# This init-script tries to be LSB conform but platform independent.
# 
# Therefore check the following two variables to fit to your requests:
# HAVP_BIN HAVP_CONFIG PIDFILE
# Any configuration of HAVP is done in havp.config
# Type havp --help for help and read havp.config you should have received.

HAVP_BIN=/usr/local/sbin/havp
HAVP_CONFIG=/etc/havp/havp.config
PIDFILE=/var/run/havp/havp.pid

# Return values acc. to LSB for all commands but status:
# 1       generic or unspecified error (current practice)
# 2       invalid or excess argument(s)
# 3       unimplemented feature (for example, "reload")
# 4       user had insufficient privilege
# 5       program is not installed
# 6       program is not configured
# 7       program is not running
# 8-99    reserved for future LSB use
# 100-149 reserved for distribution use
# 150-199 reserved for application use
# 200-254 reserved
# Note that starting an already running service, stopping
# or restarting a not-running service as well as the restart
# with force-reload (in case signaling is not supported) are
# considered a success.
