ANNOUNCING:

                pybench -- The Python Benchmark Suite
                            Version 1.0.0

        Extendable suite of of low-level benchmarks for measuring
              the performance of the Python implementation 
                      (interpreter, compiler or VM).

________________________________________________________________________

WHAT IS IT ?:

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.

There's currently no documentation and no distutils support in 
pybench; that'll go into one of the next releases. For now,
please read the source code. 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. Here's some sample output:
