# ATTENTION:
#
# This skript works only if the following variable is kept in sync
# with a explicit configuration of the pidfile (sympa.conf),
# bounced_pidfile and archived_pidfile (wwsympa.conf) parameters!

# It should be quite generic and work on most UNIX-Systems. Esspecially
# it's a vailid HPUX 10.x/11.x startup skript.
#
# Arguments: start, stop, verify_up, verify_down, restart
#
# Return values (start and verify_up/stop verify_down):
# 0: Success (all are up/all are down)
# 1: Failure (including partial)
# 2: Skipped
