# description: This package is an implementation of "AFP over TCP"
#              and provides printer, file sharing, and routing 
#              services via legacy AppleTalk networking protocol.

# Netatalk :NETATALK_VERSION: daemons.
# If you use AppleTalk, Make sure not to start atalkd in the background:
# its data structures must have time to stablize before running the
# other processes.
