+PYBENCH - A Python Benchmark Suite
+________________________________________________________________________
+
+     Extendable suite of of low-level benchmarks for measuring
+          the performance of the Python implementation 
+                 (interpreter, compiler or VM).
+
+pybench is a collection of tests that provides a standardized way to
+measure the performance of Python implementations. It takes a very
+close look at different aspects of Python programs and let's you
+decide which factors are more important to you than others, rather
+than wrapping everything up in one number, like the other performance
+tests do (e.g. pystone which is included in the Python Standard
+Library).
+
+pybench has been used in the past by several Python developers to
+track down performance bottlenecks or to demonstrate the impact of
+optimizations and new features in Python.
+
+The command line interface for pybench is the file pybench.py. Run
+this script with option '--help' to get a listing of the possible
+options. Without options, pybench will simply execute the benchmark
+and then print out a report to stdout.
+
+
+Micro-Manual
+------------
+
+Run 'pybench.py -h' to see the help screen.  Run 'pybench.py' to run
+the benchmark suite using default settings and 'pybench.py -f <file>'
+to have it store the results in a file too.
+
+It is usually a good idea to run pybench.py multiple times to see
+whether the environment, timers and benchmark run-times are suitable
+for doing benchmark tests. 
+
+You can use the comparison feature of pybench.py ('pybench.py -c
+<file>') to check how well the system behaves in comparison to a
+reference run. 
+
+If the differences are well below 10% for each test, then you have a
+system that is good for doing benchmark testings.  Of you get random
+differences of more than 10% or significant differences between the
+values for minimum and average time, then you likely have some
+background processes running which cause the readings to become
+inconsistent. Examples include: web-browsers, email clients, RSS
+readers, music players, backup programs, etc.
+
+If you are only interested in a few tests of the whole suite, you can
+use the filtering option, e.g. 'pybench.py -t string' will only
+run/show the tests that have 'string' in their name.
+
+This is the current output of pybench.py --help:

+Writing New Tests
+________________________________________________________________________
+
+pybench tests are simple modules defining one or more pybench.Test
+subclasses.
+
+Writing a test essentially boils down to providing two methods:
+.test() which runs .rounds number of .operations test operations each
+and .calibrate() which does the same except that it doesn't actually
+execute the operations.
+
+
+Here's an example:
+------------------
+
+from pybench import Test
+
+class IntegerCounting(Test):
+
+    # Version number of the test as float (x.yy); this is important
+    # for comparisons of benchmark runs - tests with unequal version
+    # number will not get compared.
+    version = 1.0
+    
+    # The number of abstract operations done in each round of the
+    # test. An operation is the basic unit of what you want to
+    # measure. The benchmark will output the amount of run-time per
+    # operation. Note that in order to raise the measured timings
+    # significantly above noise level, it is often required to repeat
+    # sets of operations more than once per test round. The measured
+    # overhead per test round should be less than 1 second.
+    operations = 20
+
+    # Number of rounds to execute per test run. This should be
+    # adjusted to a figure that results in a test run-time of between
+    # 1-2 seconds (at warp 1).
+    rounds = 100000
+
+    def test(self):
+
+	""" Run the test.
+
+	    The test needs to run self.rounds executing
+	    self.operations number of operations each.

+
+Registering a new test module
+-----------------------------
+
+To register a test module with pybench, the classes need to be
+imported into the pybench.Setup module. pybench will then scan all the
+symbols defined in that module for subclasses of pybench.Test and
+automatically add them to the benchmark suite.
+
+
+Breaking Comparability
+----------------------
+
+If a change is made to any individual test that means it is no
+longer strictly comparable with previous runs, the '.version' class
+variable should be updated. Therefafter, comparisons with previous
+versions of the test will list as "n/a" to reflect the change.
+
+
+Version History
+---------------
+
+  2.0: rewrote parts of pybench which resulted in more repeatable
+       timings:
+        - made timer a parameter
+        - changed the platform default timer to use high-resolution
+          timers rather than process timers (which have a much lower
+          resolution)
+        - added option to select timer
+        - added process time timer (using systimes.py)
+        - changed to use min() as timing estimator (average
+          is still taken as well to provide an idea of the difference)
+        - garbage collection is turned off per default
+        - sys check interval is set to the highest possible value
+        - calibration is now a separate step and done using
+          a different strategy that allows measuring the test
+          overhead more accurately
+        - modified the tests to each give a run-time of between
+          100-200ms using warp 10
+        - changed default warp factor to 10 (from 20)
+        - compared results with timeit.py and confirmed measurements
+        - bumped all test versions to 2.0
+        - updated platform.py to the latest version
+        - changed the output format a bit to make it look
+          nicer
+        - refactored the APIs somewhat
+  1.3+: Steve Holden added the NewInstances test and the filtering 
+       option during the NeedForSpeed sprint; this also triggered a long 
+       discussion on how to improve benchmark timing and finally
+       resulted in the release of 2.0
+  1.3: initial checkin into the Python SVN repository

+#    History:
+#
+#    <see CVS and SVN checkin messages for history>
+#
+#    1.0.3 - added normalization of Windows system name
+#    1.0.2 - added more Windows support
+#    1.0.1 - reformatted to make doc.py happy
+#    1.0.0 - reformatted a bit and checked into Python CVS
+#    0.8.0 - added sys.version parser and various new access
+#            APIs (python_version(), python_compiler(), etc.)
+#    0.7.2 - fixed architecture() to use sizeof(pointer) where available
+#    0.7.1 - added support for Caldera OpenLinux
+#    0.7.0 - some fixes for WinCE; untabified the source file
+#    0.6.2 - support for OpenVMS - requires version 1.5.2-V006 or higher and
+#            vms_lib.getsyi() configured
+#    0.6.1 - added code to prevent 'uname -p' on platforms which are
+#            known not to support it
+#    0.6.0 - fixed win32_ver() to hopefully work on Win95,98,NT and Win2k;
+#            did some cleanup of the interfaces - some APIs have changed
+#    0.5.5 - fixed another type in the MacOS code... should have
+#            used more coffee today ;-)
+#    0.5.4 - fixed a few typos in the MacOS code
+#    0.5.3 - added experimental MacOS support; added better popen()
+#            workarounds in _syscmd_ver() -- still not 100% elegant
+#            though
+#    0.5.2 - fixed uname() to return '' instead of 'unknown' in all
+#            return values (the system uname command tends to return
+#            'unknown' instead of just leaving the field emtpy)
+#    0.5.1 - included code for slackware dist; added exception handlers
+#            to cover up situations where platforms don't have os.popen
+#            (e.g. Mac) or fail on socket.gethostname(); fixed libc
+#            detection RE
+#    0.5.0 - changed the API names referring to system commands to *syscmd*;
+#            added java_ver(); made syscmd_ver() a private
+#            API (was system_ver() in previous versions) -- use uname()
+#            instead; extended the win32_ver() to also return processor
+#            type information
+#    0.4.0 - added win32_ver() and modified the platform() output for WinXX
+#    0.3.4 - fixed a bug in _follow_symlinks()
+#    0.3.3 - fixed popen() and "file" command invokation bugs
+#    0.3.2 - added architecture() API and support for it in platform()
+#    0.3.1 - fixed syscmd_ver() RE to support Windows NT
+#    0.3.0 - added system alias support
+#    0.2.3 - removed 'wince' again... oh well.
+#    0.2.2 - added 'wince' to syscmd_ver() supported platforms
+#    0.2.1 - added cache logic and changed the platform string format
+#    0.2.0 - changed the API to use functions instead of module globals
+#            since some action take too long to be run on module import
+#    0.1.0 - first release

+        clock()-timing only gives rather inaccurate values (on Linux,
+        for example, it is accurate to a few hundreths of a
+        second). If you don't want to wait that long, use a warp
+        factor larger than 1.
+
+        It is also important to set the .operations variable to a
+        value representing the number of "virtual operations" done per
+        call of .run().
+
+        If you change a test in some way, don't forget to increase
+        it's version number.

+
+""" systimes() user and system timer implementations for use by
+    pybench.
+
+    This module implements various different strategies for measuring
+    performance timings. It tries to choose the best available method
+    based on the platforma and available tools.
+
+    On Windows, it is recommended to have the Mark Hammond win32
+    package installed. Alternatively, the Thomas Heller ctypes
+    packages can also be used.
+
+    On Unix systems, the standard resource module provides the highest
+    resolution timings. Unfortunately, it is not available on all Unix
+    platforms.
+
+    If no supported timing methods based on process time can be found,
+    the module reverts to the highest resolution wall-clock timer
+    instead. The system time part will then always be 0.0.
+
+    The module exports one public API:
+
+    def systimes():
+
+        Return the current timer values for measuring user and system
+        time as tuple of seconds (user_time, system_time).
