// DESCRIPTION:
//
// Produces the MEL command "polyPrimitiveTest".
//
// This plug-in creates the following types of polygon primitives at the origin:
//
// 1) Icosahedron
// 2) Dodecahedron
// 3) Tetrahedron
// 4) Cube
// 5) Octahedron
// 6) Plane
// 7) Cylinder
// 8) Truncated Icosahedron (soccer ball)
//
// It demonstrates the creation of polygonal data. Once it is loaded, executing
// "polyPrimitiveTest <primitive_number>" in the command window will cause a polygon
// to be created at the origin.
//
// Usage:
// polyPrimitiveTest <primitive_number>
//
// Related files:
// polyPrimitiveCmd.mel
//
// Limitations:
// Newly created primitives are always placed at origin
//
// Note:
// Original implementation for OpenAlias in the jptPolyPrimitives plugin.
