'usr/bin/foobar.py' this method should probably be called with
program_name='foobar' However, this is just a convention, you can
pass in any string you want, and it will be used as part of the
log filename. If you don't pass in anything, the default behavior
is as described in the example. In python standard logging mode,
the program_name will be prepended with py_ if it is the program_name
