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