 Also note that the paths contained in `use` items are relative to the crate root.
 So, in the previous example, the `use` refers to `quux::foo::*`, and not simply to `foo::*`.
+This also means that top-level module declarations should be at the crate root if direct usage
+of the declared modules within `use` items is desired.  It is also possible to use `self` and `super`
+at the beginning of a `use` item to refer to the current and direct parent modules respectively.
+All rules regarding accessing declared modules in `use` declarations applies to both module declarations
