# Therefore check the following two variables to fit to your requests:

# HAVP_BIN HAVP_CONFIG PIDFILE
12 
# Any configuration of HAVP is done in havp.config

# Type havp --help for help and read havp.config you should have received.

# 3       unimplemented feature (for example, "reload")

# 4       user had insufficient privilege

# Note that starting an already running service, stopping
32 
# or restarting a not-running service as well as the restart
33 
# with force-reload (in case signaling is not supported) are
34
