+%
+% Unpacking:

+% (c) If you insist on using LaTeX

+% (a) If catchfile.drv is present:
+% latex catchfile.drv
+% (b) Without catchfile.drv:
+% latex catchfile.dtx; ...
+% The class ltxdoc loads the configuration file ltxdoc.cfg

+% \cs{CatchFileEdef} \M{cmd} \M{file name} \M{setup}

+% Macro \meta{cmd} is defined with the contents
+% of file \meta{file name}.
+% \cs{CatchFileDef} uses \cs{def}, \cs{CatchFileEdef} \cs{edef}
+% for the definition.
+% Additional setup code for setting
+% catcodes or treatment of line ends can be given in code

+%
+% \begin{macro}{\CatchFile@Input}
+% The package needs the expandable primitive \cs{input}.
+% However there are formats that redefine it. For example,

+% the primitive in \cs{@@input}. The third possibility
+% is \cs{pdfprimitive}, introduced in \pdfTeX\ 1.40.0.
+%
+% Thus we try to find the primitive and store it in
+% \cs{CatchFile@Input}. If it is used, it must be expanded
+% twice (because of the solution with \cs{pdfprimitive}).

+%
+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\CTANpkg{catchfile}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/catchfile/catchfile.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/catchfile/catchfile.pdf}] Documentation.
+% \end{description}
+%
+%
+% \paragraph{Bundle.} All the packages of the bundle `catchfile'
+% 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/catchfile.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{catchfile.tds.zip} in the
+% TDS tree (also known as \xfile{texmf} tree) of your choice.
+% Example (linux):
+% \begin{quote}
+% |unzip catchfile.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 catchfile.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@{}}
+% catchfile.sty & tex/generic/catchfile/catchfile.sty\\

+% 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|.

+% 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{catchfile.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 catchfile.dtx
+%makeindex -s gind.ist catchfile.idx
+%pdflatex catchfile.dtx
+%makeindex -s gind.ist catchfile.idx
+%pdflatex catchfile.dtx
+%\end{verbatim}
+% \end{quote}
