Under Unix operating systems, the default configuration file is /etc/pse/pse.conf. Under Windows, the default location is in etc/pse/pse.conf in the directory Python was installed in.
You can change the configuration file that is being used by PSE using
PythonOption directive. This lets you keep your
configuration someplace else, such as under version control.
You can use this directive to have a different configuration for each PSE instance (see section 3.1.5).
PythonOption PSEConf /path/to/your/pse.conf
For more information on the configuration file and what it does, see section 3.2.
