+# 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)
