+// Api categories
+// --------------
+// Enumerates the categories of APIs. These correspnd to the *_api.h files in
+// this directory. One API may implement one or more actual interfaces.
+//
+// For PROXIED_APIs, these also correspond to *_Proxy objects. The proxied ones
+// define factory functions for each of these classes. UNPROXIED_APIs are ones
+// that exist in the webkit/plugins/ppapi/*_impl.h, but not in the proxy.
+PROXIED_API(PPB_Audio)
+// AudioConfig isn't proxied in the normal way, we have only local classes and
+// serialize it to a struct when we need it on the host side.

+// Interfaces
+// ----------
+// Enumerates interfaces as (api_name, interface_name, interface_struct).
+//
+// The api_name corresponds to the class in the list above for the object
+// that implements the API. Some things may be special and aren't implemented
+// by any specific API object, and we use "NoAPIName" for those. Implementors
+// of these macros should handle this case. There can be more than one line
+// referring to the same api_name (typically different versions of the
+// same interface).
+//
+// The interface_name is the string that corresponds to the interface.
+//
+// The interface_struct is the typename of the struct corresponding to the
+// interface string.
