+Cobbler external inventory script
+=================================
+
+Ansible has a feature where instead of reading from /etc/ansible/hosts
+as a text file, it can query external programs to obtain the list
+of hosts, groups the hosts are in, and even variables to assign to each host.
+
+To use this, copy this file over /etc/ansible/hosts and chmod +x the file.
+This, more or less, allows you to keep one central database containing
+info about all of your managed instances.
+
+This script is an example of sourcing that data from Cobbler
+(http://cobbler.github.com). With cobbler each --mgmt-class in cobbler
+will correspond to a group in Ansible, and --ks-meta variables will be
+passed down for use in templates or even in argument lines.
+
+NOTE: The cobbler system names will not be used. Make sure a
+cobbler --dns-name is set for each cobbler system. If a system
+appears with two DNS names we do not add it twice because we don't want
+ansible talking to it twice. The first one found will be used. If no
+--dns-name is set the system will NOT be visible to ansible. We do
+not add cobbler system names because there is no requirement in cobbler
+that those correspond to addresses.
+
+See http://ansible.github.com/api.html for more info
+
+Tested with Cobbler 2.0.11.
