-% \begin{abstract}
-% Since version 1.40 \pdfTeX\ supports several color stacks. This
-% package uses a separate color stack for footnotes that can break
-% across pages.
-% \end{abstract}
-%
-% \tableofcontents
-%
-% \section{User interface}
-%
-% Just load the package:
-% \begin{quote}
-% |\usepackage{pdfcolfoot}|
-% \end{quote}
-% The package assigns a color stack for footnotes and patches
-% the appropriate internal macros to support this color stack.
-%
-% \subsection{Other packages or classes}
-%
-% This package \xpackage{pdfcolfoot} redefines \cs{@makecol}
-% and \cs{@makefntext}.
-% This can cause conflicts if other packages or classes also change
-% these macro in an incompatible way. Sometimes it can help
-% to change the package order.
-%
-% \section{Interface for package or class writers}
-%
-% Two macros \cs{pdfcolfoot@switch} and \cs{pdfcolfoot@current}
-% need to be added to get support of the color stack for footnotes.
-% This package \xpackage{pdfcolfoot} already patches many macros
-% to add these two macros. If a package or class that deals
-% with \cs{@makefntext} or \cs{@makecol} is not recognized by
-% this package, the package/class author can add these two
-% macros in his package/class.
-%
-% \subsection{Macro \cs{pdfcolfoot@switch}}
-%
-% Color commands inside footnotes should use the special
-% color stack for footnotes. Macro \cs{pdfcolfoot@switch}
-% sets this special color stack. (It can be called several
-% times). But caution, footnotes for minipages should not
-% be affected. This package patches \cs{@makefntext} for
-% this purpose.
-%
-% \subsection{Macro \cs{pdfcolfoot@current}}
-%
-% In \LaTeX\ the footnote stuff goes into box \cs{footins}
-% that is placed on the page (\cs{@makecol}).
-% Two things need consideration:
-% \begin{itemize}
-% \item The footnote area should not interfere with the normal
-%   color stack. Macro \cs{normalcolor} inside a group helps
-%   it stores the current color of the normal stack and
-%   restores it after the group.
-% \item If a footnote is broken across a page boundary, we
-%   need the latest color of the footnote area in the previous page.
-%   This is set by macro \cs{pdfcolfoot@current}.
-% \end{itemize}
-% As example the changes for \cs{@makecol} are shown (however
-% this macro is already patched by this package):
-%\begin{quote}
-%\begin{verbatim}
-%\gdef\@makcol{%
-%  ...
-%  \setbox\@outputbox\vbox{% or similar
-%    ...
-%    \color@begingroup
-%      \normalcolor
-%      \footnoterule % using normal color (black)
-%      \csname pdfcolfoot@current\endcsname
-%      \unvbox\footins
-%    \color@endgroup
-%  }%
-%  ...
-%}
-%\end{verbatim}
-%\end{quote}
-% We use \cs{csname} to call macro \cs{pdfcolfoot@current}.
-% If package \xpackage{pdfcolfoot} is not loaded, \cs{pdfcolfoot@current}
-% is not defined. In this case \cs{csname} defines the undefined
-% macro with meaning \cs{relax} and we do not get an error because
-% of undefined command.

-%% \section{Installation}
-%
-% \subsection{Download}
-%
-% \paragraph{Package.} This package is available on
-% CTAN\footnote{\CTANpkg{pdfcolfoot}}:
-% \begin{description}
-% \item[\CTAN{macros/latex/contrib/oberdiek/pdfcolfoot.dtx}] The source file.
-% \item[\CTAN{macros/latex/contrib/oberdiek/pdfcolfoot.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 pdfcolfoot.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}

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