-# procd API:
-#
-# procd_open_service(name, [script]):
-# Initialize a new procd command message containing a service with one or more instances
-#
-# procd_close_service()
-# Send the command message for the service
-#
-# procd_open_instance([name]):
-# Add an instance to the service described by the previous procd_open_service call
-#
-# procd_set_param(type, [value...])
-# Available types:
-# command: command line (array).
-# env: environment variable (passed to the process)
-# data: arbitrary name/value pairs for detecting config changes (table)
-# file: configuration files (array)
-# netdev: bound network device (detects ifindex changes)
-#
-# No space separation is done for arrays/tables - use one function argument per command line argument
-#
-# procd_close_instance():
-# Complete the instance being prepared
-#
-# procd_kill(service, [instance]):
-# Kill a service instance (or all instances)
-#
