 \section sdf_overview Overview
 
 Implements scene description \em layers in USD.  In USD, a complete scene description is composed from partial scene description stored in SdfLayer objects.  The primary unit of scene description within a layer is a \em prim \em spec, represented by the SdfPrimSpec class.  A complete UsdPrim on a stage is a composition of the prim's built-in fallback values and all of the prim spec objects specified in Sdf layers.  (For an overview of prims and stages, see the \ref usd_page_front "Usd library overview".) 
 
-Use methods on an SdfLayer object to export and save a layer to a file, or to load a file from disk.  Scene description files are stored in <c>.usd</c> format (one layer per file, ascii or binary).  Other features abstracted at the layer level include undo/redo functionality and logging, which can be customized by subclassing SdfLayerStateDelegateBase .

 You should primarily work with scene description using the classes in the Usd library.  The UsdStage object not only represents a complete scene; it also knows how each of the partial scene descriptions were combined to form the complete scene.  For example, the UsdStage object has the context to know how the path of a UsdPrim object on the stage relates to the paths of each SdfPrimSpec object in each layer that contributes a partial description to the complete prim.  SdfLayer objects do not have the context to know how they relate to other layers.
