TYPE: SOP
TITLE: PolySpline SOP

PolySpline fits a spline curve to a polygon or hull and outputs a polygonal
approximation of that spline. PolySpline can optionally resample the output
curve, providing control over the length and number of its segments.

Parameters:
    Group	- Subset of faces to use

    Spline Type - Spline type: Bezier, Special Bezier, Special Smooth Bezier,
                     Degree 2 Bezier, BSpline, Cardinal, or Linear

    Close	- 
        Off                   - Output spline open
        On                    - Output spline closed
        If polygon does       - Use the closure of the input face

    Division Method - 
        Standard              - Do not resample curve
        Even Length Segments  - Resample - ensure equal segment lengths
        Even X Segments       - Resample - ensure segments have equal length in x
        Even Y Segments       - Resample - ensure segments have equal length in y
        Even Z Segments       - Resample - ensure segments have equal length in z

    Segment Length - The length of the segments in the resampled curve.
	    If set to zero, segment length is calculated using the Output
	    Divisions parameter. /segsize

    Output Divisions - Number of segments in the resampled curve.  If
		       set to zero, the number of output divisions is
		       calculated using the Segment Length parameter.
		       /polydivs

    Sample Divisions - Number of spline divisions before resampling /egdedivs

    First CV Count - Number of times to repeat the first control
		     vertex, determining its multiplicity 		/first

    Last CV Count - Number of times to repeat the last control vertex,
		    determining its multiplicity 			/last

    CV Tension - Spline tension		/tension
