[pstricks] arrow

[Jean-Michel Papy]

Dear pstricks users,

I drawn a spiral:

\begin{pspicture}(-3,-3)(3,3)
\psaxes[ticks=none]{->}(0,0)(-3,-3)(3,3)
\parametricplot[algebraic,linecolor=black,plotpoints=500]%
{-4}{4}{2*cos(t)*2.71^(-t/10)|2*sin(t)*2.71^(-t/10)}
\end{pspicture}


Question: is there a command for adding an arrow at the end of this
spiral ?

regards,

JM
