# This script sets special permissions on files and directories needed

#
# Lines starting with "# PERMS: " are data read by this script that
# name the files and directories required to have special permissions
# in order for this package to function correctly.

# For each PERMS entry, if the file path is relative, then it is taken to
# be relative to ${PKG_PREFIX}.
