  --version 	Display the version of the script
  --help    	Display these usage notes

The most commonly used ${SCRIPT} commands are:
  
  list                                 	list the publisher codes in config server database
  add [<AU_PUB_ID>] [<PUBLISHER_NAME>] 	add a publisher code for a new content source
  remove [<AU_PUB_ID>]                 	remove a publisher code
  
Exit codes:
0 = success (successful operation and expected result)
1-254 = error in executing command
255 = command not supported
