+\subsection{Macro \nxLcs{psellipticarc}}
+In a circle the angle is proportional to the bow: $b=r\alpha$. In an
+elliptic arc this is no more the case, which is the reason why angles are
+internally corrected by PSTricks, to get the same arc lengthts for
+different radii:

+\section{New linestyle \nxLkeyval{symbol}}
+
+Instead of drawing a continous line or curve for a series of coordinates, one
+can now out a symbol in a given size, direction, and step. This works only
+for the line style \Lkeyval{symbol}. It takes the symbol defined by the optional
+argument \Lkeyword{symbol}, which can have a single character or a octal number
+of three digits. The font is specified by the key \Lkeyword{symbolFont}, which can take
+as argument one of the valid \PS fonts or the internal \Lkeyval{PSTricksDotFont}.
+If the symbol is given by a single character then the equivilant character in
+the given font is used. The difference between two symbols is set by \Lkeyword{symbolStep}
+and the symbol rotation by \Lkeyword{rotateSymbol}. For the first symbol there
+is an additional keyword \Lkeyword{startAngle}. 
+The default values for these new
+optional keywords are:
+
