+Vaucanson-G : A LaTeX package for drawing automata and graphs
+
+Vaucanson-G is based on PSTricks and PSTricks does not generate dvi instructions but instead
+directly generate postscript commands. As a result, the drawings composed by Vaucanson-G
+are not correctly visible under a dvi previewer. A very common outcome is an unscaled drawing and
+all the labels are written at the origin.
+
+Vaucanson-G is a package of macros that allow to draw automata and graphs within 
+texts written using LaTeX.
+Nota Bene: The commands for graphs are still under construction
+and are not described yet neither below nor in the manual.
+
+The design of Vaucanson-G implements the following
+underlying philosophy: "simple" automata should be 
+described with simple commands.
+The complexity of commands (or the number of things to be remembered 
+to use them) should gradually grow with the complexity of the figure 
+composed by these commands.
+
+The following example shows how a simple automaton can be drawn 
+with commands, in which only the minimal information needed (position 
+and label of states, shape and label of transitions) is made explicit.
+
+\begin{VCPicture}{(0,-2)(6,2)}
+% states
+\State[p]{(0,0)}{A} \State{(3,0)}{B} \State[r]{(6,0)}{C}
+% initial--final
+\Initial{A} \Final{C}
+% transitions 
+\EdgeL{A}{B}{a} \ArcL{B}{C}{b} \ArcL{C}{B}{b}
+\LoopN{A}{a} \LoopS{C}{d}
+%
+\end{VCPicture}
+
+This is achieved by the implicit definition of a large number of 
+parameters that control the geometry of the figure: size of states, 
+width of lines,...
+The way these parameters can be handled and modified yields what is 
+the second feature of Vaucanson-G:
+-- the easy definition of styles for the elements of figures.
+-- the capability of handling the figures both in size and 
+        appearance without modifying them.
+
+Vaucanson-G is a set of macros that uses commands of the PSTricks package,
+due to Timothy van Zandt and that appears in the current version 
+of the LaTeX distribution.
+The knowledge of this beautiful macro package is not necessary to use
+the Vaucanson-G commands.

+\VCSG is a package that allows to draw automata within 
+texts written using \LaTeX.
+It is a set of macros that uses commands of the beautiful \PSTricks package,
+due to Timothy van Zandt\footnote{%
+   The maintenance and evolution of \PSTricks has now been taken over by H.~Voss.}
+and which is part of 
+the current \LaTeX\ distribution.
+\VCSG is the result of the experience gained in composing the several
+hundreds of 
+figures in the book \emph{El\'ements de th\'eorie des automates} 
+(\cite{Sak01}) and in several other papers and conferences slides
+of the authors.
+
+The design of \VCSG implements the following
+underlying philosophy:
+\begin{enumerate}
+    \item  `simple' automata should be 
+described with simple commands.
+
+    \item Every element of a figure can easily be given a style 
+    (which differs from the implicit one).
+
+    \item  The complexity of commands (or the number of things to be remembered 
+to use them) should gradually grow with the complexity of the figure 
+composed by these commands.
+
+    \item  It should be possible to handle the figures both in size and 
+        appearance without modifying them.
+\end{enumerate}
+
+The following example\footnote{%
+    somewhat artificial but which exhibits most of the simple commands.}
+shows how a simple automaton can be drawn 
+with commands, in which only the minimal information needed (position 
+and label of states, shape and label of transitions) is made explicit.

+
+The objectives of \VCSG are achieved by the implicit definition of a 
+large number of  
+parameters that control the geometry of the figure: size of states, 
+width of lines, \etc 
+and by the definition of commands that allow to 
+handle and modify these parameters.
+
+The following pages gives a presentation of \VCSG that 
+gradually introduces the commands from the basic ones that allow 
+to draw already a good deal of automata to the more 
+sophisticated ones that are used to modify the internal parameters.

+\section{Downloading and using the package}\label{sec.d}
+
+
+The \VCSG package is downloadable from the URL:
+
+\texttt{/igm.univ-mlv.fr/\URLtilde lombardy/Vaucanson-G/}
+
+\noindent
+and consists, beside the present manual, in seven files:
+the wrapper \texttt{vaucanson-g.sty}, 
+the main macro file \texttt{VauCanSon-G.tex}, 
+and five other ancillary files\footnote{%
+   {\it Cf.} Section~\ref{sec.mod} for an explanation on the role of 
+   these files.}
+for options, patches and colors:
+\texttt{VCPref-default.tex}, 
+\texttt{VCPref-slides.tex},
+\texttt{VCPref-beamer.tex},
+\texttt{VCPref-mystyle.tex},
+\texttt{VCColor-names.def}
+\index{VCPref-default}%
+\index{VCPref-slides}%
+\index{VCPref-beamer}%
+\index{VCPref-mystyle}%
+\index{VCColor-names.def}%
+that should all be stored in the user's \texttt{texinputs} directory.
+
+A \LaTeX\ file that will use \VCSG macros should contain the call to 
+the wrapper in the preamble:
+
+\verb+\usepackage{vaucanson-g}+ 
+
+The \VCSG commands are to be used in a \LaTeX\ file and not in a plain \TeX\ 
+file for it uses the macro \verb+\newcommand+ that does not exist in \TeX.
+
+\VCSG is based on the \PSTricks package.
+The knowledge of this macro package,
+described in \cite{Girou94}, \cite[Ch.~4]{GRM97}, 
+\cite{GRMRV07}, \cite{Voss07},
+is not necessary to use the \VCSG commands.\footnote{%
+   It probably helps in understanding how they are built, and is 
+   useful if one wants to make figures that consists of automata but 
+   also contains other graphical elements
+   ({\it cf.} Section~\ref{sec.pla}).}
+On the contrary, \VCSG has somehow be written to save on it.
+In particular, the \VCSG commands follow the simple (and rigid) 
+syntax of \LaTeX\ commands concerning the way the arguments are 
+specified, and not the much more flexible syntax of \PSTricks itself.
+
+
+But the call to \PSTricks commands has the consequence that \VCSG 
+commands generate pieces of \texttt{Postscript} files which in turn 
+has two main outcomes\footnote{%
+    which a user should have in mind before sending complaint and 
+    request.}:
+    \begin{itemize}

+\section{Basic commands}\label{sec.b}
+
+An automaton is a \emph{labelled directed graph} where some of the vertices, 
+called \emph{states}, are distinguished to be \emph{initial} or 
+\emph{final} states.
+The basic commands allow then \emph{to define} and \emph{to draw} 
+states, to give them the quality of being initial or final and to give 
+them \emph{labels} as well.
+They allow to draw \emph{transitions} 
+between states (that have been defined before);
+there are 3 kinds of transitions: \emph{(straight) edges}, \emph{arcs} and 
+\emph{loops}.
+
+These commands have to be put in an environment that defines \emph{a 
+picture}.
+All graphical parameters of these elements (size, line width, \etc ) 
+are kept implicit when using these basic commands.
+

+
+The~$x_{i}$ and~$y_{i}$ are either \emph{length} or \emph{numbers} in 
+which case they represent the corresponding length in centimeter (which 
+is the implicit length unit used in \VCSG).
+The length of the box is thus~$x_{1}-x_{0}$, its 
+height~$y_{1}-y_{0}$, its \emph{baseline point} stands at the middle 
+of the height.
+As usual in \TeX, a picture may well ``contain'' an element that 
+actually lays outside of the box.
+
+Note that the environment has only \emph{one} argument consisting of \emph{two} 
+point coordinates enclosed in adjacent parentheses.

+\subsection{The \texttt{State} commands}\label{subsec.sta}
+\index{State}
+
+States are represented by circles, inside which an information (the 
+\emph{Label}) can be written.
+Every state is given a \emph{Name} which is used then internally in the figure to describe the 
+transitions that start from it or end at it.

+There is no reason indeed for an author to ``program'' the drawing of 
+an automaton at the size it will appear on his, or her, 
+paper. 
+On the contrary, he, or she, is likely to sketch the figure on a 
+ruled paper at a larger scale, giving the points to be defined integer 
+coordinates.
+And then she, or he, will try to put the figure within the text at a 
+reasonable size and thus would like to scale it.
+
+The parameter \verb+\VCScale+ contains this global scaling factor and is
+initialized to the value \verb+0.6+ , which corresponds to the 
+command \verb+\MediumPicture+.
+Three other commands: 
+\verb+\TinyPicture+ ,
+\verb+\SmallPicture+ and

+There are \emph{three preset sizes} for the states, that are called by the 
+commands \verb+\SmallState+, \verb+\MediumState+ and 
+\verb+\LargeState+, that call for states of diameter 
+\verb+0.6cm+, \verb+0.9cm+ and \verb+1.2cm+ respectively.
+The implicit size, \ie the one that states have if no explicit command 
+is given, is \verb+\MediumState+.
+The ``small'' states are not likely to receive labels, unless their 
+size are changed by other commands.

+%Independently of the preset size --- in this instance, of the \emph{height} --- 
+One can draw states which will be called \emph{variable states} and whose 
+\emph{width} is variable and \emph{fits the width of the 
+label}.\footnote{%
+   This makes sense for long labels and it may be the case then that 
+   the label is not a mathematical variable or expression any more 
+   but simple text.
+   In order to write labels in \TeX\ LR mode, the easiest way is to 
+   write it as the parameter of a $\backslash$\texttt{text} command, 
+   provided the \texttt{amsmath} package has been called in the 
+   preamble.}

+\index{StateVar}

+Note that the current version of \VCSG uses a trick to make these 
+states with adaptable width.
+They look like Egyptian cartouches but they are indeed 
+\emph{rectangles} which can be observed when transitions reach these 
+states in an oblique way.
+
+Arcs between variable states of different width will look asymmetric 
+and often ungainly.
+Other loops than ``north'' and ``south'' loops should not be drawn 
+around variable states. Moreover, in order to draw loops that have the same appearance as loops
+around standard states, one should use 
+\verb+\LoopVarN+ or \verb+\LoopVarS+
+that have the same syntax as \verb+\LoopN+ or \verb+\LoopS+.
+\index{LoopVarN}\index{LoopVarS}
+Another possibility is to call the \verb+\VarLoopOn+ command to make 
+all the subsequent loops suited to variable states.
+Switching back to `normal' loops is made by \verb+\VarLoopOff+.
+\index{VarLoopOn}
+\index{VarLoopOff}
+
+For the same reason, it is \emph{not possible} to make a variable
+state initial or final with diagonal arrows ($ne$, $nw$, $se$, $sw$).

+\section{Composing a picture}\label{sec.com}
+
+The commands described above allow to define most of the figures 
+representing automata in any textbook or technical paper.
+Before turning to more sophisticated commands that are used 
+for less than 5 percent of the elements and that appear in less than 
+10 percent of the figures, let us turn to few commands that help in 
+composing the figures.
+
+
+%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Structuring the automaton: The \texttt{VCPut} command}\label{subsec.rpu}
+
+In many automata, a same pattern in states, and also in edges, is 
+reproduced several times in the figure.
+The idea is not to try to ``program'' these regular patterns but to 
+allow the use of the ``copy-and-paste'' operations in the source 
+file as much as possible, with minimum corrections afterwards.
+This will be achieved easily with the help of the  
+command~\verb+\VCPut+.\index{VCPut}

+\end{minipage}%
+

+\noi
+Note that this command is taken directly from \PSTricks but uses \VCSG's syntax.
+%the special syntax of that command which is taken directly from 
+%PSTricks: the first argument ($x$,$y$)
+%\emph{is not} put inside braces.
+%There should not be any space before, after, and inside the 
+%parentheses.
+
+Of course the commands that are to be put as the second argument 
+of~\verb+\VCPut+ are the defining states commands, with possibly  
+other~\verb+\VCPut+ inside. 
+The structuration of the figure \textit{via} the use of~\verb+\VCPut+
+commands does not only save typing.
+It makes also easier the tuning of the figure, and the reusability of 
+its parts.
+
+In the example below, the two~\verb+\VCPut+ are used to place the 
+two parts of the automaton.

+\section{Modifying and setting the parameters}\label{sec.mod}
+
+The reason why the commands in \VCSG are simple and concise is that 
+all the parameters that control the geometry (size, angles, 
+\ldots) and the drawing (line width, line style, line color, \ldots) 
+of the states and transitions in an automaton are preset by \VCSG and 
+can be kept implicit.
+But there are two instances where a user may want to modify these 
+preset values.
+
+The first case is when one needs to tune a parameter in order to make 
+the figure more readable, or nicer. 
+Such a case has already been considered in 
+sections~\ref{subsec.edg}, \ref{subsec.arc} and~\ref{subsec.loo}, 
+where the parameter \textsl{Pos}   
+that controls the position of the label of a transition along the 
+edge has been modified with an optional argument. 
+The parameters that will be considered in this section are not 
+optional parameters of already defined commands but parameters that 
+are set with their own commands.
+
+The other case where a user will change the implicit parameters of 
+a figure or, more likely, of a set of figures, is when he (or she) 
+will be in the position to change completely the ``style'' of the 
+drawing.
+For instance, a same set of figures may be used in a paper \emph{and} in a 
+series of slides for the presentation of the paper.
+Of course, the figures have to be set at a larger scale, probably 
+in colour, and possibly with different relative sizes of the elements.
+
+We begin with the description of the options for the latter case, 
+which is by far simpler. We then explain the syntax convention taken 
+to coin the names of the many commands that control the many 
+parameters.
+Then comes the list of these parameters, for scaling first, then for 
+states, for transitions, and finally for the fine tuning of 
+some details of the drawing.
+
+%%%%%%%%%%%%%%%%%%%%%%
+\subsection{Style files}\label{sec.sty-fil}
+
+The package \VCSG is loaded with default values that are all set up 
+in the file \verb+VCPref-default.tex+~. 
+\index{VCPref-default}%
+\index{VCPref-slides}%
+\index{VCPref-beamer}%
+\index{VCPref-mystyle}%
+The package comes with two other styles, in particular one for 
+drawing slides. 
+The normal way of using the different style files is to call the 
+wrapper \texttt{vaucanson-g} with an option:

+% \texttt{slides}.}%
+% \stepcounter{footnote}%
+% \medskip
+% \smallskip 
+
+Although it is not the normal usage,
+it is also possible to change style in the course of the text by 
+loading a style file with an \verb+\input+ command. In this
+case, it is recommended to reset all parameters by calling
+\verb+VCPref-default.tex+.

+\noi 
+% In order to be effective, the command \verb+\Set+\textsl{Param} has to be 
+% called \emph{outside} a picture.
+The command \verb+\Set+\textsl{Param} can be 
+called \emph{outside} a \verb+\VCPicture+ environment, in which case 
+it will be effective in all subsequent figures, until a new setting 
+of the same parameter.
+Its natural place, if it is considered as a modification of the style,
+is in the preamble, after the call to the package \VCSG.
+If the command \verb+\Set+\textsl{Param} is
+called \emph{inside} a \verb+\VCPicture+ environment, its effect will 
+be restricted to that figure.
+
+Such parameters will be called \emph{adjustable parameters} in the 
+sequel.
+
+Note that in the case where \verb+\+\textsl{Param} is a value
+(a \emph{length} or a \emph{scale}), the 
+value of \textsl{Val} in \verb+\Chg+\textsl{Param}\verb+{+\textsl{Val}\verb+}+ is a 
+\emph{coefficient} which is applied to the style value of \verb+\+\textsl{Param}
+defined with \verb+\Set+\textsl{Param}\verb+{+\textsl{Val}\verb+}+.
+Therefore, in this case, \verb+\Rst+\textsl{Param} is equivalent to 
+\verb+\Chg+\textsl{Param}\verb+{1}+. 
+
+The other parameters, as those that define the ``dimmed'' style,
+are called \emph{preset parameters}.
+%Belong to that class those parameters that can be ``adjusted'' by means 
+%of an optionnal argument, \eg \verb+\EdgeLabelPosit+ which gives 
+%the implicit position of the label on an edge.
+
+There is finally a class of parameters that fall in between the 
+adjustable and the preset ones, those for which several values are 
+``preset'' but that can be given other values. 
+%For instance, the scale of the 
+%picture  is fixed by the parameter \verb+\VCScale+: it can given 
+%the preset values \verb+\NormalScale+, \verb+\SmallScale+ or 
+%\verb+\LargeScale+ 
+%by means of the command \verb+\NormalPicture+, \verb+\SmallPicture+ 
+%or \verb+\LargePicture+ respectively, or given any chosen value 
+%\textsl{Val} by the command \verb+\FixVScale{+\textsl{Val}\verb+}+ .

+between the transition and the label of the state.
+
+The parameter \textit{EdgeLabelSep} controls the distance between the 
+box that contains the label of the transition (built by \LaTeX) and 
+the transition.
+
+
+\paragraph{Edge preset parameters}
+~
+A first class of preset parameters deals with the definition of ``dimmed'' edges.
+
+\begin{center}
+\begin{tabular}{c|c|c|}
+Parameter & Default value\\
+\hline
+\textit{DimEdgeLineStyle} & \texttt{solid} \\
+\hline
+\textit{DimEdgeLineColor} & \texttt{gray} \\
+\hline
+\textit{DimEdgeLineCoef} & \texttt{1.2} \\
+\hline
+\textit{DimEdgeLabelColor} & \texttt{gray}\\
+\hline
+\end{tabular}
+\end{center}
+\index{DimEdgeLineStyle}\index{DimEdgeLineColor}\index{DimEdgeLineCoef}\index{DimEdgeLabelColor}
+
+The style of dimmed edges can be fixed by the command
+\\\verb+\FixDimEdge{+\textit{LineStyle}\verb+}{+\textit{LineColor}\verb+}{+\textit{LineCoef}%
+\verb+}{+\textit{LabelColor}\verb+}+.
+\index{FixDimEdge}
+\medskip
+
+The style of the border of edges (in mode \verb+\EdgeBorder+),
+is defined by two parameters~:
+\begin{center}
+\begin{tabular}{c|c|c|}
+Parameter & Default value\\
+\hline
+\textsl{EdgeLineBorderCoef} & \texttt{2} \\
+\hline
+\textsl{EdgeLineBorderColor} & \texttt{white} \\
+\hline
+\end{tabular}
+\end{center}
+\index{EdgeLineBorderCoef}\index{EdgeLineBorderColor}
+
+\verb+\EdgeLineBorderCoef+ is a coefficient applied to \verb+\EdgeLineWidth+,
+that gives the width of the border.\\The style of borders of edges can
+be fixed by the command \verb+\FixEdgeBorder{+\textsl{Coef}\verb+}{+\textsl{Color}\texttt{\}}.
+\index{FixEdgeBorder}
+\medskip
+
+The width of the double line of (in mode \textsl{EdgeLineDouble}),
+is defined by two parameters, that give the width of each of both lines
+and the distance between them. These values are coefficients that are
+applied to \textsl{EdgeLineWidth}.
+
+\begin{center}
+\begin{tabular}{c|c|c|}
+Parameter & Default value\\
+\hline
+\textsl{EdgeLineDblCoef} & \texttt{0.5} \\
+\hline
+\textsl{EdgeLineDblSep} & \texttt{0.6} \\
+\hline
+\end{tabular}
+\end{center}
+\index{EdgeLineDblCoef}\index{EdgeLineDblSep}
+
+These values can be fixed by the command \verb+\FixEdgeLineDouble{+\textsl{Coef}\verb+}{+\textsl{Sep}\texttt{\}}.
+\index{FixEdgeLineDouble}
+
+\subsection{Advanced parameters}
+These parameters can be changed by using the usual command \verb+\renewcommand+
+(or \verb+\setlength+, when the parameter is a length).
+
+As it has already be mentionned, the preset commands that set
+the diameter of states control
+parameters for drawing edges (the length of initial and final arrows or
+the curvature of loops). Their values are:
+\begin{center}
+\begin{tabular}{c|c|c|c|}
+\textit{X} & \verb+\ArrowOn+\textit{X} & \verb+\LoopOn+\textit{X} & \verb+\CLoopOn+\textit{X}\\
+\hline
+\verb+LargeState+ & \texttt{1.3} & \texttt{5.8} & \texttt{6}\\
+\hline
+\verb+MediumState+ & \texttt{1.5} & \texttt{5.8} & \texttt{8}\\
+\hline
+\verb+SmallState+ & \texttt{1.7} & \texttt{5.8} & \texttt{12}\\
+\hline
+\verb+VariableState+ &  & \texttt{5.1} & \texttt{5.2}\\
+\hline
+\verb+VerySmallState+ & \texttt{5} & \texttt{15} & \\
+\hline
+\end{tabular}
+\end{center}
+\index{ArrowOnState}\index{LoopOnState}\index{CloopOnState}
+
+\textit{ArrowOnX} is the coefficient that is applied to the radius of the state
+to obtain the length of initial or final arrows. \textit{LoopOnX} and 
+\textit{CLoopOnX}
+is the eccentricity of loops and closed loops respectively.
+
+Another parameter determines whether the dimension of states
+refer to the middle, the inner or the outer side of the boundary.
+There exist one parameter for classical states and one
+for states with double line:
+\begin{center}
+\begin{tabular}{c|c|}
+Parameter & Default value \\
+\hline
+\verb+\StateDimen+ & \texttt{outer} \\
+\hline
+\verb+\StateDblDimen+ & \texttt{middle} \\
+\hline
+\end{tabular}
+\end{center}\index{StateDimen}{\index{StateDblDimen}
+The possible values are \texttt{inner}, \texttt{outer} or \texttt{middle}.

+\paragraph{Transition adjustable geometric parameters}
+~
+All these parameters are adjustable. That means there
+exist commands as \verb+\Set+\textsl{Parameter}, \verb+\Chg+\textsl{Parameter}
+and \verb+\Rst+\textsl{Parameter}.
+
+Arcs between states are characterized by some adjustable parameters:
+
+\begin{center}
+\begin{tabular}{c|c|c|c|}
+\textsl{X} & \textsl{XAngle} & \textsl{XCurvature} & \textsl{XOffset} \\

+\hline
+\end{tabular}
+\end{center}
+\index{ArcAngle}\index{ArcCurvature}\index{ArcOffset}
+
+\medskip
+Except the curvature that depends on the size of states,
+parameters that define loop,
+the degree of opening and the offset, are adjustable parameters.
+
+\begin{center}
+\begin{tabular}{c|c|c|}
+\textsl{X} & \textsl{XAngle} (degrees) & \textsl{XOffset} \\
+\hline
+\textsl{Loop} & \texttt{30} & \texttt{0}pt\\

+Likewise, one can modify the style of arrows, that are defined by 
+three adjustable parameters~:
+
+
+\begin{center}
+\begin{tabular}{c|c|}
+Parameter & Default value \\
+\hline
+\textsl{EdgeArrowStyle} & \texttt{->} \\
+\hline
+\textsl{EdgeArrowWidth} & \texttt{5}pt \\
+\hline
+\textsl{EdgeArrowLengthCoef} & \texttt{1.4}  \\
+\hline
+\textsl{EdgeArrowInsetCoef} & \texttt{0.1}  \\
+\hline
+\end{tabular}
+\VCDraw{%
+\begin{VCPicture}{(-4,-2)(4,2)}
+\pspolygon*(-1,-1)(0,1)(1,-1)(0,-.3)

+\end{VCPicture}
+}
+\end{center}
+\index{EdgeArrowStyle}\index{EdgeArrowWidth}%
+\index{EdgeArrowLengthCoef}\index{EdgeArrowInsetCoef}
+
+The {\em length} and the {\em inset} of arrows are given by 
+coefficients that are applied to the {\em width}. 
+There exists some other (non adjustable) parameters to define arrows 
+in special cases: 
+\verb+\EdgeArrowRevStyle+ is equal to \texttt{<-}, to draw transition 
+in reverse mode; for edges with double lines, the size of 
+arrows is a little bit more large. 
+It is defined by \verb+\EdgeDblArrowWidth+
+and \verb+\EdgeDblArrowLengthCoef+ that are respectively equal to 
+\texttt{5.5}pt and \texttt{1.7}. 
+
+\medskip
+\noi
+Zigzag edges are characterized by some adjustable parameters:
+
+\begin{center}
+\begin{tabular}{c|c|}
+Parameter & Default value \\
+\hline
+\textsl{ZZSize} & \texttt{0.9}cm \\
+\hline
+\textsl{ZZLineWidth} & \texttt{1.7}  \\
+\hline
+\end{tabular}
+\end{center}
+\index{ZZSize}\index{ZZlineWidth}
+
+\textsl{ZZSize} is the apparent diameter of the zigzag and \textsl{ZZLineWidth}
+is a coefficient that is applied to \textsl{EdgeLineWidth} and gives
+the width of the line.
+
+\paragraph{Transition preset parameters}
+~
+The default position of labels on transitions depends on the type of transition.
+For instance, on edges, this position is given by the variable \verb+\EdgeLabelPosit+
+that is equal to $0.45$. The first column of the following array gives these values
+for every transition.
+
+\begin{center}
+\begin{tabular}{c|c|c|}
+\textsl{X} & \verb+\+\textsl{X}\texttt{LabelPosit} & \verb+\+\textsl{X}\texttt{LabelRevPosit} \\
+\hline
+\texttt{Edge} & \texttt{.45} & \texttt{.55}\\
+\hline
+\texttt{Arc} & \texttt{.4} & \texttt{.6}\\
+\hline
+\texttt{LArc} & \texttt{.4} & \texttt{.6}\\
+\hline
+\texttt{Loop} & \texttt{.25} & \texttt{.75}\\
+\hline
+\texttt{CLoop} & \texttt{.25} & \texttt{.75}\\
+\hline
+\texttt{Init} & \texttt{.1} & \texttt{.9}\\
+\hline
+\texttt{Final} & \texttt{.9} & \texttt{.1}\\
+\hline
+\end{tabular}
+\end{center}
+
+When the reverse mode is on, the position of label is given by
+variables that correspond to the second column, as \verb+\EdgeLabelRevPosit+ for instance.
+For the same type of transition, the sum of both variables
+that defined position for straight and reverse arrows should
+be equal to $1$ (if one wants to keep the same appearance when using
+the \verb+ReverseArrow+ command).
+
+These parameters can be modified with a \verb+\renewcommand+.
+
+%%%%%%%%%%%%%%%%%%%%%%
+\section{Using ``plain'' \PSTricks commands}
+\label{sec.pla}
+\VCSG is a set of macros based on \PSTricks. It is therefore
+fully compatible with \PSTricks instructions.
+Actually, the \verb+VCPicture+ environment is a specialization
+of the \verb+pspicture+ environment; more, every state in \VCSG
+is a \PSTricks node and every transition (loop, edge, arc)
+is a node connection.
+
+The following example shows how \VCSG commands can be mixed
+with plain \PSTricks commands. For further explanation on
+\PSTricks, we refer to~\cite{Girou94,GRM97,GRMRV07,Voss07}.

+\section{Version history}
+
+A first version of the package, which would be numbered 0.1, was 
+called \emph{Vaucanson} and used by the authors in their papers 
+between 2000 and 2003.
+But, at the same time, the authors were involved, in cooperation with
+the LRDE at EPITA, in the design of a \texttt{C++} platform for 
+programming automata, for which it was decided that there would be no 
+better name than Vaucanson as well.
+We thus turned the name of the package for drawing automata to \VCSG.
+% The name of every \textbf{file} of the library has been changed accordingly.
+% No name of \textbf{command} in the package has been changed.
+
+Version 0.2 was issued in May 2003 and made available on the web 
+together with this user's manual first version.
+A series of bug corrections and slight improvements made us switch at 
+some point to version 0.3.
+
+Just before sending the package to CTAN, we undertook a full review of 
+the code and updated the manual accordingly. 
+We call it version 0.4.
+It is the last release before a completely new version of the 
+package, with many more options , which is currently under work.
