# ebuilds to build extensions for python2.1.

# * ZUID is the superuser for all zope instances.

# * 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.
#
# UPDATE: ${ZSERVDIR} is a lib directory and should be world readable
# like e.g /usr/lib/python we do not store any user data there,
# currently removed all custom permission stuff, for ${ZSERVDIR}

#  $1 = instance directory
