* Add the line:
*
* use <knurledFinishLib_v2.scad>
*
* in your OpenSCAD script and call either...
*
* knurled_cyl( Knurled cylinder height,
* Knurled cylinder outer diameter,
* Knurl polyhedron width,
* Knurl polyhedron height,
* Knurl polyhedron depth,
* Cylinder ends smoothed height,
* Knurled surface smoothing amount );
*
* ...or...
*
* knurl();
*
* If you use knurled_cyl() module, you need to specify the values for all and
*
* Call the module ' help(); ' for a little bit more of detail
* and/or take a look to the PDF available at http://www.thingiverse.com/thing:9095
* for a in depth descrition of the knurl properties.
