+== Component Declaration Hierarchy ==
+
+Module Foo declares Component SomeCompent.
+Module Bar wants to use Component SomeCompent.
+Module Bar cannot also declare SomeComponent.
+
+Module Bar must import Module Foo.
+OR SomeComp is declared in a new shared module that is imported
+by both Foo and Bar.
