+\section{Introduction}
+
+The package \CircPackage{} is a collection of graphical elements based
+on PStricks that can be used to facilitate display of electronic
+circuit elements. For example, an equivalent circuit of a voltage
+source, its source impedance, and a connected load can easily be
+constructed along with arrows indicating current flow and potential
+differences. The emphasis is upon the circuit elements and the
+details of the exact placement are hidden as much as possible so the
+author can focus on the circuitry without the distraction of sorting
+out the underlying vector graphics.
+
+\section{Usage}
+
+\subsection{Parameters}
+
+There are specific paramaters defined to change easily the behaviour of the pst-circ
+objects you are drawing.

+
+\subsection{Tripole macros}
+
+Obviously, tripoles are not node connections. So \CircPackage{} tries its best to adjust the
+position of the tripole regarding the three nodes. Internally, the connections are done by the
+\cs{ncangle} pst-node macro. However, the auto-positionning and the auto-connections are not always
+well chosen\footnote{This is something we are working on. I think that auto-positionning and
+auto-connections should be done at PostScript level and not at PSTricks level. If someone has any
+ideas, please mail us.}, so don't try to use tripole macros in strange situations!
+
+\begin{PSideBySideExample}[xrightmargin=5.5cm](5,3)
+ \pnode(0,0){A}
+ \pnode(0,3){B}

+ \pnode(4,0.5){D}
+ /HLCBWz&\optoCoupler"(A)(B)(C)(D){$OC$}
+\end{PSideBySideExample}
+
+\subsection{Multidipole}
+
+
+
+\cs{multidipole} is a macro that allows multiple dipoles to be drawn between two specified nodes.
+\cs{multidipole} takes as many arguments as you want. \textbf{Note the \rnode{Dot}{dot} that is
+after the last dipole.}
+
+\def\HLrnode#1{\rnode{Dot2}{#1}}
+\begin{PSideBySideExample}[xrightmargin=8.5cm](8,8)
+ \pnode(0,0){A}
+ \pnode(8,8){B}
+ /HLCBWz&\multidipole"(A)(B)\resistor{$R$}%
+ \capacitor[linecolor=red]{$C$}%
+ \diode{$D$}/HLrnode&/HLCBWz."
+\end{PSideBySideExample}
+
+\ncangles[linestyle=dashed,linecolor=gray,nodesep=3pt,armA=.5cm,angleA=-90,armB=4cm,angleB=0]{->}{Dot}{Dot2}
+Important: for the time being, \cs{multidipole} takes optional arguments but does not
+restore original values. We recommand not using it.

+
+\subsection{Current intensity and electrical potential parameters}
+
+If the \HLTTc{intensity} parameter is set to \texttt{true}, an arrow is drawn on the wire
+connecting one of the nodes to the dipole. If the \HLTTc{tension} parameter is set to \texttt{true},
+an arrow is drawn parallel to the dipole.
+
+The way those arrows are drawn is set by \HLTTc{dipoleconvention} and \HLTTc{directconvention}
+parameters. \HLTTc{dipoleconvention} can take two values~: \texttt{generator} or \texttt{receptor}.
+\HLTTc{directconvention} is a boolean.
+
+\begin{PSideBySideExample}[xrightmargin=3.5cm](3,2)
+ \pnode(0,.5){A}
+ \pnode(3,.5){B}
+ \resistor[/HLCBWz&intensity",/HLCBWz&tension"](A)(B){}
+\end{PSideBySideExample}
+
+\begin{PSideBySideExample}[xrightmargin=3.5cm](3,2)
+ \pnode(0,.5){A}

+\end{PSideBySideExample}
+
+\begin{PSideBySideExample}[xrightmargin=3.5cm](3,2)

+ \pnode(3,.5){B}
+ \resistor[intensity,tension,
+ dipoleconvention=generator,directconvention=false](A)(B){}
+\end{PSideBySideExample}
+
+If \HLTTc{intensitylabel} is set to an non empty argument, then \HLTTc{intensity} is automatically
+set to true. If \HLTTc{tensionlabel} is set to an non empty argument, then \HLTTc{tension} is
+automatically set to true.
+
+\begin{PSideBySideExample}[xrightmargin=3.5cm](3,2)

+\section{Adding new components}
+
+Adding new components is not simple. As a matter of fact, because of the complex
+mechanism of \cs{multidipole}, there are multiple steps. The easiest way to proceed is
+to draw the component, send it to me (\texttt{\makeatletter
+christophe.jorssen@noos.fr\makeatother}) and I'll do the programming work regarding your
+component. Nevertheless, it can take some time\dots
+
+If you want to modify the code, you need to know the following
+things. For a dipole, you first
+need to define the following items \fvset{commandchars=/&"}

+Then, you have to make some changes in the \cs{multidipole} core code\dots In the definition
+of \Verb+\pst@multidipole+, look for the last \Verb+\ifx+ test
+\begin{Verbatim}
+ % ...
+ % Extract from \pst@multidipole
+ \else
+ \ifx\circledipole #4%
+ \let\next\pst@multidipole@circledipole
+ \else
+ \ifx\LED #4%
+ \let\next\pst@multidipole@LED
+ \else
+ % Put your modification here
+ \let\next\ignorespaces
+ \fi
+ \fi
+ \fi
+ % Extract form \pst@multidipole
+ % ...
+\end{Verbatim}
+and add (in red)
+\begin{Verbatim}
+ % ...
+ % Extract from \pst@multidipole
+ \else
+ \ifx\circledipole #4%
+ \let\next\pst@multidipole@circledipole
+ \else
+ \ifx\LED #4%
+ \let\next\pst@multidipole@LED
+ \else
+ /red&\ifx\/emph&component/_name" #4%"
+ /red&\let\next\pst@multidipole@/emph&component/_name""
+ /red&\else"
+ \let\next\ignorespaces
+ /red&\fi"
+ \fi
+ \fi
+ \fi
+ % Extract form \pst@multidipole
+ % ...
+\end{Verbatim}
+Do the same in \Verb+\pst@multidipole@+
+\begin{Verbatim}
+ % ...
+ % Extract from \pst@multidipole@
+ \else
+ \ifx\circledipole #1%
+ \let\next\pst@multidipole@circledipole
+ \else
+ \ifx\LED #1%
+ \let\next\pst@multidipole@LED
+ \else
+ /red&\ifx\/emph&component/_name" #1%"
+ /red&\let\next\pst@multidipole@/emph&component/_name""
+ /red&\else"
+ \let\next\ignorespaces
+ \pst@multidipole@output
+ /red&\fi"
+ \fi
+ \fi
+ \fi
+ % Extract form \pst@multidipole@
+ % ...
+\end{Verbatim}
+and that's it! All you have to do then is send your modified \texttt{pst-circ.tex} to
+me and it will become part of the official release of \CircPackage.
+
+\textbf{Important:} Pay attention to the comment character \Verb+%+
+at the end of lines. They are \emph{very} important in order to avoid spurious blanks.

+\section{Acknowledgements}
+
+We thank of course Manuel Luque for his original work on pst-circ and for his circuit
+drawings: this wouldn't have been possible without him. As usual, Denis Girou gave us a
+precious hand with some dark tricks of \TeX{} and PSTricks. Jean-C\^ome Charpentier
+wrote the outline of \cs{multidipole} (a story about riri, fifi and loulou\dots).
+Thanks also to Douglas Waud.
