The 'import' statement in Pyrex works exactly the same way
as it does in Python, i.e. any directory to be used as a
package must have an __init__.py file, and top-level
package directories must be in sys.path or PYTHONPATH,
etc.

All this happens at run time, so the Pyrex compiler
knows nothing about it (as opposed to 'cimport', which
is done at compile time).
