212 Usage: perl $0 --pid_dir @TMP@ --config @sysconfdir@/opensrf_core.xml --service opensrf.settings --action start
215 Actions include start, stop, restart, and start_all, stop_all, and restart_all
218 Specifies which OpenSRF service to control
221 OpenSRF configuration file
224 Directory where process-specific PID files are kept
227 Do not detach and run as a daemon process. Useful for debugging.
229 --settings-startup-pause
230 How long to give the opensrf.settings server to start up when running
231 in batch mode (start_all). The purpose is to give plenty of time for
232 the settings server to be up and active before any non-Perl services
