#  6May2015 AT Revised to be less Red Hat specific
#              Added status option. Seems to manage PID file
#              and process status correctly.
#  2Nov2012 EL Add LSB header, needed to start at boot.
#              Also needs: update-rc.d podriver-sph defaults
# 26Oct2012 Eric Lee Change path to driver.
#                    For Debian systems, posdriver-sph-debian may be better.
