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