-You can use `parrsb_default_options` struct instance to pass default options
-to `parrsb_part_mesh` routine. All of these options can be controlled at runtime
-by setting up the relevant environment variable (named as `PARRSB_<OPT_NAME>`)
-to the corresponding value as well. Enviornment variable values will override
-what is passed to `parrsb_part_mesh` routine.
