/*
        This example demonstrates how to use the ConvertScriptedOp command to generate a
        legacy runtime operator from a preset-based operator definition. Since the preferred
        implementation for custom operators is now Self-Installing Custom Operator, this
        example first creates a legacy runtime operator, and then writes it to a spdl file 
        and registers the new spdl file so that we have a preset-based legacy operator to use.
        Once a preset-based legacy operator has been saved to disk and registered in Softimage, this
        example creates a new scene and runs the ConvertScriptedOp command to create a new
        runtime version of the preset-based operator.
