+# SYNOPSIS
+#
+#   AC_PROG_SWIG([major.minor.micro])
+#
+# DESCRIPTION
+#
+#   This macro searches for a SWIG installation on your system. If found you
+#   should call SWIG via $(SWIG). You can use the optional first argument to
+#   check if the version of the available SWIG is greater than or equal to
+#   the value of the argument. It should have the format: N[.N[.N]] (N is a
+#   number between 0 and 999. Only the first N is mandatory.)
+#
+#   If the version argument is given (e.g. 1.3.17), AC_PROG_SWIG checks that
+#   the swig package is this version number or higher.
+#
+#   In configure.in, use as:
+#
+#     AC_PROG_SWIG(1.3.17)
+#     SWIG_ENABLE_CXX
+#     SWIG_MULTI_MODULE_SUPPORT
+#     SWIG_PYTHON

 * aggressive negative caching for NSEC, NSEC3.
 * multiple queries per question, server exploration, server selection.
-* NSID support.
 * support TSIG on queries, for validating resolver deployment.
-* private TTL

  of responses over a time interval is collected, and each is validated.

+o NXDOMAIN and SOA serial numbers.
+  Unbound keeps TTL values for message formats, and thus rcodes, such
+  as NXDOMAIN.  Also it keeps the latest rrsets in the rrset cache.
+  So it will faithfully negative cache for the exact TTL as originally
+  specified for an NXDOMAIN message, but send a newer SOA record if
+  this has been found in the mean time.  In point, this could lead to a
+  negative cached NXDOMAIN reply with a SOA RR where the serial number
+  indicates a zone version where this domain is not any longer NXDOMAIN.
+  These situations become consistent once the original TTL expires.
+  If the domain is DNSSEC signed, by the way, then NSEC records are
+  updated more carefully.  If one of the NSEC records in an NXDOMAIN is
+  updated from another query, the NXDOMAIN is dropped from the cache,
+  and queried for again, so that its proof can be checked again.
+
+o SOA records in negative cached answers for DS queries.
+  The current unbound code uses a negative cache for queries for type DS.
+  This speeds up building chains of trust, and uses NSEC and NSEC3
+  (optout) information to speed up lookups.  When used internally,
+  the bare NSEC(3) information is sufficient, probably picked up from
+  a referral.  When answering to clients, a SOA record is needed for
+  the correct message format, a SOA record is picked from the cache
+  (and may not actually match the serial number of the SOA for which the
+  NSEC and NSEC3 records were obtained) if available otherwise network
+  queries are performed to get the data.
+
+o Parent and child with different nameserver information.
+  A misconfiguration that sometimes happens is where the parent and child
+  have different NS, glue information.  The child is authoritative, and
+  unbound will not trust information from the parent nameservers as the
+  final answer.  To help lookups, unbound will however use the parent-side
+  version of the glue as a last resort lookup.  This resolves lookups for
+  those misconfigured domains where the servers reported by the parent
+  are the only ones working, and servers reported by the child do not.

+	elif status != 0:
+		print "Resolve error:", unbound.ub_strerror(status)
+
+In contrast with C API, the source code is more compact while the performance of C implementation is preserved. 
+The main advantage is that you need not take care about the deallocation and allocation of context and result structures; pyUnbound module do it automatically for you. 
+
+If only domain name is given, the :meth:`unbound.ub_ctx.resolve` looks for A records in IN class.

+Reverse DNS lookup
+==============================
+
+Reverse DNS lookup involves determining the hostname associated with a given IP address.
+This example shows how reverse lookup can be done using unbound module.
+
+For the reverse DNS records, the special domain in-addr.arpa is reserved. 
+For example, a host name for the IP address 74.125.43.147 can be obtained by issuing a DNS query for the PTR record for address 147.43.125.74.in-addr.arpa.
+
+::
+
+	#!/usr/bin/python
+	import unbound
+	
+	ctx = unbound.ub_ctx()
+	ctx.resolvconf("/etc/resolv.conf")
+	
+	status, result = ctx.resolve(unbound.reverse("74.125.43.147") + ".in-addr.arpa.", unbound.RR_TYPE_PTR, unbound.RR_CLASS_IN)
+	if status == 0 and result.havedata:
+		print "Result.data:", result.data.domain_list
+	elif status != 0:
+		print "Resolve error:", unbound.ub_strerror(status)
+
+In order to simplify the python code, unbound module contains function which reverses the hostname components. 
+This function is defined as follows::

+Introduction
+===================================
+
+**Unbound**
+
+	`Unbound`_  is  an implementation of a DNS resolver, that performs caching and DNSSEC validation.
+	Together with unbound, the libunbound library is provided.
+	This library can be used to convert hostnames to ip addresses, and back, as well as obtain other information. 
+	Since the resolver allows to specify the class and type of a query (A record, NS, MX, ...), this library offers powerful resolving tool. 
+	The library also performs public-key validation of results with DNSSEC.
+	
+	.. _Unbound: http://www.unbound.net/documentation
+
+**pyUnbound**
+
+	The pyUnbound is an extension module for Python which provides an object-oriented interface to libunbound. 
+	It is the first Python module which offers thread-safe caching resolver.
+	
+	The interface was designed with the emphasis on the simplicity of use.
+	There are two main classes :class:`unbound.ub_ctx` (a validation and resolution context) and :class:`unbound.ub_result` which contains the validation and resolution results.
+	The objects are thread-safe, and a context can be used in non-threaded as well as threaded environment. 
+	Resolution can be performed blocking and non-blocking (i.e. asynchronous).  
+	The asynchronous method returns from the call immediately, so that processing can go on, while the results become available later.
+
+**Features**
+	* customizable caching validation resolver for synchronous and asynchronous lookups
+	* easy to use object interface
+	* easy to integrate extension module
+	* designed for thread environment (i.e. thread-safe)
+	* allows define and customize of local zone and its RR's during the operation (i.e. without restart)
+	* includes encoding functions to simplify the results retrieval
+	* Internationalized domain name (`IDN`_) support
+
+	.. _IDN: http://en.wikipedia.org/wiki/Internationalized_domain_name
+
+**Application area**
+	* DNS-based applications performing DNS lookups; the caching resolver can reduce overhead
+	* Applications where the validation of DNS records is required
+	* Great solution for customizable and dynamic DNS-based white/blacklists (spam rejection, connection rejection, ...) using the dynamic local zone manipulation

+
+		Canonical name for the result (the final cname). May be empty if no canonical name exists.
+
+	.. attribute:: answer_packet
+		
+		The DNS answer packet. Network formatted. Can contain DNSSEC types.
+
+	.. attribute:: havedata
+		
+		If there is any data, this property is true. If false, there was no data (nxdomain may be true, rcode can be set).
+
+	.. attribute:: secure
+		
+		True, if the result is validated securely.
+	 	False, if validation failed or domain queried has no security info.
+	 
+	  	It is possible to get a result with no data (havedata is false),
+	  	and secure is true. This means that the non-existance of the data
+	  	was cryptographically proven (with signatures).
+
+	.. attribute:: bogus
+		
+		If the result was not secure (secure==0), and this result is due  to a security failure, bogus is true.
+	 	This means the data has been actively tampered with, signatures
+	 	failed, expected signatures were not present, timestamps on 
+	 	signatures were out of date and so on.
+	 
+	 	If secure==0 and bogus==0, this can happen if the data is not secure 
+	 	because security is disabled for that domain name. 
+	 	This means the data is from a domain where data is not signed.
+
+	.. attribute:: nxdomain
+
+		If there was no data, and the domain did not exist, this is true. 
+		If it is false, and there was no data, then the domain name is purported to exist, but the requested data type is not available.
+
+	.. attribute:: rcode
+		
+		DNS RCODE for the result. May contain additional error code if there was no data due to an error. 
+		0 (RCODE_NOERROR) if okay. See predefined `RCODE_` constants.
+	
+		RCODE can be represented in display representation form (string) using :attr:`rcode_str` attribute.
