-/// Chamfering OpenSCAD Example
-/// Written by Robert Quattlebaum, 2022-12-14
-///
-/// This example shows a method for adding a chamfer to a certain
-/// class of 3D objects where the profile in the Z dimension doesn't
-/// change significantly.
-///
-/// You must specify the size of the chamfer, the height of the child
-/// and the Z-offset for the bottom of the object. You can also specify
-/// the shape of the chamfer, which can be either "cone", "curve", "curve-in",
-/// or "pyramid".
-///
-/// This process is ultimately slow, but should be faster than using minkowski.
