# Fix ownership/permissions of the dconf.org account on the

# This rewrites the data directory on the web server to reset all file
# and directory permissions. It ensures everything is group writable
# and the sgid bit on directories is set, so that all users in the
# dconf.org group can update the website.

# This script must be run on the digitalmars.com server.
