+Run Python regression tests.
+
+If no arguments or options are provided, finds all files matching
+the pattern "test_*" in the Lib/test subdirectory and runs
+them in alphabetical order (but see -M and -u, below, for exceptions).
+
+For more rigorous testing, it is useful to use the following
+command line:
+
+python -E -Wd -m test [options] [test_name1 ...]
+"""
+
+EPILOG = """\
+Additional option details:
+
+-r randomizes test execution order. You can use --randseed=int to provide an
+int seed value for the randomizer; this is useful for reproducing troublesome
+test orders.
+
+-s On the first invocation of regrtest using -s, the first test file found
+or the first test file given on the command line is run, and the name of
+the next test is recorded in a file named pynexttest. If run from the
+Python build directory, pynexttest is located in the 'build' subdirectory,
+otherwise it is located in tempfile.gettempdir(). On subsequent runs,
+the test in pynexttest is run, and the next test is written to pynexttest.
+When the last test has been run, pynexttest is deleted. In this way it
+is possible to single step through the test files. This is useful when
+doing memory analysis on the Python interpreter, which process tends to
+consume too many resources to run the full regression test non-stop.
+
+-S is used to continue running tests after an aborted run. It will
+maintain the order a standard run (ie, this assumes -r is not used).
+This is useful after the tests have prematurely stopped for some external
+reason and you want to start running from where you left off rather
+than starting from the beginning.
+
+-f reads the names of tests from the file given as f's argument, one
+or more test names per line. Whitespace is ignored. Blank lines and
+lines beginning with '#' are ignored. This is especially useful for
+whittling down failures involving interactions among tests.
+
+-L causes the leaks(1) command to be run just before exit if it exists.
+leaks(1) is available on Mac OS X and presumably on some other
+FreeBSD-derived systems.
+
+-R runs each test several times and examines sys.gettotalrefcount() to
+see if the test appears to be leaking references. The argument should
+be of the form stab:run:fname where 'stab' is the number of times the
+test is run to let gettotalrefcount settle down, 'run' is the number
+of times further it is run and 'fname' is the name of the file the
+reports are written to. These parameters all have defaults (5, 4 and
+"reflog.txt" respectively), and the minimal invocation is '-R :'.
+
+-M runs tests that require an exorbitant amount of memory. These tests
+typically try to ascertain containers keep working when containing more than
+2 billion objects, which only works on 64-bit systems. There are also some
+tests that try to exhaust the address space of the process, which only makes
+sense on 32-bit systems with at least 2Gb of memory. The passed-in memlimit,
+which is a string in the form of '2.5Gb', determines howmuch memory the
+tests will limit themselves to (but they may go slightly over.) The number
+shouldn't be more memory than the machine has (including swap memory). You
+should also keep in mind that swap memory is generally much, much slower
+than RAM, and setting memlimit to all available RAM or higher will heavily
+tax the machine. On the other hand, it is no use running these tests with a
+limit of less than 2.5Gb, and many require more than 20Gb. Tests that expect
+to use more than memlimit memory will be skipped. The big-memory tests
+generally run very, very long.
+
+-u is used to specify which special resource intensive tests to run,
+such as those requiring large file support or network connectivity.
+The argument is a comma-separated list of words indicating the
+resources to test. Currently only the following are defined:
+
+ all - Enable all special resources.
+
+ none - Disable all special resources (this is the default).
+
+ audio - Tests that use the audio device. (There are known
+ cases of broken audio drivers that can crash Python or
+ even the Linux kernel.)
+
+ curses - Tests that use curses and will modify the terminal's
+ state and output modes.
+
+ largefile - It is okay to run some test that may create huge
+ files. These tests can take a long time and may
+ consume >2GB of disk space temporarily.
+
+ network - It is okay to run tests that use external network
+ resource, e.g. testing SSL support for sockets.
+
+ decimal - Test the decimal module against a large suite that
+ verifies compliance with standards.
+
+ cpu - Used for certain CPU-heavy tests.
+
+ subprocess Run all tests for the subprocess module.
+
+ urlfetch - It is okay to download files required on testing.
+
+ gui - Run tests that require a running GUI.
+
+ tzdata - Run tests that require timezone data.
+
+To enable all resources except one, use '-uall,-<resource>'. For
+example, to run all the tests except for the gui tests, give the
+option '-uall,-gui'.
