"""Starter script for all nova services.

|
|
This script attempts to start all the nova services in one process. Each
|
|
service is started in its own greenthread. Please note that exceptions and
|
|
sys.exit() on the starting of a service are logged and the script will
|
|
continue attempting to launch the rest of the services.
