+# Created by JvdZ
+
+Script that sends the captured mqtt records again to a server recorded in HA_Discovery_mqtt.log in dezelfde directory.
+
+usage:
+bash mqtt_ad_send.sh [-h hostname/ip] [-p port] [-s searchstring] [-i inputfile]
+   -h Hostname or Ipaddres of MQTT deamon. default is 127.0.0.1
+   -p port for the MQTT deamon. default is 1883
+   -u Userid for MQTT deamon
+   -P Password for MQTT deamon
+   -s only send MQTT messages that contain this string in the TOPIC or PAYLOAD. default is all messages
+   -i inputfile. default is mqtt_ad_record_all.log
+   -r override retain (y/n). defaults to the retain flag in the record
+   -d When Dry-run when switch is provided, no MQTT messages will be send, just the logging.
+
+example:
+   ALL records     :  bash mqtt_ad_send.sh
+   Selected records:  bash mqtt_ad_send.sh PARTIAL_DEVICE_NAME
