"""
Zabbix Server external inventory script.
========================================
Returns hosts and hostgroups from Zabbix Server.
If you want to run with --limit against a host group with space in the
name, use asterisk. For example --limit="Linux*servers".
Configuration is read from `zabbix.ini`.
Tested with Zabbix Server 2.0.6, 3.2.3 and 3.4.
