"""Collection of names of notable Python library modules.

Both standard library and third party modules are included. The
selection criteria for third party modules is somewhat arbitrary.

For packages we usually just include the top-level package name, but
sometimes some or all submodules are enumerated. In the latter case if
the top-level name is included we include all possible submodules
(this is an implementation limitation).

These are used to give more useful error messages when there is
no stub for a module.
