"""New import scheme with package support.
+Quick Reference
+---------------
+
+- To enable package support, execute "import ni" before importing any
+ packages. Importing this module automatically installs the relevant
+ import hooks.
+
+- To create a package named spam containing sub-modules ham, bacon and
+ eggs, create a directory spam somewhere on Python's module search
+ path (i.e. spam's parent directory must be one of the directories in
+ sys.path or $PYTHONPATH); then create files ham.py, bacon.py and
+ eggs.py inside spam.
+
+- To import module ham from package spam and use function hamneggs()
+ from that module, you can either do
+
+ import spam.ham # *not* "import spam" !!!
+ spam.ham.hamneggs()
+
+ or
+
+ from spam import ham
+ ham.hamneggs()
+
+ or
+
+ from spam.ham import hamneggs
+ hamneggs()
+
+- Importing just "spam" does not do what you expect: it creates an
+ empty package named spam if one does not already exist, but it does
+ not import spam's submodules. The only submodule that is guaranteed
+ to be imported is spam.__init__, if it exists. Note that
+ spam.__init__ is a submodule of package spam. It can reference to
+ spam's namespace via the '__.' prefix, for instance
+
+ __.spam_inited = 1 # Set a package-level variable
+
+
+
+Theory of Operation
+-------------------
+
A Package is a module that can contain other modules. Packages can be
nested. Package introduce dotted names for modules, like P.Q.M, which
could correspond to a file P/Q/M.py found somewhere on sys.path. It
