=head1 METHODS

=head2 new(uid,token)

Initialize the object. You should be able to get your UID and token from DNSbed.com

=head2 addZone(zonename)

The argument is the valid zone name, i.e, google.com, but not www.google.com

For the result of this method and all the methods below, just Data::Dumper it.

    use Data::Dumper;
    my $res = $dnsbed->addZone("example.com");
    print Dumper $res;

=head2 listZones()

    use Data::Dumper;
    my $res = $dnsbed->listZones;
    print Dumper $res;

=head2 delZone(zid)

The only argument is a valid zone ID.

=head2 addRecord(zid,%rr_hash)

The first argument is zid, which must be provided.

The keys in %rr_hash must have:

rname: the record's name, i.e, www (but not www.example.com)

rtype: the record's type, which can be one of these: A, CNAME, AAAA, MX, NS, TXT

rvalue: the record's value, it could be an IP address or a hostname, based on the type

ttl: the record's TTL, it's a number, i.e, 600 means 600 seconds

mxnum: if the record's type is MX, this means MX host's priority, otherwise it's meaningless

=head2 modifyRecord(zid,%rr_hash)

The first argument is zid, which must be provided.

The keys in %rr_hash must have:

rid: the record's ID with the values you want to modify

rname, rtype, rvalue, ttl, mxnum: the new values provided by you

Notice: after executing this method, the old RID will be lost, with the new record you get a new RID, not the before one.

=head2 delRecord(zid,%rr_hash)

The first argument is zid, which must be provided.

The keys in %rr_hash must have:

rid: the record's ID with the values you want to delete

=head2 listRecords(zid,%optional_rr_hash)

The first argument is zid, which must be provided.

If you don't provide the second argument, it returns all the records for this zone ID.

%optional_rr_hash could have one of these two keys:

rid: if provided, it returns only one record with this rid

rids: it could be, i.e, "1,2,3,4", then returns the records with rid 1,2,3 and 4

=head2 searchRecords(zid,%kw_hash)

The first argument is zid, which must be provided.

The keys in %kw_hash must have:

keyword: the keyword you want to search with

It returns the records whose rname or rvalue have the keyword included.
