# unpack_engine
#
# This file contains install information and procedures
# specific to the vision engine

# These shell variables specify which engine will be
# installed.  Set UNPACK_SUN to 1 if you want the
# Sun version installed, UNPACK_AIX to 1 if you want
# the IBM version installed, and/or UNPACK_HP to 1 if
# you want the HP version installed.  You can have any
# or all of these set to 1 or 0, but these values need
# to be consistent with UNPACK_ENGINE variable in 
# unpack_vision.
