-"""Resolve interface dependencies, producing a merged IdlDefinitions object.

-This library computes interface dependencies (partial interfaces and
-implements), reads the dependency files, and merges them to the IdlDefinitions
-for the main IDL file, producing an IdlDefinitions object representing the
-entire interface.
-
-It also checks whether a file should have bindings generated, or whether
-instead it is just a dependency.
