A Python namespace control and lazy-import mechanism
Description
With apipkg you can control the exported namespace of a Python package and greatly reduce the number
of imports for your users. It is a small pure Python module that works on CPython 2.7 and 3.4+,
Jython and PyPy. It cooperates well with Python's help() system, custom importers (PEP302) and
common command-line completion tools.
