+"""Test suite for 2to3's parser and grammar files.
+
+This is the place to add tests for changes to 2to3's grammar, such as those
+merging the grammars for Python 2 and 3. In addition to specific tests for
+parts of the grammar we've changed, we also make sure we can parse the
+test_grammar.py files from both Python 2 and Python 3.
