-/// \brief A ASTContext-independent way to refer to declarations.
-///
-/// Entity is basically the link for declarations that are semantically the same
-/// in multiple ASTContexts. A client will convert a Decl into an Entity and
-/// later use that Entity to find the "same" Decl into another ASTContext.
-/// Declarations that are semantically the same and visible across translation
-/// units will be associated with the same Entity.
-///
-/// An Entity may also refer to declarations that cannot be visible across
-/// translation units, e.g. static functions with the same name in multiple
-/// translation units will be associated with different Entities.
-///
-/// Entities can be checked for equality but note that the same Program object
-/// should be used when getting Entities.
-///
