      1 """Run the Python regression test using the compiler
      2 
      3 This test runs the standard Python test suite using bytecode generated
      4 by this compiler instead of by the builtin compiler.
      5 
      6 The regression test is run with the interpreter in verbose mode so
      7 that import problems can be observed easily.
