\section usdHydra_overview Overview

\note This library is now deprecated and will be deleted soon.

UsdHydra used to provide schemas and behaviors for creating and connecting 
shading networks based on UsdShade.

The schemas in this library have been deleted. Currently, it provides only the 
list of tokens used in the schemas, to assist in the gradual transition to the 
new-style of hydra shaders authored using the shader registry.
