# Program: syslog-ng init script
#
# Description:
#
#  This is an init script for syslog-ng on the HP-UX platform.
#
#  To start the service, we check if the daemon program is executable.
#  Accordingly, the preferred way to disable the service PERMANENTLY
#  is to rename the binary or remove execute permissions.
#  Ideally, you would remove the software from your system entirely.
#
#  The lowest PID of a running instance of the executable is logged to a
#  file. This PID is used for killing the daemon. This is a best guess of
#  course, it is much better to use built-in shutdown functions if the
#  daemon has those.
#
#
# Platforms (tested): HP-UX (B.10.20)
