# This script allows you to quickly change your bind9 configuration:
#     - define an internal domain and bind it to 127.0.0.1
#     - add SRV records to use this domain with your local XMPP server
#
# BE SURE TO BACKUP /etc/bind AND /var/cache/bind BEFORE USING THIS SCRIPT!
#
# Configuration files based on:
#     - http://www.madboa.com/geek/soho-bind
#     - http://wiki.xmpp.org/web/SRV_Records
#     - http://prosody.im/doc/dns
#
# For this to work, Prosody configuration must define the domain as a VirtualHost.
# It is also assumed that the Prosody "directory" option is set to "/var/cache/bind".
