+The purpose of the :mod:`importlib` package is two-fold. One is to provide the
 implementation of the :keyword:`import` statement (and thus, by extension, the
 :func:`__import__` function) in Python source code. This provides an
 implementation of :keyword:`import` which is portable to any Python
-interpreter. This also provides a reference implementation which is easier to
+interpreter. This also provides an implementation which is easier to
 comprehend than one implemented in a programming language other than Python.
 
 Two, the components to implement :keyword:`import` are exposed in this
 package, making it easier for users to create their own custom objects (known
 generically as an :term:`importer`) to participate in the import process.
-Details on custom importers can be found in :pep:`302`.
