# This is the startup script for the replicator daemon which is part of
# the Perforce Defect Tracking Integration (P4DTI).  It is normally
# installed in the /etc/rc.d/init.d directory on Linux machines so
# that the daemon is automatically started and stopped by the system,
# and can be managed by the system administrator.
