+%
+% \begin{abstract}
+% The \LaTeX\ package prints a page grid in the background.
+% \end{abstract}
+%
+% \tableofcontents
+%
+% \section{Documentation}
+%
+% The package puts a grid on the paper. It was written for
+% developers of a class or package
+% who have to put elements on definite locations on a page
+% (e.g. letter class). The grid allows a faster optical check,
+% whether the positions are correct. If the previewer already
+% offers features for measuring, the package might be obsolete.
+% Otherwise it saves the developer from printing the page and
+% measuring by hand.
+%
+% \subsection{Options}
+%
+% Options are evaluated in the following order:
+% \begin{enumerate}
+% \item
+% Configuration file \xfile{pagegrid.cfg} using \cs{pagegridsetup}
+% if the file exists.
+% \item
+% Package options given for \cs{usepackage}.
+% \item
+% Later calls of \cs{pagegridsetup}.
+% \end{enumerate}
+% \begin{declcs}{pagegridsetup}\M{option list}
+% \end{declcs}
+% The options are key value options. Boolean options are enabled by
+% default (without value) or by using the explicit value \texttt{true}.
+% Value \texttt{false} disable the option.
+%
+% \subsubsection{Options \xoption{enable}, \xoption{disable}}
+%
+% \begin{description}
+% \item[\xoption{enable}:] This boolean option controls whether the page grid
+% is drawn. As default the page grid drawing is activated.
+% \item[\xoption{disable}:] It is the opposite
+% of option \xoption{enable}. It was added for convenience and
+% allows the abbreviation \texttt{disable} for \texttt{enable=false}.
+% \end{description}
+%
+% \subsubsection{Grid origins}
+%
+% The package supports up to two grids on a page allowing
+% measurement from opposite directions. As default two grids are drawn,
+% the first from bottom left to top right. The origin of the second
+% grid is at the opposite top right corner.
+% The origins are controlled by the following options.
+% The number of grids (one or two) depend on the number of these options
+% in one call of \cs{pagegridsetup}.
+% The following frame shows a paper and in its corners are the
+% corresponding options. At the left and right side alias names
+% are given for the options inside the paper.
+% \begin{quote}
+% \begin{tabular}{@{}r|@{\,}l@{\qquad}r@{\,}|l@{}}
+% \cline{2-3}
+% \xoption{left-top}, \xoption{lt}, \xoption{top-left}
+% & \vphantom{\"U}\xoption{tl} & \xoption{tr}
+% & \xoption{top-right}, \xoption{rt}, \xoption{right-top}\\
+% &&&\\
+% \xoption{left-bottom}, \xoption{lb}, \xoption{bottom-left}
+% & \xoption{bl} & \xoption{br}
+% & \xoption{bottom-right}, \xoption{rb}, \xoption{right-bottom}\\
+% \cline{2-3}
+% \end{tabular}
+% \end{quote}
+% Examples:
+% \begin{quote}
+% |\pagegridsetup{bl,tr}|
+% \end{quote}
+% This is the default setting with two grids as described previously.
+% The following setups one grid only. Its origin is the upper left
+% corner:
+% \begin{quote}
+% |\pagegridsetup{top-left}|
+% \end{quote}
+%
+% \subsubsection{Grid unit}
+%
+% \begin{description}
+% \item[\xoption{step}] This option takes a length and
+% setups the unit for the grid. The page width and page height
+% should be multiples of this unit.
+% Currently the default is \texttt{1mm}. But this might change
+% later by a heuristic based on the paper size.
+% \end{description}
+%
+% \subsubsection{Color options}
+%
+% The basic grid lines are drawn as ultra thin help lines and is only
+% drawn for the first grid.
+% Each tenth and fiftyth line of the basic net is drawn thicker in a special
+% color for the two grids.
+% \begin{description}
+% \item[\xoption{firstcolor}:] Color for the thicker lines and the arrows
+% of the first grid. Default value is \texttt{red}.
+% \item[\xoption{secondcolor}:] Color for the thicker lines and the arrows
+% of the second grid. Default value is \texttt{blue}.
+% \end{description}
+% Use a color specification that package \xpackage{tikz} understands.
+% (The grid is drawn with \xpackage{pgf}/\xpackage{tikz}.)
+%
+% \subsubsection{Arrow options}
+%
+% Arrows are put at the origin at the grid to show the grid start
+% and the direction of the grid.
+% \begin{description}
+% \item[\xoption{arrows}:] This boolean option turns the arrows on or off.
+% As default arrows are enabled.
+% \item[\xoption{arrowlength}:] The length given as value is the
+% length of the edge of a square at the origin within the
+% arrow is put as diagonal. Default is 10 times the grid unit (10\,mm).
+% The real arrow length is this length multiplied by $\sqrt2$.
+% \end{description}
+%
+% \subsubsection{Miscellaneous options}
+%
+% \begin{description}
+% \item[\xoption{double}:] The output page is doubled, one without page
+% grid and the other with page grid. Possible values are shown in the
+% following table:
+% \begin{quote}
+% \begin{tabular}{ll}
+% Option & Meaning\\
+% \hline
+% |false| & Turns option off.\\
+% |first| & Grid page comes first.\\
+% |last| & Grid page comes after the page without grid.\\
+% |true| & Same as |last|.\\
+% \meta{no value} & Same as |true|.\\
+% \end{tabular}
+% \end{quote}
+% \textbf{Note:}
+% The double output of the page has side effects.
+% All whatsits are executed twice, for example: file writing
+% and anchor setting. Some unwanted actions are catched such
+% as multiple \cs{label} definitions, duplicate entries in
+% the table of contents. For bookmarks, use package \xpackage{bookmarks}.
+% \item[\xoption{foreground}:] Boolean option, default is \texttt{false}.
+% Sometimes there might be elements on the page (e.g. large images)
+% that hide the grid. Then option \xoption{foreground} puts the grids
+% over the current output page.
+% \end{description}

+%
+% \subsection{Download}
+%
+% \paragraph{Package.} This package is available on
+% CTAN\footnote{\CTANpkg{pagegrid}}:
+% \begin{description}
+% \item[\CTAN{macros/latex/contrib/pagegrid/pagegrid.dtx}] The source file.
+% \item[\CTAN{macros/latex/contrib/pagegrid/pagegrid.pdf}] Documentation.
+% \end{description}
+%
+%
+%
+% \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 pagegrid.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{pagegrid.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 pagegrid.dtx
+%makeindex -s gind.ist pagegrid.idx
+%pdflatex pagegrid.dtx
+%makeindex -s gind.ist pagegrid.idx
+%pdflatex pagegrid.dtx
+%\end{verbatim}
+% \end{quote}
