 importlib: Importing Modules
 ------------------------------
 
-XXX write this
+Python 3.1 includes the :mod:`importlib` package, a re-implementation
+of the logic underlying Python's :keyword:`import` statement.
+:mod:`importlib` is useful for implementors of Python interpreters and
+to user who wish to write new importers that can participate in the
+import process.  Python 2.7 doesn't contain the complete
+:mod:`importlib` package, but instead has a tiny subset that contains
+a single function, :func:`import_module`.
+
+``import_module(*name*, *package*=None)`` imports a module.  *name* is
+a string containing the module or package's name.  It's possible to do
+relative imports by providing a string that begins with a ``.``
+character, such as ``..utils.errors``.  For relative imports, the
+*package* argument must be provided and is the name of the package that
+will be used as the anchor for
+the relative import.  :func:`import_module` both inserts the imported
+module into ``sys.modules`` and returns the module object.
+
+Here are some examples::
+
+    >>> from importlib import import_module
+    >>> anydbm = import_module('anydbm')  # Standard absolute import
+    >>> anydbm
+    <module 'anydbm' from '/p/python/Lib/anydbm.py'>
+    >>> # Relative import
+    >>> sysconfig = import_module('..sysconfig', 'distutils.command')
+    >>> sysconfig
+    <module 'distutils.sysconfig' from '/p/python/Lib/distutils/sysconfig.pyc'>
+
+:mod:`importlib` was implemented by Brett Cannon and introduced in
+Python 3.1.
