+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 just let the benchmark suite do it's thing and
+'pybench.py -f <file>' to have it store the results in a file too.
+
+This is the current output of pybench.py --help:
+
+Synopsis:
+ pybench.py [option] files...
+
+Options and default settings:
+  -n arg           number of rounds (10)
+  -f arg           save benchmark to file arg ()
+  -c arg           compare benchmark with the one in file arg ()
+  -s arg           show benchmark in file arg, then exit ()
+  -S               show statistics of benchmarks (0)
+  -w arg           set warp factor to arg (20)
+  -d               hide noise in compares (0)
+  --no-gc          disable garbage collection (0)
+  -v               generate verbose output
+  -h               show this help text
+  --help           show this help text
+  --debug          enable debugging
+  --copyright      show copyright
+  --examples       show examples of usage
+
+Version:
+ 1.3
+
+The normal operation is to run the suite and display the
+results. Use -f to save them for later reuse or comparisms.
+
+Examples:
+
+python1.5 pybench.py -w 100 -f p15
+python1.4 pybench.py -w 100 -f p14
+python pybench.py -s p15 -c p14

+
+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
+    # 20-50 seconds.
+    rounds = 100000
+
+    def test(self):
+
+	""" Run the test.
+
+	    The test needs to run self.rounds executing
+	    self.operations number of operations each.
+
+        """
+        # Init the test
+        a = 1
+
+        # Run test rounds
+	#
+        # NOTE: Use xrange() for all test loops unless you want to face
+	# a 20MB process !
+	#
+        for i in xrange(self.rounds):
+
+            # Repeat the operations per round to raise the run-time
+            # per operation significantly above the noise level of the
+            # for-loop overhead. 
+
+	    # Execute 20 operations (a += 1):
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+            a += 1
+
+    def calibrate(self):
+
+	""" Calibrate the test.
+
+	    This method should execute everything that is needed to
+	    setup and run the test - except for the actual operations
+	    that you intend to measure. pybench uses this method to
+            measure the test implementation overhead.
+
+        """
+        # Init the test
+        a = 1
+
+        # Run test rounds (without actually doing any operation)
+        for i in xrange(self.rounds):
+
+	    # Skip the actual execution of the operations, since we
+	    # only want to measure the test's administration overhead.
+            pass
+
+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.
+
+
