# afpsync: updates .AppleDouble components of files on shared volumes

# this must be used if any files are copied to the shared volume via
# non-AFP methods (directly, via Samba, etc).

# usage:
# afpsync [-v] [shared volume path]
#
# -v will silently create a .volinfo file if none exists.
# If a path is specified, only that volume is synced; otherwise, all
# all paths in /media which appear in
# /usr/local/etc/netatalk/AppleVolumes.default are synced.
