+"""Test suite for distutils.
+
+This test suite consists of a collection of test modules in the
+distutils.tests package.  Each test module has a name starting with
+'test' and contains a function test_suite().  The function is expected
+to return an initialized unittest.TestSuite instance.
+
+Tests for the command classes in the distutils.command package are
+included in distutils.tests as well, instead of using a separate
+distutils.command.tests package, since command identification is done
+by import rather than matching pre-defined names.
