The package *pst-bezier* provides LaTeX-macros for Bezier splines

    * with arbitrary many interpolation points and
    * with automatically computed control points which can separately be
      changed by many options (you can set the location of some or all
      control points or you can influence the parameters for the
      automatical computation of the control points).
