**Usage**
This class is able to read and parse the content of zone file by doing:
>>> import ldns
>>> zone = ldns.ldns_zone.new_frm_fp(open(\"zone.txt\",\"r\"), None, 0, ldns.LDNS_RR_CLASS_IN)
>>> print zone.soa()
example. 600 IN SOA example. admin.example. 2008022501 28800 7200 604800 18000
>>> print zone.rrs()
example. 600 IN MX 10 mail.example.
example. 600 IN NS ns1.example.
example. 600 IN NS ns2.example.
example. 600 IN A 192.168.1.1
The ``zone.txt`` file contains the following records::
$ORIGIN example.
$TTL 600
example. IN SOA example. admin.example. (
2008022501 ; serial
28800 ; refresh (8 hours)
7200 ; retry (2 hours)
604800 ; expire (1 week)
18000 ; minimum (5 hours)
)
