>>> z = easyzone.zone_from_file('example.com', '/var/namedb/example.com')
>>> z.domain
'example.com.'
>>> z.root.soa.serial
2007012902L
>>> z.root.records('NS').items
['ns1.example.com.', 'ns2.example.com.']
>>> z.root.records('MX').items
[(10, 'mail.example.com.'), (20, 'mail2.example.com.')]
>>> z.names['foo.example.com.'].records('A').items
['10.0.0.1']

>>> ns = z.root.records('NS')
>>> ns.add('ns3.example.com.')
>>> ns.items
['ns1.example.com.', 'ns2.example.com.', 'ns3.example.com.']
>>> ns.delete('ns2.example.com')
>>> ns.items
['ns1.example.com.', 'ns3.example.com.']

>>> z.save(autoserial=True)

ZoneCheck:

>>> from easyzone.zone_check import ZoneCheck
>>> c = ZoneCheck()
>>> c.isValid('example.com', '/var/named/zones/example.com')
True
>>> c.isValid('foo.com', '/var/named/zones/example.com')
False
>>> c.error
'Bad syntax'
>>>
>>> c = ZoneCheck(checkzone='/usr/sbin/named-checkzone')
>>> c.isValid('example.com', '/var/named/zones/example.com')
True
>>>

ZoneReload:

>>> from easyzone.zone_reload import ZoneReload
>>> r = ZoneReload()
>>> r.reload('example.com')
zone reload up-to-date
>>> r.reload('foo.com')
rndc: 'reload' failed: not found
Traceback (most recent call last):
