# Narrow the scope of ownership/permissions.
# Security plan:
# * ZUID is the superuser for all zope instances.
# * ZGID is for a single instance's administration.
# * Other's should not have any access to ${ZSERVDIR},
#   because they can work through the Zope web interface.
#   This should protect our code/data better.

# Parameters:
#  $1 = instance directory
#  $2 = group

	# zope instances will be able to read everything.
