+%
+% \begin{declcs}{UniqueCounterNew} \M{name}
+% \end{declcs}
+% Macro \cs{UniqueCounterNew} creates a new unique counter \meta{name}.
+% An error is thrown, if the counter already exists.
+%
+% \begin{declcs}{UniqueCounterCall} \M{name} \M{code}
+% \end{declcs}
+% Macro \cs{UniqueCounterCall} calls the given \meta{code} with a new
+% value of counter \meta{name} as argument.
+%
+% \begin{declcs}{UniqueCounterIncrement} \M{name}
+% \end{declcs}
+% Macro \cs{UniqueCounterIncrement} generates a new value for the counter
+% \meta{name}
+% by incrementing by one (globally).
+%
+% \begin{declcs}{UniqueCounterGet} \M{name}
+% \end{declcs}
+% Expandable macro \cs{UniqueCounterGet} returns the current value
+% of counter \meta{name}

+%% \section{Installation}
+%
+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\CTANpkg{uniquecounter}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/uniquecounter/uniquecounter.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/uniquecounter/uniquecounter.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/uniquecounter.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 uniquecounter.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):
+% \begin{quote}
+% \def\t{^^A
+% \begin{tabular}{@{}>{\ttfamily}l@{ $\rightarrow$ }>{\ttfamily}l@{}}

+% 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{uniquecounter.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}
