+    object PyImport_ImportModule(char *name)
+    # Return value: New reference.
+    # This is a simplified interface to PyImport_ImportModuleEx()
+    # below, leaving the globals and locals arguments set to
+    # NULL. When the name argument contains a dot (when it specifies a
+    # submodule of a package), the fromlist argument is set to the
+    # list ['*'] so that the return value is the named module rather
+    # than the top-level package containing it as would otherwise be
+    # the case. (Unfortunately, this has an additional side effect
+    # when name in fact specifies a subpackage instead of a submodule:
+    # the submodules specified in the package's __all__ variable are
+    # loaded.) Return a new reference to the imported module, or NULL
+    # with an exception set on failure.
+
+    object PyImport_ImportModuleEx(char *name, object globals, object locals, object fromlist)

+    # Import a module. This is best described by referring to the
+    # built-in Python function __import__(), as the standard
+    # __import__() function calls this function directly.
+
+    # The return value is a new reference to the imported module or
+    # top-level package, or NULL with an exception set on failure
+    # (before Python 2.4, the module may still be created in this
+    # case). Like for __import__(), the return value when a submodule
+    # of a package was requested is normally the top-level package,
+    # unless a non-empty fromlist was given. Changed in version 2.4:
+    # failing imports remove incomplete module objects.
+
+    object PyImport_Import(object name)
+    # Return value: New reference.
+    # This is a higher-level interface that calls the current ``import
+    # hook function''. It invokes the __import__() function from the
+    # __builtins__ of the current globals. This means that the import
+    # is done using whatever import hooks are installed in the current
+    # environment, e.g. by rexec or ihooks.
+
+    object PyImport_ReloadModule(object m)
+    # Return value: New reference.
+    # Reload a module. This is best described by referring to the
+    # built-in Python function reload(), as the standard reload()
+    # function calls this function directly. Return a new reference to
+    # the reloaded module, or NULL with an exception set on failure
+    # (the module still exists in this case).
+
+    PyObject* PyImport_AddModule(char *name) except NULL
+    # Return value: Borrowed reference.
+    # Return the module object corresponding to a module name. The
+    # name argument may be of the form package.module. First check the
+    # modules dictionary if there's one there, and if not, create a
+    # new one and insert it in the modules dictionary. Return NULL
+    # with an exception set on failure. Note: This function does not
+    # load or import the module; if the module wasn't already loaded,
+    # you will get an empty module object. Use PyImport_ImportModule()
+    # or one of its variants to import a module. Package structures
+    # implied by a dotted name for name are not created if not already
+    # present.
+
+    object PyImport_ExecCodeModule(char *name, object co)
+    # Return value: New reference.
+    # Given a module name (possibly of the form package.module) and a
+    # code object read from a Python bytecode file or obtained from
+    # the built-in function compile(), load the module. Return a new
+    # reference to the module object, or NULL with an exception set if
+    # an error occurred. Name is removed from sys.modules in error
+    # cases, and even if name was already in sys.modules on entry to
+    # PyImport_ExecCodeModule(). Leaving incompletely initialized
+    # modules in sys.modules is dangerous, as imports of such modules
+    # have no way to know that the module object is an unknown (and
+    # probably damaged with respect to the module author's intents)
+    # state.
+    # This function will reload the module if it was already
+    # imported. See PyImport_ReloadModule() for the intended way to
+    # reload a module.
+    # If name points to a dotted name of the form package.module, any
+    # package structures not already created will still not be
+    # created.
+
+
+    long PyImport_GetMagicNumber()
+    # Return the magic number for Python bytecode files (a.k.a. .pyc
+    # and .pyo files). The magic number should be present in the first
+    # four bytes of the bytecode file, in little-endian byte order.
+
+    PyObject* PyImport_GetModuleDict() except NULL

+    # variable.
+
+
+    int PyImport_ImportFrozenModule(char *name) except -1
+    # Load a frozen module named name. Return 1 for success, 0 if the
+    # module is not found, and -1 with an exception set if the
+    # initialization failed. To access the imported module on a
+    # successful load, use PyImport_ImportModule(). (Note the misnomer
+    # -- this function would reload the module if it was already
+    # imported.)
+
+
+    int PyImport_ExtendInittab(_inittab *newtab) except -1
+    # Add a collection of modules to the table of built-in
+    # modules. The newtab array must end with a sentinel entry which
+    # contains NULL for the name field; failure to provide the
+    # sentinel value can result in a memory fault. Returns 0 on
+    # success or -1 if insufficient memory could be allocated to
+    # extend the internal table. In the event of failure, no modules
+    # are added to the internal table. This should be called before
+    # Py_Initialize().
