+% 
+% \section{Introduction}
+% The \texttt{fgruler} is an abbreviation for the \emph{foreground ruler}.
+% This package draws a horizontal and a vertical ruler on the foreground of every (or a given) page at absolute position.
+% In this way, you can check the page layout dimensions.
+% 
+% \medskip\noindent
+% Besides, you can draw various rulers in the text, too.
+% 
+% \medskip\noindent
+% The \texttt{fgruler} package requires the services of the following packages: \texttt{kvoptions}, \texttt{etoolbox}, \texttt{xcolor}, \texttt{graphicx}, \texttt{eso-pic}.
+% 
+% \section{Loading package}
+% Load the package with
+% \begin{flushleft}
+% \commandinline|\usepackage[!<options>!]{fgruler}|
+% \end{flushleft}
+% or
+% \begin{flushleft}
+% \commandinline|\usepackage{fgruler}|\\
+% \commandinline|\setfgruler{!<options>!}|
+% \end{flushleft}
+% The \verb|\setfgruler| command is usable in the \texttt{document} environment, too.
+% 
+% \section{Options}\label{sec:options}
+% By default, the \texttt{fgruler} package draws a square ruler on the foreground of every page. The following package options set the parameters of these rulers.
+% \begin{description}
+% \item\commandinline|unit=!<unit>!|\\
+% Ruler unit.
+% \begin{description}
+% \item\commandinline|!<unit>!| values:\\
+% \commandinline|cm| Metric ruler (centimeter). Default value.\\
+% \commandinline|in| English ruler (inch).
+% \end{description}
+% 
+% \item\commandinline|type=!<type name>!|\\
+% Origin and directions.
+% \begin{description}
+% \item\commandinline|!<type name>!| values:\\
+% \commandinline|upperleft | Origin: upper left corner. Directions: down and right. Default value.\\
+% \commandinline|upperright| Origin: upper right corner. Directions: down and left.\\
+% \commandinline|lowerleft | Origin: lower left corner. Directions: up and right.\\
+% \commandinline|lowerright| Origin: lower right corner. Directions: up and left.\\
+% \commandinline|none      | Not drawing ruler.
+% \end{description}
+% 
+% \item\commandinline|hshift=!<length>!|\\
+% Horizontal shift.
+% The shift direction is right, if the \commandinline|!<type name>!| is \verb|upperleft| or \verb|lowerleft|, otherwise it is left.
+% Default: \verb|hshift=0cm|
+% 
+% \item\commandinline|vshift=!<length>!|\\
+% Vertical shift.
+% The shift direction is down, if the \commandinline|!<type name>!| is \verb|upperleft| or \verb|upperright|, otherwise it is up.
+% Default: \verb|vshift=0cm|
+% 
+% \item\commandinline|color=!<color name>!|\\
+% Ruler color (see \texttt{xcolor} package).
+% Default: \verb|color=black|
+% 
+% \item\commandinline|numsep=!<length>!|\\
+% Separation between number and ruler.
+% Default: \verb|numsep=3pt|
+% 
+% \item\commandinline|markthick=!<length>!|\\
+% Mark thickness.
+% Default: \verb|markthick=0.4pt|
+% 
+% \item\commandinline|marklength=!<length>!|\\
+% Mark length at integer units:
+% {\fgrulernoborderline\fgrulercaptioncm{}\fgrulerthickcm{}{}{1pt}\fgrulercolorcm{}{}{red}\ruler{rightup}{3cm}}\quad
+% Default: \verb|marklength=2mm|\\
+% See the length of the other marks in Section \ref{sec:additional}.
+% 
+% \item\commandinline|numfont=!<font type>!|\\
+% Number font type.
+% You can use this option only in \verb|\setfgruler| command.\\
+% Default: \verb|numfont=\scriptsize\sffamily|
+% 
+% \item\commandinline|showframe| or \commandinline|showframe=true|\\
+% It draws visible frames for the text and margin area, and lines for the head and foot.
+% Their color and thickness are determined by the \texttt{color} and the \texttt{markthick} options.
+% 
+% \item\commandinline|showframe=false|\\
+% It deactivates the \texttt{showframe} option.
+% 
+% \item\commandinline|nonefgrulers|\\
+% It kills all of the rulers on the foreground, including also those, which are generated by \verb|\fgruler| (see Section \ref{sec:givenpage}).
+% But the rulers, which were drawn by \verb|\ruler| and \verb|\squareruler| (see Section \ref{sec:intext}), do not disappear.
+% Furthermore it deactivates the \texttt{showframe} option, too.
+% In this case the \texttt{fgruler} package does not load the \texttt{eso-pic} package.
+% This option works only in preamble.
+% 
+% It is recommended to use in two cases:
+% \begin{itemize}
+% \item To draw rulers only in text, there is no need for the checking function.
+% \item To halt the checking function temporarily.
+% \end{itemize}
+% 
+% The \texttt{type=none} is not identical with \texttt{nonefgrulers} option. The differences:
+% \begin{itemize}
+% \item \texttt{type=none} does not kill the \verb|\fgruler| command and the \texttt{showframe} option.
+% \item \texttt{type=none} is alterable in any point of the document.
+% \item \texttt{type=none} works in document environment, too.
+% \item The \texttt{fgruler} package loads the \texttt{eso-pic} package, if you use the \texttt{type=none} option without \texttt{nonefgrulers}.
+% \end{itemize}
+% \end{description}
+% 
+% \section{Drawing square rulers on the foreground of a given page}\label{sec:givenpage}
+% \begin{description}
+% \item\commandinline|\fgruler[!<unit!>]{!<type name>!}{!<hshift>!}{!<vshift>!}|\\
+% It draws a square ruler on the foreground of that page, where this command is expanded.
+% You can use more \verb|\fgruler| commands in the same page.
+% 
+% The package options (see Section \ref{sec:options}) also work on this command, except for \texttt{unit}, \texttt{type}, \texttt{hshift} and \texttt{vshift}, since these are the parameters of the \verb|\fgruler|.
+% 
+% If you use \texttt{nonefgrulers} option in preamble, then this command is effectless.
+% \begin{description}
+% \item\commandinline|!<unit!>| options:\\
+% \commandinline|cm| Metric ruler (centimeter). Default option.\\
+% \commandinline|in| English ruler (inch).
+% 
+% \item\commandinline|!<type name!>| parameters:\\
+% \commandinline|upperleft | Origin: upper left corner. Directions: down and right.\\
+% \commandinline|upperright| Origin: upper right corner. Directions: down and left.\\
+% \commandinline|lowerleft | Origin: lower left corner. Directions: up and right.\\
+% \commandinline|lowerright| Origin: lower right corner. Directions: up and left.
+% 
+% \item\commandinline|!<hshift>!|
+% Horizontal shift.
+% The shift direction is right, if the \commandinline|!<type name>!| is \verb|upperleft| or \verb|lowerleft|, otherwise it is left.
+% 
+% \item\commandinline|!<vshift>!|
+% Vertical shift.
+% The shift direction is down, if the \commandinline|!<type name>!| is \verb|upperleft| or \verb|upperright|, otherwise it is up.
+% 
+% \item Example:
+% \verb|\fgruler[in]{upperright}{1in}{2.5in}|
+% \end{description}
+% \end{description}
+% 
+% \section{Drawing rulers in the text}\label{sec:intext}
+% \begin{description}
+% \item\commandinline|\ruler[!<unit!>]{!<type name>!}{!<length>!}|\\
+% It draws a horizontal or a vertical ruler.
+% The bottom of the ruler is aligned to the baseline of the surrounding text.
+% The package options (see Section \ref{sec:options}) do not work on this command.
+% \begin{description}
+% \item\commandinline|!<unit!>| options:\\
+% \commandinline|cm| Metric ruler (centimeter). Default option.\\
+% \commandinline|in| English ruler (inch).
+% 
+% \item\commandinline|!<type name!>| parameters:\\

+% \commandinline|rightup   | Direction: right. The numbers are on the up side.\\
+% \commandinline|leftdown  | Direction: left. The numbers are on the down side.\\
+% \commandinline|leftup    | Direction: left. The numbers are on the up side.
+% 
+% \item\commandinline|!<length>!|
+% Ruler length.
+% 
+% \item Example:
+% \verb|\ruler{rightdown}{5cm}|
+% \ruler{rightdown}{5cm}
+% \end{description}
+% 
+% \item\commandinline|\ruler*[!<unit!>]{!<type name>!}{!<length>!}|\\
+% It works like \verb|\ruler|, but the top of the ruler is aligned to the baseline of the surrounding text.
+% 
+% Example:
+% \verb|\ruler*{rightdown}{5cm}|
+% \ruler*{rightdown}{5cm}
+% 
+% \item\commandinline|\squareruler[!<unit!>]{!<type name>!}{!<width>!}{!<height>!}|\\
+% It draws a square ruler.
+% The bottom of the square ruler is aligned to the baseline of the surrounding text.
+% The package options (see Section \ref{sec:options}) do not work on this command.
+% \begin{description}

+% 
+% Example:
+% \verb|\squareruler*{upperleft}{5cm}{1cm}|
+% \squareruler*{upperleft}{5cm}{1cm}
+% 
+% \item\commandinline|\rulerparams{!<markthick>!}{!<numfont>!}{!<color>!}{!<marklength>!}{!<numsep>!}|\\
+% It sets the parameters of the rulers, which are drawn by \verb|\ruler| or \verb|\squareruler|. 
+% If an argument is empty, then that parameter will not be changed.
+% \begin{description}

+% \end{description}
+% 
+% \item\commandinline|\rulernorotatenum|\\

+% \end{description}
+% 
+% \section{Additional setting commands}\label{sec:additional}
+% The following commands can work on all of the rulers, which are drawn by \texttt{fgruler} package.
+% \begin{description}
+% \item\commandinline|\fgrulerstartnum{!<num>!}|\\
