\section{General}
There exists a new document class \LClass{pst-doc} for writing PSTricks documentations,
like this news document. It depends on the KOMA-Script document class \LClass{scrartcl}.
\LClass{pst-doc} defines a lot of special macros to create a good index. Take one of
the already existing package documentation and look into the source file. Then it will be
easy to understand, how all these macros have to be used.

When running \Lprog{pdflatex} the title page is created with boxes and inserted 
with the macro \Lcs{AddToShipoutPicture} from the package \LPack{eso-pic}. It
inserts the background title page image \Lfile{pst-doc-pdf} to use directly
\Lprog{pdflatex}.
When running \Lprog{latex} the title page
 is created with \PST\ macros.This allows to use the Perl script \Lprog{pst2pdf} or
the package \LPack{pst-pdf} or \LPack{auto-pst-pdf} or any other program/package which
supports \PS\ code in the document.

The file \Lfile{pst-tools.pro} contains additional helper functions:

/factorial { % n on stack, returns n! 
/MoverN { % m n on stack, returns the binomial coefficient m over n
/cxadd {		% [a1 b1] [a2 b2] = [a1+a2 b1+b2]

\section{\texttt{pst-node} -- version \pstnodeFV\ | \pstnodeFD}
The command \Lcs{pnode} now knows an optional argument for an offset, which
expects two values (x,y) separated by a comma:

\begin{BDef}
\Lcs{pnode}\OptArg*{\Largs{\Larga{offset}}}\Largr{\CAny}\Largb{\Larga{node name}}
\end{BDef}


\begin{LTXexample}[width=6cm]
\begin{pspicture}[showgrid](0,-2)(6,2)
\pnode{A}\psdot(A)\uput[90](A){A} 
\pnode[0,-2]{B}\psdot(B)\uput[90](B){B} 
\pnode(2,0){C}\psdot(C)\uput[90](C){C} 
\pnode[1,-2](2,0){D}\psdot(D)\uput[90](D){D} 
\pnode[2,2](3.5,0){E}\psdot(E)\uput[90](E){E} 
\end{pspicture}
