# Note: an upgrade prevention check has been added to the %pre section to ensure that
# this RPM cannot be upgraded. Upgrading this RPM will completely corrupt all of the CAVE
# rcp configuration information. So, a completely re-installation of this RPM and subsequently
# all of CAVE is required whenever an updated version of this RPM is released.
