204 Usage: perl $0 --pid_dir /var/run/opensrf --config /etc/opensrf/opensrf_core.xml --service opensrf.settings --action start
207 Actions include start, stop, restart, and start_all, stop_all, and restart_all
210 Specifies which OpenSRF service to control
213 OpenSRF configuration file
216 Directory where process-specific PID files are kept
219 Do not detach and run as a daemon process. Useful for debugging.
221 --settings-startup-pause
222 How long to give the opensrf.settings server to start up when running
223 in batch mode (start_all). The purpose is to give plenty of time for
224 the settings server to be up and active before any non-Perl services
