A package with a namespace can be loaded and not attached or loaded and attached.

Use loadedNamespaces() to see what is loaded, and search() to see what is attached.

.Last.lib() gets called by detach() is called. .onUnload() is called by unloadNamespace(). I'm pretty sure you can have both .Last.lib and .onUnload in a package with a namespace.
