{item} with caps and small caps
% if we are. Otherwise, just typeset \meta{item}.
% We also define a call
%  to |\index| in |\GLX@output@short|. As sort-key, we use
% \meta{label}. Instead of the usual |@| we use |=| for designating
% the appearance part of the index entry.
%    \begin{macrocode}
%<*cfg>
\renewcommand{\GLX@output@short}[3]{%
  \ifthenelse{\equal{#2}{\GLX@acdef@list}}{%
    \textsc{#3}}{#3}\index{#1=#3}}
%</cfg>
%    \end{macrocode}
%
% \section{Some Details}
% While reading the |.aux|-file, \GlossTeX{} only considers the first
% appearance of one \meta{item} for each \meta{list}. All subsequent
%  entries are silently ignored. 
% (Almost silently, because the |.gxg|-file will contain detailed
% information about this, and more.) But if the first entry says 
% not to produce a page reference and a following one says to do so, then
% the latter will supersede the former. The same applies if a
% term is referenced without the option not to generate a list-entry
% (all commands containing a |*|, e.g.\ |\gl*|), but a following tells
% to do so.
%
% While reading one or more |.gdf|-files, only the first definition is
% used, all other entries are ignored. This fact can be utilised
% in some way. Assume you have a |master.gdf| which contains general
% terms and a file |thesis.gdf| which only contains terms that are
% intended for use in your thesis. Whenever an entry is present in both
% |.gdf|-files, the one from |thesis.gdf| should be taken. To achieve
% this, specify |thesis.gdf| \emph{before} |master.gdf|.
%
% Additionally, see the file |TODO| in this package for
% known bugs (also called features) and not yet implemented features
% (also called bugs).

% it is tightly coupled to the features of \MakeIndex{}. Note the use
% of ``|~|'' as |quote| to enable german word-ordering using the |-g|
% option to \MakeIndex{}. So if you want a ``|~|'' in your |.gdf|-file,
% you have to type ``|~~|''
