# iTunes Shared Library Permissions Fixer
#
# This periodic script will fix the permissions of a directory tree to
# allow multiple users to shared read and write access that tree. This
# is most useful for sharing an iTunes music library between multiple
# users on a single Mac.
#
# Install this script with permissions 755 into /etc/periodic/daily
# and it will run once a day as long as your Mac is running at night.
#
# If your mac if off at night (putting your powerbook to sleep for example)
# you should get the anacron package from:
# http://www.alastairs-place.net/anacron.html

# and write accessible for members of SHAREGRP. Be sure to include the
