"""
Unit tests for the NLTK modules.  These tests are intended to ensure
that changes that we make to NLTK's code don't accidentally introduce
bugs.

Use doctest_driver.py to run the tests::

  doctest_driver.py --help

NB. Popular options for NLTK documentation are::

  --ellipsis --normalize_whitespace
