11 Unit tests for the NLTK modules. These tests are intented to ensure
12 that changes that we make to NLTK's code don't accidentally introduce
13 bugs.
14
15 Each module in this package tests a specific aspect of NLTK. Modules
16 are typically named for the module or class that they test (e.g.,
17 L{nltk_lite.test.tree} performs tests on the L{nltk_lite.parse.tree}
18 module).
19
20 Use doctest_driver.py to run the tests:
21
22 doctest_driver.py --help
23
24 NB. Popular options for NLTK documentation are:
25
26 --ellipsis --normalize_whitespace
