31.2. "importlib" — Convenience wrappers for "__import__()"
***********************************************************

New in version 2.7.

This module is a minor subset of what is available in the more full-
featured package of the same name from Python 3.1 that provides a
complete implementation of "import". What is here has been provided to
help ease in transitioning from 2.7 to 3.1.

importlib.import_module(name, package=None)

   Import a module. The *name* argument specifies what module to
   import in absolute or relative terms (e.g. either "pkg.mod" or
   "..mod"). If the name is specified in relative terms, then the
   *package* argument must be specified to the package which is to act
   as the anchor for resolving the package name (e.g.
   "import_module('..mod', 'pkg.subpkg')" will import "pkg.mod").  The
   specified module will be inserted into "sys.modules" and returned.
