[pypy-dev] PYPYLOG

Hey. am confused about the debugging variable for PYPYLOG, have set its value, am trying to run the benchmark so that I can get some insights on how to use it in the future, however when I compile my file it doesn't show me the output file, do I need to set any other thing apart from the PYPYLOG environment variable, Which commands ensures that have run pypy to ensure that debugging is enabled?, any assistance is highly appreciated.
