+libvirt 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.
