old_contents: """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.
