   3 This command is adapted from the macro \verb+\pstThreeDLine+ from the package
   4 \texttt{pst-3dplot} of Herbert \textsc{Voss}%
   5 \footnote{\url{http://tug.ctan.org/tex-archive/graphics/pstricks/contrib/pst-3dplot}.}

   7 We use \texttt{\textbackslash psLineIIID[options](x0,y0,z0)(x1,y1,z1)\ldots(xn,yn,zn)},
   8 with the following possible options:
   9 \begin{itemize}
  10   \item \texttt{\Lkeyword{linecolor}=colour};
  11   \item \texttt{\Lkeyword{doubleline}=true};
  12   \item \texttt{\Lkeyword{linearc}=value}.
  13 \end{itemize}
  14 It is not possible to put arrowheads at the ends of the lines.
