+1.6.13	2012-05-21
+	* New -S option for ldns-verify-zone to chase signatures online.
+	* New -k option for ldns-verify-zone to validate using a trusted key.
+	* New inception and expiration margin options (-i and -e) to 
+	  ldns-verify-zone.
+	* New ldns_dnssec_zone_new_frm_fp and ldns_dnssec_zone_new_frm_fp_l
+	  functions.
+	* New ldns_duration* functions (copied from OpenDNSSEC source)
+	* fix ldns-verify-zone to allow NSEC3 signatures to come before
+	  the NSEC3 RR in all cases. Thanks Wolfgang Nagele.
+	* Zero the correct flag (opt-out) when creating NSEC3PARAMS.
+	  Thanks Peter van Dijk.
+	* Canonicalize RRSIG's Signer's name too when validating, because 
+	  bind and unbound do that too. Thanks Peter van Dijk.
+	* bugfix #433: Allocate rdf using ldns_rdf_new in ldns_dname_label
+	* bugfix #432: Use LDNS_MALLOC & LDNS_FREE i.s.o. malloc & free
+	* bugfix #431: Added error message for LDNS_STATUS_INVALID_B32_EXT
+	* bugfix #427: Explicitely link ssl with the programs that use it.
+	* Fix reading \DDD: Error on values that are outside range (>255).
+	* bugfix #429: fix doxyparse.pl fails on NetBSD because specified
+	  path to perl.
+	* New ECDSA support (RFC 6605), use --disable-ecdsa for older openssl.
+	* fix verifying denial of existence for DS's in NSEC3 Opt-Out zones.
+	  Thanks John Barnitz
+
+1.6.12	2012-01-11
+	* bugfix #413: Fix manpage source for srcdir != builddir
+	* Canonicalize the signers name rdata field in RRSIGs when signing
+	* Ignore minor version of Private-key-format (so v1.3 may be used)
+	* Allow a check_time to be given in stead of always checking against
+	  the current time. With ldns-verify-zone the check_time can be set
+	  with the -t option.
+	* Added functions for updating and manipulating SOA serial numbers.
+	  ldns-read-zone has an option -S for updating and manipulating the
+	  serial numbers.
+	* The library Makefile is now GNU and BSD make compatible.
+	* bugfix #419: NSEC3 validation of a name covered by a wildcard with
+	  no data.
+	* Two new options (--with-drill and --with-examples) to the main
+	  configure script (in the root of the source tree) to build drill
+	  and examples too.
+	* Fix days_since_epoch to year_yday calculation on 32bits systems.
+
+1.6.11	2011-09-29
+	* bugfix #394: Fix socket leak on errors
+	* bugfix #392: Apex only and percentage checks for ldns-verify-zone
+	  (thanks Miek Gieben)
+	* bugfix #398: Allow NSEC RRSIGs before the NSEC3 in ldns-verify-zone
+	* Fix python site package path from sitelib to sitearch for pyldns.
+	* Fix python api to support python2 and python3 (thanks Karel Slany).
+	* bugfix #401: Correction of date/time functions algorithm and
+	  prevention of an infinite loop therein
+	* bugfix #402: Correct the minimum and maximum number of rdata fields
+	  in TSIG. (thanks David Keeler)
+	* bugfix #403: Fix heap overflow (thanks David Keeler)
+	* bugfix #404: Make parsing APL strings more robust
+	  (thanks David Keeler)
+	* bugfix #391: Complete library assessment to prevent assertion errors
+	  through ldns_rdf_size usage.
+	* Slightly more specific error messaging on wrong number of rdata
+	  fields with the LDNS_STATUS_MISSING_RDATA_FIELDS_RRSIG and
+	  LDNS_STATUS_MISSING_RDATA_FIELDS_KEY result codes.
+	* bugfix #406: More rigorous openssl result code handling to prevent
+	  future crashes within openssl.
+	* Fix ldns_fetch_valid_domain_keys to search deeper than just one level
+	  for a DNSKEY that signed a DS RR. (this function was used in the
+	  check_dnssec_trace nagios module)
+	* bugfix #407: Canonicalize TSIG dnames and algorithm fields
+	* A new output specifier to accommodate configuration of what to show
+	  in comment texts when converting host and/or wire-format data to
+	  string. All conversion to string and printing functions have a new
+	  version that have such a format specifier as an extra argument.
+	  The default is changed so that only DNSKEY RR's are annotated with
+	  an comment show the Key Tag of the DNSKEY.
+	* Fixed the ldns resolver to not mark a nameserver unreachable when
+	  edns0 is tried unsuccessfully with size 4096 (no return packet came),
+	  but to still try TCP. A big UDP packet might have been corrupted by
+	  fragments dropping firewalls.
+	* Update of libdns.vim (thanks Miek Gieben)
+	* Added the ldnsx Python module to our contrib section, which adds even
+	  more pythonisticism to the usage of ldns with  Python. (Many thanks
+	  to Christpher Olah and Paul Wouters)
+	  The ldnsx module is automatically installed when --with-pyldns is
+	  used with configuring, but may explicitly be excluded with the
+	  --without-pyldnsx option to configure.
+	* bugfix #410: Fix clearing out temporary data on stack in sha2.c
+	* bugfix #411: Don't let empty non-terminal NSEC3s cause assertion failure.
+
+1.6.10	2011-05-31
+	* New example tool added: ldns-gen-zone.
+	* bugfix #359: Serial-arithmetic for the inception and expiration
+	  fields of a RRSIG and correctly converting them to broken-out time
+	  information.
+	* bugfix #364: Slight performance increase of ldns-verifyzone.
+	* bugfix #367: Fix to allow glue records with the same name as the
+	  delegation.
+	* Fix ldns-verifyzone to allow NSEC3-less records for NS rrsets *and*
+	  glue when the zone is opt-out.
+	* bugfix #376: Adapt ldns_nsec3_salt, ldns_nsec3_iterations,
+	  ldns_nsec3_flags and ldns_nsec3_algorithm to work for NSEC3PARAMS too.
+	* pyldns memory leaks fixed by Bedrich Kosata (at the cost of a bit
+	  performance)
+	* Better handling of reference variables in ldns_rr_new_frm_fp_l from
+	  pyldns, with a very nice generator function by Bedrich Kosata.
+	* Decoupling of the rdfs in rrs in the python wrappers to enable
+	  the python garbage collector by Bedrich Kosata.
+	* bugfix #380: Minimizing effect of discrepancies in sizeof(bool) at
+	  build time and when used.
+	* bugfix #383: Fix detection of empty nonterminals of multiple labels.
+	* Fixed the ommission of rrsets in nsec(3)s and rrsigs to all occluded
+	  names (in stead of just the ones that contain glue only) and all
+	  occluded records on the delegation points (in stead of just the glue).
+	* Clarify the operation of ldns_dnssec_mark_glue and the usage of
+	  ldns_dnssec_node_next_nonglue functions in the documentation.
+	* Added function ldns_dnssec_mark_and_get_glue as an real fast
+	  alternative for ldns_zone_glue_rr_list.
+	* Fix parse buffer overflow for max length domain names.
+	* Fix Makefile for U in environment, since wrong U is more common than
+	  deansification necessity.

+1.6.4	2010-01-20
+	* Imported pyldns contribution by Zdenek Vasicek and Karel Slany.
+	  Changed its configure and Makefile to fit into ldns.
+	  Added its dname_* methods to the rdf_* class (as is the ldns API).
+	  Changed swig destroy of ldns_buffer class to ldns_buffer_free.
+	  Declared ldns_pkt_all and ldns_pkt_all_noquestion so swig sees them.
+	* Bugfix: parse PTR target of .tomhendrikx.nl with error not crash.
+	* Bugfix: handle escaped characters in TXT rdata.
+	* bug292: no longer crash on malformed domain names where a label is
+	  on position 255, which was a buffer overflow by one.
+	* Fix ldns_get_rr_list_hosts_frm_fp_l (strncpy to strlcpy change),
+	  which fixes resolv.conf reading badly terminated string buffers.
+	* Fix ldns_pkt_set_random_id to be more random, and a little faster,
+	  it did not do value 0 statistically correctly.
+	* Fix ldns_rdf2native_sockaddr_storage to set sockaddr type to zeroes,
+	  for portability.
+	* bug295: nsec3-hash routine no longer case sensitive.
+	* bug298: drill failed nsec3 denial of existence proof.
+
+1.6.3	2009-12-04

+
+1.6.2	2009-11-12
+	* Fix Makefile patch from Havard Eidnes, better install.sh usage.
+	* Fix parse error on SOA serial of 2910532839.
+	  Fix print of ';' and readback of '\;' in names, also for '\\'.
+	  Fix parse of '\(' and '\)' in names.  Also for file read. Also '\.'
+	* Fix signature creation when TTLs are different for RRs in RRset.
+	* bug273: fix so EDNS rdata is included in pkt to wire conversion.
+	* bug274: fix use of c++ keyword 'class' for RR class in the code.
+	* bug275: fix memory leak of packet edns rdata.
+	* Fix timeout procedure for TCP and AXFR on Solaris.
+	* Fix occasional NSEC bitmap bogus
+	* Fix rr comparing (was in reversed order since 1.6.0)
+	* bug278: fix parsing HINFO rdata (and other cases).
+	* Fix previous owner name: also pick up if owner name is @.
+	* RFC5702: enabled sha2 functions by default. This requires OpenSSL 0.9.8 or higher.
+      Reason for this default is the root to be signed with RSASHA256.
+	* Fix various LDNS RR parsing issues: IPSECKEY, WKS, NSAP, very long lines
+	* Fix: Make ldns_dname_is_subdomain case insensitive.
+	* Fix ldns-verify-zone so that address records at zone NS set are not considered glue
+		(Or glue records fall below delegation)
+    * Fix LOC RR altitude printing.
+	* Feature: Added period (e.g. '3m6d') support at explicit TTLs.
+    * Feature: DNSKEY rrset by default signed with minimal signatures
+		but -A option for ldns-signzone to sign it with all keys.
+		This makes the DNSKEY responses smaller for signed domains.
+
+1.6.1   2009-09-14
+	* --enable-gost : use the GOST algorithm (experimental).
+	* Added some missing options to drill manpage

+
+1.6.0
+	Additions:
+	* Addition of an ldns-config script which gives cflags and libs
+	  values, for use in configure scripts for applications that use
+	  use ldns. Can be disabled with ./configure --disable-ldns-config
+	* Added direct sha1, sha256, and sha512 support in ldns.
+	  With these functions, all NSEC3 functionality can still be
+	  used, even if ldns is built without OpenSSL. Thanks to OpenBSD,
+	  Steve Reid, and Aaron D. Gifford for the code.
+	* Added reading/writing support for the SPF Resource Record
+	* Base32 functions are now exported
+	Bugfixes:
+	* ldns_is_rrset did not go through the complete rrset, but
+	  only compared the first two records. Thanks to Olafur
+	  Gudmundsson for report and patch
+	* Fixed a small memory bug in ldns_rr_list_subtype_by_rdf(),
+	  thanks to Marius Rieder for finding an patching this.
+	* --without-ssl should now work. Make sure that examples/ and
+	  drill also get the --without-ssl flag on their configure, if
+	  this is used.
+	* Some malloc() return value checks have been added
+	* NSEC3 creation has been improved wrt to empty nonterminals,
+	  and opt-out.
+	* Fixed a bug in the parser when reading large NSEC3 salt
+	  values.
+	* Made the allowed length for domain names on wire
+	  and presentation format the same.
+	Example tools:
+	* ldns-key2ds can now also generate DS records for keys without
+	  the SEP flag
+	* ldns-signzone now equalizes the TTL of the DNSKEY RRset (to
+	  the first non-default DNSKEY TTL value it sees)
+
+1.5.1
+	Example tools:
+	* ldns-signzone was broken in 1.5.0 for multiple keys, this
+	  has been repaired
+
+	Build system:
+	* Removed a small erroneous output warning in
+	  examples/configure and drill/configure
+
+1.5.0
+	Bug fixes:
+	* fixed a possible memory overflow in the RR parser
+	* build flag fix for Sun Studio
+	* fixed a building race condition in the copying of header
+	  files
+	* EDNS0 extended rcode; the correct assembled code number
+	  is now printed (still in the EDNS0 field, though)
+	* ldns_pkt_rr no longer leaks memory (in fact, it no longer
+	  copies anything all)
+
+	API addition:
+	* ldns_key now has support for 'external' data, in which
+	  case the OpenSSL EVP structures are not used;
+	  ldns_key_set_external_key() and ldns_key_external_key()
+	* added ldns_key_get_file_base_name() which creates a
+	  'default' filename base string for key storage, of the
+	  form "K<zone>+<algorithm>+<keytag>"
+	* the ldns_dnssec_* family of structures now have deep_free()
+	  functions, which also free the ldns_rr's contained in them
+	* there is now an ldns_match_wildcard() function, which checks
+	  whether a domain name matches a wildcard name
+	* ldns_sign_public has been split up; this resulted in the
+	  addition of ldns_create_empty_rrsig() and
+	  ldns_sign_public_buffer()
+
+	Examples:
+	* ldns-signzone can now automatically add DNSKEY records when
+	  using an OpenSSL engine, as it already did when using key
+	  files
+	* added new example tool: ldns-nsec3-hash
+	* ldns-dpa can now filter on specific query name and types
+	* ldnsd has fixes for the zone name, a fix for the return
+	  value of recvfrom(), and an memory initialization fix
+	  (Thanks to Colm MacCárthaigh for the patch)
+	* Fixed memory leaks in ldnsd
+
+
+
+1.4.1
+	Bug fixes:
+	* fixed a build issue where ldns lib existence was done too early
+	* removed unnecessary check for pcap.h
+	* NSEC3 optout flag now correctly printed in string output
+	* inttypes.h moved to configured inclusion
+	* fixed NSEC3 type bitmaps for empty nonterminals and unsigned
+	  delegations
+
+	API addition:
+	* for that last fix, we added a new function
+	  ldns_dname_add_from() that can clone parts of a dname
+
+1.4.0

+		- ldns_rr_type2str
+		- ldns_rr_class2str
+		- ldns_rr_type2buffer_str
+		- ldns_rr_class2buffer_str
+	* buffer2str() is now called ldns_buffer2str
+	* base32 and base64 function names are now also prepended with ldns_
+	* ldns_rr_new_frm_str() now returns an error on missing RDATA fields.
+	  Since you cannot read QUESTION section RRs with this anymore,
+	  there is now a function called ldns_rr_new_question_frm_str()
+
+	LIBRARY FEATURES:
+	* DS RRs string representation now add bubblebabble in a comment
+	  (patch from Jakob Schlyter)
+	* DLV RR type added
+	* TCP fallback system has been improved
+	* HMAC-SHA256 TSIG support has been added.
+	* TTLS are now correcly set in NSEC(3) records when signing zones
+
+	EXAMPLE TOOLS:
+	* New example: ldns-revoke to revoke DNSKEYs according to RFC5011
+	* ldns-testpkts has been fixed and updated
+	* ldns-signzone now has the option to not add the DNSKEY
+	* ldns-signzone now has an (full zone only) opt-out option for
+	                NSEC3
+	* ldns-keygen can create HMAC-SHA1 and HMAC-SHA256 symmetric keys
+	* ldns-walk output has been fixed
+	* ldns-compare-zones has been fixed, and now has an option
+	  to show all differences (-a)
+	* ldns-read-zone now has an option to print DNSSEC records only
+
+1.3
+	Base library:
+
+	* Added a new family of functions based around ldns_dnssec_zone,
+	which is a new structure that keeps a zone sorted through an
+	rbtree and links signatures and NSEC(3) records directly to their
+	RRset. These functions all start with ldns_dnssec_
+
+	* ldns_zone_sign and ldns_zone_sign_nsec3 are now deprecated, but
+	have been changed to internally use the new
+	ldns_dnssec_zone_sign(_nsec3)
+
+	* Moved some ldns_buffer functions inline, so a clean rebuild of
+	applications relying on those is needed (otherwise you'll get
+	linker errors)
+	* ldns_dname_label now returns one extra (zero)
+	byte, so it can be seen as an fqdn.
+	* NSEC3 type code update for signing algorithms.
+	* DSA key generation of DNSKEY RRs fixed (one byte too small).
+
+	* Added support for RSA/SHA256 and RSA/SHA512, as specified in
+	draft-ietf-dnsext-dnssec-rsasha256-04. The typecodes are not
+	final, and this feature is not enabled by default. It can be
+	enabled at compilation time with the flag --with-sha2
+
+	* Added 2wire_canonical family of functions that lowercase dnames
+	in rdata fields in resource records of the types in the list in
+	rfc3597
+
+	* Added base32 conversion functions.
+
+	* Fixed DSA RRSIG conversion when calling OpenSSL
+
+	Drill:
+
+	* Chase output is completely different, it shows, in ascii, the
+	relations in the trust hierarchy.
+
+	Examples:
+	* Added ldns-verify-zone, that can verify the internal DNSSEC records
+	of a signed BIND-style zone file
+
+	* ldns-keygen now takes an -a argument specifying the algorithm,
+	instead of -R or -D. -a list show a list of supported algorithms
+
+	* ldns-keygen now defaults to the exponent RSA_F4 instead of RSA_3
+	for RSA key generation
+
+	* ldns-signzone now has support for HSMs
+	* ldns-signzone uses the new ldns_dnssec_ structures and functions
+	which improves its speed, and output; RRSIGS are now placed
+	directly after their RRset, NSEC(3) records directly after the
+	name they handle
+
+	Contrib:
+	* new contrib/ dir with user contributions
+	* added compilation script for solaris (thanks to Jakob Schlyter)
+
+28 Nov 2007 1.2.2:
+	* Added support for HMAC-MD5 keys in generator
+	* Added a new example tool (written by Ondrej Sury): ldns-compare-zones
+	* ldns-keygen now checks key sizes for rfc conformancy
+	* ldns-signzone outputs SSL error if present
+	* Fixed manpages (thanks to Ondrej Sury)
+	* Fixed Makefile for -j <x>
+	* Fixed a $ORIGIN error when reading zones
+	* Fixed another off-by-one error
+
+03 Oct 2007 1.2.1:
+	* Fixed an offset error in rr comparison
+	* Fixed ldns-read-zone exit code
+	* Added check for availability of SHA256 hashing algorithm
+	* Fixed ldns-key2ds -2 argument
+	* Fixed $ORIGIN bug in .key files
+	* Output algorithms as an integer instead of their mnemonic
+	* Fixed a memory leak in dnssec code when SHA256 is not available
+	* Updated fedora .spec file
+
+11 Apr 2007 1.2.0:
+	* canonicalization of rdata in DNSSEC functions now adheres to the
+	  rr type list in rfc3597, not rfc4035, which will be updated
+	  (see http://www.ops.ietf.org/lists/namedroppers/namedroppers.2007/msg00183.html)
+	* ldns-walk now support dnames with maximum label length
+	* ldnsd now takes an extra argument containing the address to listen on
+	* signing no longer signs every rrset with KSK's, but only the DNSKEY rrset
+	* ported to Solaris 10
+	* added ldns_send_buffer() function
+	* added ldns-testpkts fake packet server
+	* added ldns-notify to send NOTIFY packets
+	* ldns-dpa can now accurately calculate the number of matches per
+	  second
+	* libtool is now used for compilation too (still gcc, but not directly)
+	* Bugfixes:
+		- TSIG signing buffer size
+		- resolv.conf reading (comments)
+		- dname comparison off by one error
+		- typo in keyfetchers output file name fixed (a . too much)
+		- fixed zone file parser when comments contain ( or )
+		- fixed LOC RR type
+		- fixed CERT RR type
+
+	Drill:
+	* drill prints error on failed axfr.
+	* drill now accepts mangled packets with -f
+	* old -c option (use tcp) changed to -t
+	* -c option to specify alternative resolv.conf file added
+	* feedback of signature chase improved
+	* chaser now stops at root when no trusted keys are found
+	  instead of looping forever trying to find the DS for .
+	* Fixed bugs:
+		- wildcard on multiple labels signature verification
+		- error in -f packet writing for malformed packets
+		- made KSK check more resilient
+
+7 Jul 2006: 1.1.0: ldns-team
+	* Added tutorials and an introduction to the documentation
+	* Added include/ and lib/ dirs so that you can compile against ldns
+	  without installing ldns on your system
+	* Makefile updates
+	* Starting usage of assert throughout the library to catch illegal calls
+	* Solaris 9 testing was carried out. Ldns now compiles on that
+	  platform; some gnuism were identified and fixed.
+	* The ldns_zone structure was stress tested. The current setup
+	 (ie. just a list of rrs) can scale to zone file in order of
+	  megabytes. Sorting such zone is still difficult.
+	* Reading multiline b64 encoded rdata works.
+	* OpenSSL was made optional, configure --without-ssl.
+	  Ofcourse all dnssec/tsig related functions are disabled
+	* Building of examples and drill now happens with the same
+	  defines as the building of ldns itself.
+	* Preliminary sha-256 support was added. Currently is your
+	  OpenSSL supports it, it is supported in the DS creation.
+	* ldns_resolver_search was implemented
+	* Fixed a lot of bugs
+
+	Drill:
+	* -r was killed in favor of -o <header bit mnemonic> which
+	  allows for a header bits setting (and maybe more in the
+	  future)
+	* DNSSEC is never automaticaly set, even when you query
+	  for DNSKEY/RRSIG or DS.
+	* Implement a crude RTT check, it now distinguishes between
+	  reachable and unreachable.
+	* A form of secure tracing was added
+	* Secure Chasing has been improved
+	* -x does a reverse lookup for the given IP address
+
+	Examples:
+	* ldns-dpa was added to the examples - this is the Dns Packet
+	  Analyzer tool.
+	* ldnsd - as very, very simple nameserver impl.
+	* ldns-zsplit - split zones for parrallel signing
+	* ldns-zcat - cat split zones back together
+	* ldns-keyfetcher - Fetches DNSKEY records with a few (non-strong,
+	  non-DNSSEC) anti-spoofing techniques.
+	* ldns-walk - 'Walks' a DNSSEC signed zone
+	* Added an all-static target to the makefile so you can use examples
+	  without installing the library
+	* When building in the source tree or in a direct subdirectory of
+	  the build dir, configure does not need --with-ldns=../ anymore
+
+	Code:
+	* All networking code was moved to net.c
+	* rdata.c: added asserts to the rdf set/get functions
+	* const keyword was added to pointer arguments that
+	  aren't changed
+
+	API:
+	Changed:
+	* renamed ldns/dns.h to ldns/ldns.h
+	* ldns_rr_new_frm_str() is extented with an extra variable which
+	  in common use may be NULL. This trickles through to:
+	  o ldns_rr_new_frm_fp
+	  o ldns_rr_new_frm_fp_l
+	  Which also get an extra variable
+	  Also the function has been changed to return a status message.
+	  The compiled RR is returned in the first argument.
+	* ldns_zone_new_frm_fp_l()  and ldns_zone_new_frm_fp() are
+	  changed to return a status msg.
+	* ldns_key_new_frm_fp is changed to return ldns_status and
+	  the actual key list in the first argument
+	* ldns_rdata_new_frm_fp[_l]() are changed to return a status.
+	  the rdf is return in the first argument
+	* ldns_resolver_new_frm_fp: same treatment: return status and
+	  the new resolver in the first argument
+	* ldns_pkt_query_new_frm_str(): same: return status and the
+	  packet in the first arg
+	* tsig.h: internal used functions are now static:
+	  ldns_digest_name and ldns_tsig_mac_new
+	* ldns_key_rr2ds has an extra argument to specify the hash to
+	  use.
+	* ldns_pkt_rcode() is renamed to ldns_pkt_get_rcode, ldns_pkt_rcode
+	  is now the rcode type, like ldns_pkt_opcode
+	New:
+	* ldns_resolver_searchlist_count: return the searchlist counter
+	* ldns_zone_sort: Sort a zone
+	* ldns_bgsend(): background send, returns a socket.
+	* ldns_pkt_empty(): check is a packet is empty
+	* ldns_rr_list_pop_rr_list(): pop multiple rr's from another rr_list
+	* ldns_rr_list_push_rr_list(): push multiple rr's to an rr_list
+	* ldns_rr_list_compare(): compare 2 ldns_rr_lists
+	* ldns_pkt_push_rr_list: rr_list equiv for rr
+	* ldns_pkt_safe_push_rr_list: rr_list equiv for rr
+	Removed:
+	* ldns_resolver_bgsend(): was not used in 1.0.0 and is not used now
+	* ldns_udp_server_connect(): was faulty and isn't really part of
+	  the core ldns idea any how.
+	* ldns_rr_list_insert_rr(): obsoleted, because not used.
+	* char *_when was removed from the ldns_pkt structure
+
+18 Oct 2005: 1.0.0: ldns-team
+	* Commited a patch from Håkan Olsson
+	* Added UPDATE support (Jakob Schlyter and Håkan Olsson)
+	* License change: ldns is now BSD licensed
+	* ldns now depends on SSL
+	* Networking code cleanup, added (some) server udp/tcp support
+	* A zone type is introduced. Currently this is a list
+	  of RRs, so it will not scale well.
+	* [beta] Zonefile parsing was added
+	* [tools] Drill was added to ldns - see drill/
+	* [tools] experimental signer was added
+	* [building] better check for ssl
+	* [building] major revision of build system
+	* [building] added rpm .spec in packaging/ (thanks to Paul Wouters)
+	* [building] A lot of cleanup in the build scripts (thanks to Jakob Schlyter
+	and Paul Wouters)
+
+28 Jul 2005: 0.70: ldns-team
+	* [func] ldns_pkt_get_section now returns copies from the rrlists
+	  in the packet. This can be freed by the user program
+	* [code] added ldns_ prefixes to function from util.h
+	* [inst] removed documentation from default make install
+	* Usual fixes in documentation and code
+
+20 Jun 2005: 0.66: ldns-team
+	Rel. Focus: drill-pre2 uses some functions which are
+	not in 0.65
+	* dnssec_cd bit function was added
+	* Zone infrastructure was added
+	* Usual fixes in documentation and code
+
+13 Jun 2005: 0.65: ldns-team
+	* Repository is online at:
+	  http://www.nlnetlabs.nl/ldns/svn/
+	* Apply reference copying throuhgout ldns, except in 2
+	  places in the ldns_resolver structure (._domain and
+	 ._nameservers)
+	* Usual array of bugfixes
+	* Documentation added
+	* keygen.c added as an example for DNSSEC programming
+
+23 May 2005: 0.60: ldns-team
+	* Removed config.h from the header installed files
+	  (you're not supposed to include that in a libary)
+	* Further tweaking
+	  - DNSSEC signing/verification works
+	  - Assorted bug fixes and tweaks (memory management)
+
+May 2005: 0.50: ldns-team
+	* First usable release
+	* Basic DNS functionality works
+	* DNSSEC validation works

+        Your Support
+
+Project page:
+http://www.nlnetlabs.nl/ldns/
+On that page you can also subscribe to the ldns mailing list.
+
+* Development 
+ldns is mainly developed on Linux and FreeBSD. It is regularly tested to
+compile on other systems like Solaris and Mac OS X.
+
+REQUIREMENTS
+- OpenSSL (Optional, but needed for features like DNSSEC)
+- libpcap (Optional, but needed for examples/ldns-dpa)
+- (GNU) libtool (in OSX, that's glibtool, not libtool)
+- GNU make
+
+INSTALLATION
+1. Unpack the tarball
+2. cd ldns-<VERSION>
+3. ./configure
+4. gmake (it needs gnu make to compile, on systems where GNU make is the
+   default you can just use 'make')
+5. sudo gmake install
+6. Optional. (cd examples; ./configure; gmake), make example programs included.
+7. Optional. (cd drill; ./configure; gmake; gmake install), to build drill.
+
+You can configure and compile it in a separate build directory.
+
+* Examples
+There are some examples and dns related tools in the examples/ directory.
+These can be built with:
+1. cd examples/
+2. ./configure [--with-ldns=<path to ldns installation or build>]
+3. gmake
+
+* Drill
+Drill can be built with:
+1. cd drill/
+2. ./configure [--with-ldns=<path to ldns installation or build>]
+3. gmake
+
+Note that you need to set LD_LIBRARY_PATH if you want to run the binaries
+and you have not installed the library to a system directory. You can use
+the make target all-static for the examples to run them if you don't want to
+install the library.
+
+
+* Building from subversion repository
+
+If you are building from the repository you will need to have (gnu)
+autotools like libtool and autoreconf installed. A list of all the commands
+needed to build everything can be found in README.svn. Note that the actual
+commands may be a little bit different on your machine. Most notable, you'll need to run libtoolize (or glibtoolize), if you skip this step, you'll get an error about missing config.sub.
+
+* Developers
+ldns is developed by the ldns team at NLnet Labs. This team currently
+consists of:
+  o Willem Toorop
+  o Wouter Wijngaards
+  o Matthijs Mekking
+
+Former main developers:
+  o Jelte Jansen
+  o Miek Gieben
+
+* Credits
+We have received patches from the following people, thanks!
+  o Bedrich Kosata
+  o Erik Rozendaal
+  o Håkan Olsson
+  o Jakob Schlyter
+  o Paul Wouters
+  o Simon Vallet
+  o Ondřej Surý
+
+
+INFORMATION FOR SPECIFIC OPERATING SYSTEMS
+
+MAC OS X
+
+For MACOSX 10.4 and later, it seems that you have to set the
+MACOSX_DEPLOYMENT_TARGET environment variable to 10.4 before running
+make. Apparently it defaults to 10.1.
+
+This appears to be a known problem in 10.2 to 10.4, see:
+http://developer.apple.com/qa/qa2001/qa1233.html
+for more information.
+
+
+SOLARIS
+
+In Solaris multi-architecture systems (that have both 32-bit and
+64-bit support), it can be a bit taxing to convince the system to
+compile in 64-bit mode. Jakob Schlyter has kindly contributed a build
+script that sets the right build and link options. You can find it in
+contrib/build-solaris.sh
+
+KNOWN ISSUES
+
+A complete list of currently known open issues can be found here:
+http://www.nlnetlabs.nl/projects/ldns/bugs
+
+* pyldns
+Compiling pyldns produces many ``unused parameter'' warnings.  Those are
+harmless and may safely be ignored.
+Also when building with Swig which version is before 2.0.4, compiling
+pyldns produces many ``missing initializer'' warnings. Those are harmless
+too.
+
+Your Support
+NLnet Labs offers all of its software products as open source, most are
+published under a BDS license. You can download them, not only from the
+NLnet Labs website but also through the various OS distributions for
+which NSD, ldns, and Unbound are packaged. We therefore have little idea
+who uses our software in production environments and have no direct ties
+with 'our customers'.
+
+Therefore, we ask you to contact us at users@NLnetLabs.nl and tell us
+whether you use one of our products in your production environment,
+what that environment looks like, and maybe even share some praise.
+We would like to refer to the fact that your organization is using our
+products. We will only do that if you explicitly allow us. In all other
+cases we will keep the information you share with us to ourselves.
+
+In addition to the moral support you can also support us
+financially. NLnet Labs is a recognized not-for-profit charity foundation
+that is chartered to develop open-source software and open-standards
+for the Internet. If you use our software to satisfaction please express
+that by giving us a donation. For small donations PayPal can be used. For
+larger and regular donations please contact us at users@NLnetLabs.nl. Also
+see http://www.nlnetlabs.nl/labs/contributors/.

+# These exist entirely to fool aclocal when bootstrapping libtool.

+# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
+# which have later been changed to m4_define as they aren't part of the
+# exported API, or moved to Autoconf or Automake where they belong.
+#
+# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
+# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
+# using a macro with the same name in our local m4/libtool.m4 it'll
+# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
+# and doesn't know about Autoconf macros at all.)
+#
+# So we provide this file, which has a silly filename so it's always
+# included after everything else.  This provides aclocal with the
+# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
+# because those macros already exist, or will be overwritten later.
+# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
+#
+# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.

+# SYNOPSIS
+#
+#   AX_PKG_SWIG([major.minor.micro], [action-if-found], [action-if-not-found])
+#
+# DESCRIPTION
+#
+#   This macro searches for a SWIG installation on your system. If found,
+#   then SWIG is AC_SUBST'd; if not found, then $SWIG is empty.  If SWIG is
+#   found, then SWIG_LIB is set to the SWIG library path, and AC_SUBST'd.
+#
+#   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), AX_PKG_SWIG checks that the swig package is this version number
+#   or higher.
+#
+#   As usual, action-if-found is executed if SWIG is found, otherwise
+#   action-if-not-found is executed.
+#
+#   In configure.in, use as:
+#
+#     AX_PKG_SWIG(1.3.17, [], [ AC_MSG_ERROR([SWIG is required to build..]) ])
+#     AX_SWIG_ENABLE_CXX
+#     AX_SWIG_MULTI_MODULE_SUPPORT

+# SYNOPSIS
+#
+#   AX_PYTHON_DEVEL([version])
+#
+# DESCRIPTION
+#
+#   Note: Defines as a precious variable "PYTHON_VERSION". Don't override it
+#   in your configure.ac.
+#
+#   This macro checks for Python and tries to get the include path to
+#   'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS)
+#   output variables. It also exports $(PYTHON_EXTRA_LIBS) and
+#   $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code.
+#
+#   You can search for some particular version of Python by passing a
+#   parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please
+#   note that you *have* to pass also an operator along with the version to
+#   match, and pay special attention to the single quotes surrounding the
+#   version number. Don't use "PYTHON_VERSION" for this: that environment
+#   variable is declared as precious and thus reserved for the end-user.
+#
+#   This macro should work for all versions of Python >= 2.1.0. As an end
+#   user, you can disable the check for the python version by setting the
+#   PYTHON_NOVERSIONCHECK environment variable to something else than the
+#   empty string.
+#
+#   If you need to use this macro for an older Python version, please
+#   contact the authors. We're always open for feedback.

+5.  Base 32 Encoding
+
+   The Base 32 encoding is designed to represent arbitrary sequences of
+   octets in a form that needs to be case insensitive but need not be
+   humanly readable.
+
+   A 33-character subset of US-ASCII is used, enabling 5 bits to be
+   represented per printable character.  (The extra 33rd character, "=",
+   is used to signify a special processing function.)
+
+   The encoding process represents 40-bit groups of input bits as output
+   strings of 8 encoded characters.  Proceeding from left to right, a
+   40-bit input group is formed by concatenating 5 8bit input groups.
+   These 40 bits are then treated as 8 concatenated 5-bit groups, each
+   of which is translated into a single digit in the base 32 alphabet.
+   When encoding a bit stream via the base 32 encoding, the bit stream
+   must be presumed to be ordered with the most-significant-bit first.
+   That is, the first bit in the stream will be the high-order bit in
+   the first 8bit byte, and the eighth bit will be the low-order bit in
+   the first 8bit byte, and so on.
+
+   Each 5-bit group is used as an index into an array of 32 printable
+   characters.  The character referenced by the index is placed in the
+   output string.  These characters, identified in Table 3, below, are
+   selected from US-ASCII digits and uppercase letters.
+
+                      Table 3: The Base 32 Alphabet
+
+         Value Encoding  Value Encoding  Value Encoding  Value Encoding

+             1 B            10 K            19 T            28 4
+             2 C            11 L            20 U            29 5
+             3 D            12 M            21 V            30 6
+             4 E            13 N            22 W            31 7
+             5 F            14 O            23 X

+             8 I            17 R            26 2
+
+
+   Special processing is performed if fewer than 40 bits are available
+   at the end of the data being encoded.  A full encoding quantum is
+   always completed at the end of a body.  When fewer than 40 input bits
+   are available in an input group, zero bits are added (on the right)
+   to form an integral number of 5-bit groups.  Padding at the end of
+   the data is performed using the "=" character.  Since all base 32
+   input is an integral number of octets, only the following cases can
+   arise:
+
+   (1) the final quantum of encoding input is an integral multiple of 40
+   bits; here, the final unit of encoded output will be an integral
+   multiple of 8 characters with no "=" padding,
+
+   (2) the final quantum of encoding input is exactly 8 bits; here, the
+   final unit of encoded output will be two characters followed by six
+   "=" padding characters,
+
+   (3) the final quantum of encoding input is exactly 16 bits; here, the
+   final unit of encoded output will be four characters followed by four
+   "=" padding characters,
+
+   (4) the final quantum of encoding input is exactly 24 bits; here, the
+   final unit of encoded output will be five characters followed by
+   three "=" padding characters, or
+
+   (5) the final quantum of encoding input is exactly 32 bits; here, the
+   final unit of encoded output will be seven characters followed by one
+   "=" padding character.
+
+
+6.  Base 32 Encoding with Extended Hex Alphabet
+
+   The following description of base 32 is due to [7].  This encoding
+   should not be regarded as the same as the "base32" encoding, and
+   should not be referred to as only "base32".
+
+   One property with this alphabet, that the base64 and base32 alphabet
+   lack, is that encoded data maintain its sort order when the encoded
+   data is compared bit-wise.
+
+   This encoding is identical to the previous one, except for the
+   alphabet.  The new alphabet is found in table 4.

+5.  Base 32 Encoding
+
+   The Base 32 encoding is designed to represent arbitrary sequences of
+   octets in a form that needs to be case insensitive but need not be
+   humanly readable.
+
+   A 33-character subset of US-ASCII is used, enabling 5 bits to be
+   represented per printable character.  (The extra 33rd character, "=",
+   is used to signify a special processing function.)
+
+   The encoding process represents 40-bit groups of input bits as output
+   strings of 8 encoded characters.  Proceeding from left to right, a
+   40-bit input group is formed by concatenating 5 8bit input groups.
+   These 40 bits are then treated as 8 concatenated 5-bit groups, each
+   of which is translated into a single digit in the base 32 alphabet.
+   When encoding a bit stream via the base 32 encoding, the bit stream
+   must be presumed to be ordered with the most-significant-bit first.
+   That is, the first bit in the stream will be the high-order bit in
+   the first 8bit byte, and the eighth bit will be the low-order bit in
+   the first 8bit byte, and so on.
+
+   Each 5-bit group is used as an index into an array of 32 printable
+   characters.  The character referenced by the index is placed in the
+   output string.  These characters, identified in Table 3, below, are
+   selected from US-ASCII digits and uppercase letters.
+
+                      Table 3: The Base 32 Alphabet

+             8 I            17 R            26 2
+
+
+   Special processing is performed if fewer than 40 bits are available
+   at the end of the data being encoded.  A full encoding quantum is
+   always completed at the end of a body.  When fewer than 40 input bits
+   are available in an input group, zero bits are added (on the right)
+   to form an integral number of 5-bit groups.  Padding at the end of
+   the data is performed using the "=" character.  Since all base 32
+   input is an integral number of octets, only the following cases can
+   arise:
+
+   (1) the final quantum of encoding input is an integral multiple of 40
+   bits; here, the final unit of encoded output will be an integral
+   multiple of 8 characters with no "=" padding,
+
+   (2) the final quantum of encoding input is exactly 8 bits; here, the
+   final unit of encoded output will be two characters followed by six
+   "=" padding characters,
+
+   (3) the final quantum of encoding input is exactly 16 bits; here, the
+   final unit of encoded output will be four characters followed by four
+   "=" padding characters,
+
+   (4) the final quantum of encoding input is exactly 24 bits; here, the
+   final unit of encoded output will be five characters followed by
+   three "=" padding characters, or
+
+   (5) the final quantum of encoding input is exactly 32 bits; here, the
+   final unit of encoded output will be seven characters followed by one
+   "=" padding character.
+
+
+6.  Base 32 Encoding with Extended Hex Alphabet
+
+   The following description of base 32 is due to [7].  This encoding
+   should not be regarded as the same as the "base32" encoding, and
+   should not be referred to as only "base32".
+
+   One property with this alphabet, that the base32 and base32 alphabet
+   lack, is that encoded data maintain its sort order when the encoded
+   data is compared bit-wise.
+
+   This encoding is identical to the previous one, except for the
+   alphabet.  The new alphabet is found in table 4.

+/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
+   The following encoding technique is taken from RFC 1521 by Borenstein
+   and Freed.  It is reproduced here in a slightly edited form for
+   convenience.
+
+   A 65-character subset of US-ASCII is used, enabling 6 bits to be
+   represented per printable character. (The extra 65th character, "=",
+   is used to signify a special processing function.)
+
+   The encoding process represents 24-bit groups of input bits as output
+   strings of 4 encoded characters. Proceeding from left to right, a
+   24-bit input group is formed by concatenating 3 8-bit input groups.
+   These 24 bits are then treated as 4 concatenated 6-bit groups, each
+   of which is translated into a single digit in the base64 alphabet.
+
+   Each 6-bit group is used as an index into an array of 64 printable
+   characters. The character referenced by the index is placed in the
+   output string.

+/* (From RFC1521 and draft-ietf-dnssec-secext-03.txt)
+   The following encoding technique is taken from RFC 1521 by Borenstein
+   and Freed.  It is reproduced here in a slightly edited form for
+   convenience.
+
+   A 65-character subset of US-ASCII is used, enabling 6 bits to be
+   represented per printable character. (The extra 65th character, "=",
+   is used to signify a special processing function.)
+
+   The encoding process represents 24-bit groups of input bits as output
+   strings of 4 encoded characters. Proceeding from left to right, a
+   24-bit input group is formed by concatenating 3 8-bit input groups.
+   These 24 bits are then treated as 4 concatenated 6-bit groups, each
+   of which is translated into a single digit in the base64 alphabet.
+
+   Each 6-bit group is used as an index into an array of 64 printable
+   characters. The character referenced by the index is placed in the
+   output string.

+
+   Special processing is performed if fewer than 24 bits are available
+   at the end of the data being encoded.  A full encoding quantum is
+   always completed at the end of a quantity.  When fewer than 24 input
+   bits are available in an input group, zero bits are added (on the
+   right) to form an integral number of 6-bit groups.  Padding at the
+   end of the data is performed using the '=' character.
+
+   Since all base64 input is an integral number of octets, only the
+         -------------------------------------------------                       
+   following cases can arise:
+   
+       (1) the final quantum of encoding input is an integral
+           multiple of 24 bits; here, the final unit of encoded
+	   output will be an integral multiple of 4 characters
+	   with no "=" padding,
+       (2) the final quantum of encoding input is exactly 8 bits;
+           here, the final unit of encoded output will be two
+	   characters followed by two "=" padding characters, or
+       (3) the final quantum of encoding input is exactly 16 bits;
+           here, the final unit of encoded output will be three
+	   characters followed by one "=" padding character.

+ * Original:
+ * Patrick Powell Tue Apr 11 09:48:21 PDT 1995
+ * A bombproof version of doprnt (dopr) included.
+ * Sigh.  This sort of thing is always nasty do deal with.  Note that
+ * the version here does not include floating point...
+ *
+ * snprintf() is used instead of sprintf() as it does limit checks
+ * for string length.  This covers a nasty loophole.
+ *
+ * The other functions are there to prevent NULL pointers from
+ * causing nast effects.
+ *
+ * More Recently:
+ *  Brandon Long (blong@fiction.net) 9/15/96 for mutt 0.43
+ *  This was ugly.  It is still ugly.  I opted out of floating point
+ *  numbers, but the formatter understands just about everything
+ *  from the normal C string format, at least as far as I can tell from
+ *  the Solaris 2.5 printf(3S) man page.
+ *
+ *  Brandon Long (blong@fiction.net) 10/22/97 for mutt 0.87.1
+ *    Ok, added some minimal floating point support, which means this
+ *    probably requires libm on most operating systems.  Don't yet
+ *    support the exponent (e,E) and sigfig (g,G).  Also, fmtint()
+ *    was pretty badly broken, it just wasn't being exercised in ways
+ *    which showed it, so that's been fixed.  Also, formated the code
+ *    to mutt conventions, and removed dead code left over from the
+ *    original.  Also, there is now a builtin-test, just compile with:
+ *           gcc -DTEST_SNPRINTF -o snprintf snprintf.c -lm
+ *    and run snprintf for results.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+  CPP         C preprocessor
+  PYTHON_VERSION
+              The installed Python version to use, for example '2.3'. This
+              string will be appended to the Python interpreter canonical
+              name.
+
+Use these variables to override the choices made by `configure' or to help

+# SYNOPSIS
+#
+#   AX_PYTHON_DEVEL([version])
+#
+# DESCRIPTION
+#
+#   Note: Defines as a precious variable "PYTHON_VERSION". Don't override it
+#   in your configure.ac.
+#
+#   This macro checks for Python and tries to get the include path to
+#   'Python.h'. It provides the $(PYTHON_CPPFLAGS) and $(PYTHON_LDFLAGS)
+#   output variables. It also exports $(PYTHON_EXTRA_LIBS) and
+#   $(PYTHON_EXTRA_LDFLAGS) for embedding Python in your code.
+#
+#   You can search for some particular version of Python by passing a
+#   parameter to this macro, for example ">= '2.3.1'", or "== '2.4'". Please
+#   note that you *have* to pass also an operator along with the version to
+#   match, and pay special attention to the single quotes surrounding the
+#   version number. Don't use "PYTHON_VERSION" for this: that environment
+#   variable is declared as precious and thus reserved for the end-user.
+#
+#   This macro should work for all versions of Python >= 2.1.0. As an end
+#   user, you can disable the check for the python version by setting the
+#   PYTHON_NOVERSIONCHECK environment variable to something else than the
+#   empty string.
+#
+#   If you need to use this macro for an older Python version, please
+#   contact the authors. We're always open for feedback.

+# Finally, this is the expansion that is picked up by

+#   AX_PKG_SWIG([major.minor.micro], [action-if-found], [action-if-not-found])
+#
+# DESCRIPTION
+#
+#   This macro searches for a SWIG installation on your system. If found,
+#   then SWIG is AC_SUBST'd; if not found, then $SWIG is empty.  If SWIG is
+#   found, then SWIG_LIB is set to the SWIG library path, and AC_SUBST'd.
+#
+#   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), AX_PKG_SWIG checks that the swig package is this version number
+#   or higher.
+#
+#   As usual, action-if-found is executed if SWIG is found, otherwise
+#   action-if-not-found is executed.
+#
+#   In configure.in, use as:
+#
+#     AX_PKG_SWIG(1.3.17, [], [ AC_MSG_ERROR([SWIG is required to build..]) ])

+LDNSX: Easy DNS (including DNSSEC) via ldns.
+
+ldns is a great library. It is a powerfull tool for
+working with DNS. python-ldns it is a straight up clone of the C
+interface, howver that is not a very good interface for python. Its
+documentation is incomplete and some functions don't work as
+described. And some objects don't have a full python API.
+
+ldnsx aims to fix this. It wraps around the ldns python bindings,
+working around its limitations and providing a well-documented, more
+pythonistic interface.
+
+Written by Christopher Olah <chris@xelerance.com>
+
+Examples
+========
+
+Query the default resolver for google.com's A records. Print the response
+packet.
+
+>>> import ldnsx
+>>> resolver = ldnsx.resolver()
+>>> print resolver.query("google.com","A")
+
+Print the NS records for com. from f.root-servers.net if we get a
+response, else an error message.
+
+>>> import ldnsx
+>>> pkt = ldnsx.resolver("f.root-servers.net").query("com.","NS")
+>>> if pkt:
+>>>    for rr in pkt.answer():
+>>>       print rr
+>>> else:
+>>>    print "response not received"

+Welcome to ldnsx's documentation!
+=================================
+
+LDNSX: Easy DNS (including DNSSEC) via ldns.
+
+ldns is a great library. It is a powerfull tool for
+working with DNS. python-ldns it is a straight up clone of the C
+interface, howver that is not a very good interface for python. Its
+documentation is incomplete and some functions don't work as
+described. And some objects don't have a full python API.
+
+ldnsx aims to fix this. It wraps around the ldns python bindings,
+working around its limitations and providing a well-documented, more
+pythonistic interface.

+Resolving the MX records
+==============================
+
+This basic example shows how to create a resolver which asks for MX records which contain the information about mail servers.
+
+::
+
+	#!/usr/bin/python
+	#
+	# MX is a small program that prints out the mx records for a particular domain
+	#
+	import ldns
+	
+	resolver = ldns.ldns_resolver.new_frm_file("/etc/resolv.conf")
+
+	dname = ldns.ldns_dname("nic.cz")
+	
+	pkt = resolver.query(dname, ldns.LDNS_RR_TYPE_MX, ldns.LDNS_RR_CLASS_IN, ldns.LDNS_RD)
+	if (pkt):
+		mx = pkt.rr_list_by_type(ldns.LDNS_RR_TYPE_MX, ldns.LDNS_SECTION_ANSWER)
+		if (mx):
+			mx.sort()
+			print mx
+
+Resolving step by step
+------------------------
+
+First of all we import :mod:`ldns` extension module which make LDNS functions and classes accessible::
+
+	import ldns
+
+If importing fails, it means that Python cannot find the module or ldns library.
+
+Then we create the resolver by :meth:`ldns.ldns_resolver.new_frm_file` constructor ::
+
+	resolver = ldns.ldns_resolver.new_frm_file("/etc/resolv.conf")
+
+and domain name variable dname::
+
+	dname = ldns.ldns_dname("nic.cz")
+
+To create a resolver you may also use::
+
+	resolver = ldns.ldns_resolver.new_frm_file(None)
+
+which behaves in the same manner as the command above.
+
+In the third step we tell the resolver to query for our domain, type MX, of class IN::
+	
+	pkt = resolver.query(dname, ldns.LDNS_RR_TYPE_MX, ldns.LDNS_RR_CLASS_IN, ldns.LDNS_RD)
+
+The function should return a packet if everything goes well and this packet will contain resource records we asked for. 
+Note that there exists a simplier way. Instead of using a dname variable, we can use a string which will be automatically converted.
+::
+
+	pkt = resolver.query("fit.vutbr.cz", ldns.LDNS_RR_TYPE_MX, ldns.LDNS_RR_CLASS_IN, ldns.LDNS_RD)
+
+Now, we test whether the resolver returns a packet and then get all RRs of type MX from the answer packet and store them in list mx::
+
+	if (pkt):
+		mx = pkt.rr_list_by_type(ldns.LDNS_RR_TYPE_MX, ldns.LDNS_SECTION_ANSWER)
+
+If this list is not empty, we sort and print the content to stdout::
+
+	if (mx):
+		mx.sort()
+		print mx

+
+Querying DNS-SEC validators
+===========================
+
+This basic example shows how to query validating resolver and
+evaluate answer.
+
+Resolving step by step
+------------------------
+
+For DNS queries, we need to initialize ldns resolver (covered in previous example).
+   
+::
+   
+   # Create resolver
+   resolver = ldns.ldns_resolver.new_frm_file("/etc/resolv.conf")
+   resolver.set_dnssec(True)
+
+   # Custom resolver
+   if argc > 2:
+      # Clear previous nameservers
+      ns = resolver.pop_nameserver()
+      while ns != None:
+         ns = resolver.pop_nameserver()
+      ip = ldns.ldns_rdf.new_frm_str(sys.argv[2], ldns.LDNS_RDF_TYPE_A)
+      resolver.push_nameserver(ip)
+
+Note the second line :meth:`resolver.set_dnssec`, which enables DNSSEC OK bit
+in queries in order to get meaningful results.
+
+As we have resolver initialized, we can start querying for domain names :
+
+::
+   
+   # Resolve DNS name
+   pkt = resolver.query(name, ldns.LDNS_RR_TYPE_A, ldns.LDNS_RR_CLASS_IN)
+   if pkt and pkt.answer():
+
+Now we evaluate result, where two flags are crucial :
+
+ * Return code
+ * AD flag (authenticated)
+
+When return code is `SERVFAIL`, it means that validating resolver marked requested
+name as **bogus** (or bad configuration).
+
+**AD** flag is set if domain name is authenticated **(secure)** or false if
+it's insecure.
+
+Complete source code
+--------------------
+
+ .. literalinclude:: ../../../examples/ldns-dnssec.py
+    :language: python
+
+
+Testing
+-------
+
+In order to get meaningful results, you have to enter IP address of validating
+resolver or setup your own (see howto).
+
+Execute `./example2.py` with options `domain name` and `resolver IP`,
+example:
+
+::
+
+   user@localhost# ./example2.py www.dnssec.cz 127.0.0.1 # Secure (Configured Unbound running on localhost)
+   user@localhost# ./example2.py www.rhybar.cz 127.0.0.1 # Bogus
+
+Howto setup Unbound as validating resolver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Install Unbound according to instructions.
+Modify following options in `unbound.conf` (located in `/etc` or `/usr/local/etc`)/
+
+
+Uncomment `module-config` and set `validator` before iterator.
+
+::
+
+   module-config: "validator iterator"
+
+Download DLV keys and update path in `unbound.conf`::
+
+   # DLV keys
+   # Download from http://ftp.isc.org/www/dlv/dlv.isc.org.key
+   dlv-anchor-file: "/usr/local/etc/unbound/dlv.isc.org.key"
+
+Update trusted keys (`.cz` for example)::
+
+   # Trusted keys
+   # For current key, see www.dnssec.cz
+   trusted-keys-file: "/usr/local/etc/unbound/trusted.key"
+   
+Now you should have well configured Unbound, so run it::
+
+   user@localhost# unbound -dv
+

+Signing of a zone file
+===============================
+
+This example shows how to sign the content of the given zone file
+
+.. literalinclude:: ../../../examples/ldns-signzone.py
+   :language: python
+
+In order to be able sign a zone file, you have to generate a key-pair using ``ldns-keygen.py``. Don't forget to modify tag number.
+
+Signing consists of three steps
+
+1. In the first step, the content of a zone file is readed and parsed. This can be done using :class:`ldns.ldns_zone` class.
+
+2. In the second step, the private and public key is readed and public key is inserted into zone (as DNSKEY). 
+
+3. In the last step, the DNSSEC zone instace is created and all the RRs from zone file are copied here. Then, all the records are signed using :meth:`ldns.ldns_zone.sign` method. If the signing was successfull, the content of DNSSEC zone is written to a file.

+PyLDNS documentation
+=======================================
+
+PyLDNS provides an `LDNS`_ wrapper (Python extension module) - the thinnest layer over the library possible.  Everything you can do from the C API, you can do from Python, but with less effort. The purpose of porting LDNS library to Python is to simplify DNS programming and usage of LDNS, however, still preserve the performance of this library as the speed represents the main benefit of LDNS. The proposed object approach allows the users to be concentrated at the essential part of application only and don't bother with deallocation of objects and so on.

+Installation
+===================================
+
+**Prerequisites**
+
+Python 2.4 or higher, SWIG 1.3 or higher, GNU make
+
+**Download**
+
+You can download the source codes `here`_.
+The latest release is 1.4.1, Jan 15, 2009.
+
+.. _here: ldns-1.4.1-py.tar.gz
+
+**Compiling**
+
+After downloading, you can compile the library by doing::
+
+	> tar -xzf ldns-1.4.1-py.tar.gz
+	> cd ldns-1.4.1
+	> ./configure --with-pyldns
+	> make
+
+You need GNU make to compile pyLDNS; SWIG and Python development libraries to compile extension module. 
+
+
+**Testing**
+
+If the compilation is successfull, you can test the python LDNS extension module by::
+
+	> cd contrib/python
+	> make testenv
+	> ./ldns-mx.py
+
+This will start a new shell, during which the symbolic links will be working. 
+When you exit the shell, then symbolic links will be deleted. 
+
+In ``contrib/examples`` you can find many simple applications in python which demostrates the capabilities of LDNS library.
+
+**Installation**
+
+To install libraries and extension type::
+
+	> cd ldns-1.4.1
+	> make install
+

+LDNS module documentation
+================================
+
+Here you can find the documentation of pyLDNS extension module. This module consists of several classes and a couple of functions.
+
+.. toctree::
+	:maxdepth: 1
+	:glob:
+
+	ldns_resolver
+	ldns_pkt
+	ldns_rr
+	ldns_rdf
+	ldns_dname
+	ldns_rr_list
+	ldns_zone
+	ldns_key
+	ldns_key_list
+	ldns_buffer
+	ldns_dnssec
+	ldns_func
+
+
+
+
+**Differences against libLDNS**
+
+* You don't need to use ldns-compare functions, instances can be compared using standard operators <, >, = ::
+	
+	if (some_rr.owner() == another_rr.rdf(1)):
+		pass
+
+* Classes contain static methods that create new instances, the name of these methods starts with the new\_ prefix (e.g. :meth:`ldns.ldns_pkt.new_frm_file`).
+
+* Is it possible to print the content of an object using ``print objinst`` (see :meth:`ldns.ldns_resolver.get_addr_by_name`).
+
+* Classes contain write_to_buffer method that writes the content into buffer.
+
+* All the methods that consume parameter of (const ldns_rdf) type allows to use string instead (see :meth:`ldns.ldns_resolver.query`).

+This class can contains all types of keys that are used in DNSSEC. Mostly used to store private keys, since public keys can also be stored in a ldns_rr with type LDNS_RR_TYPE_DNSKEY. This class can also store some variables that influence the signatures generated by signing with this key, for instance the inception date.

+**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. (

+The libdns coding style guide
+
+* Use of tabs (real tabs, 8 positions long)
+* Spaces only after comma's, and in between operators.
+  And after keywords (if, while, for)
+* Underscores to make long names readable
+* prefix (exported) identifiers with 'ldns_'
+* no unneeded parentheses after 'return'
+* always curly brackets in if-statements
+* use defines for (weird) constants, and masks
+* type 'bool', constants 'true'/'false'. Don't compare bools for
+  equality.
+* always use LDNS_MALLOC/FREE etc, or the new/free/deep_free functions
+* buffer can scale, so don't alloc the max size, but the min size
+* make lint (uses splint) is your friend
+
+
+* Return values:
+	- status code (structure to fill is usually passed as a first argument)
+	- new/pointer: return pointer or NULL on error
+	- 'read' functions: ldns_status wire2thing(uint8_t *p, size_t max,
+	                                           size_t pos, *thing);
+	- void functions like ldns_rr_free
+	- bool functions
+
+* Parameter sequence: (dest, [dest_meta, ] src, [src_meta] etc)
+* structure/union field names start with _ when "private"
+* enum for rcode, opcode, types etc,
+	example:
+	enum ldns_rcode {
+		LDNS_RCODE_OK = 0,
+		...      = .,
+		LDNS_RCODE_FIRST = LDNS_RCODE_OK,
+		LDNS_RCODE_LAST = 15,	
+		LDNS_RCODE_COUNT = LDNS_RCODE_LAST + 1
+	}
+* Everything by reference, all data structures an optional _clone() function
+* arrays: ps[] with size_t p_count for the number of elements
+* _size for size in bytes
+* _free and _clone copies perform deep free/copy.
+
+* Standard abbreviations, don't abbreviate other names:
+
+    id          = identity
+    rr          = resource record
+    rrset       = resource record set

+* Configure option for not printing DNSSEC RR comments
+* HMAC and MD5 without OpenSSL
+* HIP RR support
+* Parse 'search' attribute in /etc/resolv.conf
+* Make use of automake (Bug #173)

+* Drill: print appropriate DS RRs (relates to Bug #355)
+* ldns-signzone optout to be really optout
+* Compression when generating wireformat. Preferably with a configurable

+
+Bugfixes:
+* Bug #279: fix return values for net.h functions, and related: make return

+/** \page design Design
+
+The following image shows the various modules of libdns and their
+functionality.
+
+\image html libdnsoverview.png
+
+\section central_structures Central structures
+
+  - \ref ldns_pkt A DNS Packet, which can contain a query, answers, and additional information.
+  - \ref ldns_rr A Resource Record, which holds a bit of information about a specific domain name.
+  - \ref ldns_rdf An RDATA field, every Resource Record contains one or more RDATA fields, depending on the type of RR. These are the 'basic types' of DNS data.
+  - \ref ldns_rr_list A list of resource records
+  - \ref ldns_zone A representation of a DNS Zone.
+
+The actual structure definitions are named \c ldns_struct_<name> which are all typedeffed to \c ldns_<name>
+
+
+A DNS Resource record looks like this:
+
+<pre>
+nlnetlabs.nl.   600     IN      MX             10    open.nlnetlabs.nl.
+ \              \       \       \              \                     /
+  owner          ttl     class   type           \        rdf[]      /
+  (rdf)     (uint32_t) (rr_class) (rr_type)
+                                                 10          := rdf[0]
+                                                 open.nlnetlabs.nl. := rdf[1]
+</pre>
+
+* Owner:
+The owner name is put in an \c ldns_rdf structure, which is a normal rdata field but always
+has the type LDNS_RDF_TYPE_DNAME.
+
+An \ref ldns_rdf structure has 3 members; the size, the type of rdata and a void *
+pointer to the data. The data is always in uncompressed wireformat.
+
+The RSH (rdata) is put in an array of rdf's (in this case 2).
+
+The entire resource record is put in a RR structure, which has
+the fields described above (under the RR):
+  - owner	(nlnetlabs.nl.)
+  - ttl		(600)
+  - class	(LDNS_RR_CLASS_IN: 'IN')
+  - type         (LDNS_RR_TYPE_MX: 'MX')
+  - rd_count	(2)
+  - rdata_fields[rd_count]
+                - rdf[0]  (10)
+                - rdf[1]  (open.nlnetlabs.nl.)
+
+* RR list structure:
+An RR list structure is simply a structure with a counter
+and an array of RR structures. Different kinds of RR's can
+be grouped together this way.
+
+* RRset structure:
+An RRset structure is an RR list structure, but its accessor
+function checks if the \c ldns_rr structures in there are: 
+ - from the same type
+ - have the same TTL
+ - have the same ownername
+
+This is the RFC definition of an RRset.
+
+* pkt structure:
+A pkt structure consists out of a header structure where 
+packet specific flags are kept, TC, RD, IP from the server which
+sent the packet, etc.
+Further more it is divided in 4 sections: question, authority, answer
+and additional.
+
+All four sections have the type RRlist that simply hold a list of RR's
+
+
+\section wire_module Wire module and central structures Interface
+
+As the WIRE module takes care of the compression/decompression
+it needs a buffer which holds all the binary DNS data.
+All functions will operate on such a buffer to extract specific
+information which is then stored in RR structures.
+
+
+\section resolver_module Resolver module and central structures Interface
+
+The resolver module always returns a pkt structure. Either with
+the answer or a SERVFAIL pkt.
+
+The exact function-call parameters have not yet been 
+decided on.
+
+Also the resolver module will need to access some of the
+to_wire and from_wire function to creates ldn_pkt's from
+the data it receives (arrow not drawn).
+
+
+\section str_module str module and central structures Interface
+
+Convert to and from strings. This module could be used
+to read in a zone file (list of RRs) and convert the text strings to
+the format used by ldns. Or the other way around.
+
+
+\section net_module Net module and resolver module interface
+
+The resolver module will get a packet and will mold it so that
+it can be sent off to a nameserver. 
+It might need to interface with the wire module (arrow not drawn).
+
+\section Net module and OS/libc interface
+OS/network calls will be used here. The Net module is the only part of 
+the library where the underlying OS matters. 
+
+\section Client program ldns interface
+Any client program will have access to
+- Wire module
+- Central structures
+- Resolver module
+- str module (arrow not drawn in the above figure)
+
+\section dnssec_module DNSSEC module
+The DNSSEC types are handled in the RR module, but the crypto
+routines are contained in this module. This module will depend
+on OpenSSL for the crypto routines.

+
+Poslib is the C++ library for applications using the Domain Name System
+that is used by all Posadis tools, including the Posadis DNS server and the
+Zoneedit and Dnsquery tools. It consists of a library for creating client
+applications using DNS, and a server library for DNS servers.

+
+From libfiredns(3):
+
+libfiredns is a library for handling asynchronous DNS
+requests.  It provides a very simple interface for sending
+requests and parsing reponses, as well as low-timeout
+blocking functions.  libfiredns functions have much lower
+timeouts than the stock functions and tend to be faster
+because they send requests to all configured system
+nameservers at the same time.

+If you have questions or comments, you can reach me at

+
+
+skadns
+
+ Skadns is Kind of an Asynchronous DNS client software.
+
+    * Kind of: it's small. Really small. But it just works.
+    * Asynchronous: all DNS operations are non-blocking.
+    * DNS client software: it's a DNS client, what you may know as a "stub resolver". To perform full DNS resolution, you will still need a full resolver like dnscache.
+
+ Similar work
+
+     * ares is an asynchronous DNS resolver library with a nice interface
+     * and more configuration options than skadns (and a very reasonable
+     * size). Use it if you find that skadns lacks configurability (you
+     * shouldn't need more than it provides, but well, you're the user).
+     * Yet it doesn't hide the DNS internals as opaquely as skadns does,
+     * giving you a bunch of fds to select() on instead of just one.
+         * adns works fine, and is small for a GNU project. Impressive. But
+	 * the interface is still too complex and much too generic - the
+	 * usual problems with GNU software.
+

+ADNS; documentation scares - is it still active
+simular aims - different ways

+   \page tutorial1_mx Tutorial 1: Querying for MX records
+   \dontinclude ldns-mx.c 
+   
+   The full source code can be found in \link examples/ldns-mx.c \endlink
+   
+   ldns-mx is a simple tool that queries your default caching forwarder for
+   the MX (Mail exchange) record of the given domain.
+
+   <pre>
+   % ldns-mx nlnetlabs.nl
+   nlnetlabs.nl.   86400   IN      MX      100 omval.tednet.nl.
+   nlnetlabs.nl.   86400   IN      MX      50 open.nlnetlabs.nl.
+   </pre>
+  
+   First of all, we need to include the correct header files, so
+   that all functions are available to us:
+  
+   \skip include
+   \until dns.h
+
+   In this case we have used a configure script to generate a config.h file
+   that does all our inclusions for us, so that it can be compiled on
+   multiple platforms. If your platform supports the include files \c
+   stdint.h and \c stdlib.h, you can include these instead of using a
+   configure script.
+
+   The first included files are prerequisites that ldns needs to function.
+   The last one, of course, includes the functions of ldns itself.
+ 
+   In our main function, we declare some variables that we are going to use:
+
+   \skipline ldns_resolver
+   \until ldns_status
+
+   - The \c ldns_resolver structure keeps a list of nameservers, and can perform queries for us
+   - An \c ldns_rdf is a basic data type of dns, the RDATA. See \ref design for a description about the building blocks of DNS.
+     In this case, \c domain will be used to store the name the user specifies when calling the program
+   - An \c ldns_pkt is a DNS packet, for instance a complete query, or an answer
+   - The \c ldns_rr_list structure contains a list of DNS Resource Records (RRs). In this case, we will store the MX records we find in the list.
+   - \c ldns_status is the basic type for status messages in ldns. Most functions will return a value of this type.
+
+   First, we parse the command line argument (checks omitted on this page, see full source code), and store it in our \c domain variable:
+   \skipline ldns_dname_new_frm_str
+
+   This function takes a string containing a domain name (like
+   "nlnetlabs.nl") and returns an \c ldns_rdf representing that name. If
+   somehow the given string can not be parsed it returns NULL.
+
+   Then, we create the resolver structure:
+   \skipline ldns_resolver_new
+
+   Most of the functions work like this, the first argument is a pointer to
+   the structure where ldns should store its results (which is also a
+   pointer). The function returns a status code indicating success
+   (\ref LDNS_STATUS_OK) or an error number. Remember that these types of
+   functions allocate memory that you should free later (using the
+   ldns_free_<type> functions).
+
+   The second argument is the filename that contains information about the
+   resolver structure that is to be created. If this argument is NULL,
+   /etc/resolv.conf is used. The syntax of the file is like that of
+   /etc/resolv.conf.
+
+
+
+   We tell the resolver to query for our domain, type MX, of class IN:
+   \skipline ldns_resolver_query
+   \until )
+
+   The last argument contains flags to influence the type of query the
+   resolver structure sends. In this case, we want the nameserver to use
+   recursion, so that we'll get the final answer. Therefore, we specify the
+   \ref LDNS_RD (Recursion Desired) flag.
+
+   This should return a packet if everything goes well.
+
+   We get all RRs of type MX from the answer packet and store them in our list:
+   \skipline ldns_pkt_rr_list_by_type
+   \until )
+   
+   If this list is not empty, we sort and print it:
+   \skipline ldns_rr_list_sort
+   \skipline ldns_rr_list_print
+
+   And finally, just to be proper, we free our allocated data:
+   \skipline free(
+   \until resolver_deep_free
+
+   For structures that can contain other ldns structures, there are two types of free() function available
+     - \c ldns_free_<type> frees only the allocated data for the structure itself.
+     - \c ldns_deep_free_<type> frees the structure, and ALL structures that
+       are nested in it. For example, of you \c deep_free an ldns_rr_list,
+       all \c ldns_rr structures that were present in the list are also
+       freed.

+   </pre>
+
+
+
+Again, let's start with including some necessary header files:
+
+\skipline include
+\until errno
+
+In this example, we are going to open a file, if that fails, we'll need errno.h to display an error message.
+
+Okay, let's declare the variables we are going to need today:
+
+\skipline filename
+\until ldns_status
+
+The only two ldns-specific types here are \c ldns_zone and \c ldns_status.
+  - \c ldns_zone is the structure that can contain a complete zone
+  - \c ldns_status again is used to check return values of ldns functions
+
+
+If we get no filename, we'll read standard input, otherwise, we'll try to
+open the given filename:
+\skipline if (argc == 0)
+\until exit(EXIT_FAILURE)
+\until }
+\until }
+
+
+With the \c FILE pointer in our hands, we visit ldns to pour it into a zone
+structure:
+\skipline ldns_zone_new_frm_fp_l
+
+There is also a \c ldns_zone_new_frm_fp, but this one also remembers the
+line number it was on, so we can use that if we encounter a parse error.
+
+Just like in \ref tutorial1_mx, the first argument is a pointer
+to the place ldns should store its creation in, and again, the return value
+is the status code.
+
+The second argument is the file pointer where our zone data should reside.
+
+The third argument, if not NULL, is a \c dname that contains the zones
+origin. It will place this dname after every name in the file that is not a
+fully qualified domain name.
+
+The fourth argument, if not 0, is the default TTL to use.
+
+Both these values can be specified in the zone file by setting \c $ORIGIN and \c $TTL.
+
+The fifth argument specifies the default class, which defaults to IN (\ref LDNS_RR_CLASS_IN).
+
+And finally, every time \c ldns_zone_new_frm_fp_l reads a line from the
+input file pointer, it will increment the value pointed to by the last
+argument with 1.
+
+
+Okay, with that, we should have a nice zone structure. Of course we need to
+check whether it has succeeded.
+
+\skipline LDNS_STATUS_OK
+\until deep_free
+
+If everything went well, we sort the zone if necessary, print it, and free it.
+
+Since \c ldns_zone contains other ldns structures, we use \c ldns_deep_free
+so that every \c ldns_rr_list, \c ldns_rr et cetera are freed too.
+
+\until line_nr);
+\until }
+
+If something went wrong, we use \c ldns_get_errorstr_by_id() to get a nice
+error string instead of just a status integer.
+
+And of course, we should play nice and close the file:
+\skipline fclose
+\until exit

+/**
+   \page tutorial3_signzone Tutorial 3: Signing a zone file
+   \dontinclude ldns-signzone.c 
+   
+   The full source code can be found in \link examples/ldns-signzone.c \endlink
+
+   Of course, we start by the usual includes. Since we need a bit more here,
+   we'll add those right away.
+
+   \skipline include
+   \until define
+
+   Let's skip the boring usage() and sanity check functions, and dive right
+   into main().
+
+   \skipline main(int argc
+   \skipline {
+
+   We'll be reading another zone file, so let's prepare some variables for that.
+
+   \skipline zone
+   \until argi
+
+   We will create a separate zone structure for the signed zone, so let's have a clear name for the original one.
+
+   \skipline zone
+   \until zone
+
+   To sign a zone, we need keys, so we need some variables to read and store it;
+
+   \skipline key
+   \until status
+
+   The \ref ldns_key structure holds (private) keys. These can be of any
+   supported algorithm type; you can put an RSA key in it, an DSA key, or an
+   HMAC key. Public keys can simply be put in an \ref ldns_rr structure with
+   type \ref LDNS_RR_TYPE_DNSKEY.
+
+   The \ref ldns_key_list type is much like the \ref ldns_rr_list, only, you
+   guessed it, for \c ldns_key entries.
+
+
+   The signed zone will be stored in a new file.
+
+   \skipline file
+   \until file
+
+   And we have some command line options for the output zone.
+
+   \skipline tm
+   \until class
+
+   \c origin is a domain name, so it can be stored in an \ref ldns_rdf
+   variable with type \ref LDNS_RDF_TYPE_DNAME.
+
+   The next part is option parsing, which is pretty straightforward using \c
+   getopt(), so we'll skip this too. U can always look to the source of the
+   file to check it out.
+
+   Okay that's it for the variables, let's get to work!
+
+   First we'll try to read in the zone that is to be signed.
+
+   \skipline fopen(zone
+   \until } else {
+
+   If the file exists and can be read, we'll let ldns mold it into a zone
+   structure:
+
+   \skipline zone_new
+
+   This creates a new (\c new) zone from (\c frm) a filepointer (\c fp),
+   while remembering the current line (\c l) in the input file (for error
+   messages).
+
+   A pointer to the zone structure to be filled is passed as the first
+   argument, like in most \c new_frm functions.
+
+   Like a lot of ldns functions, this one returns a \c ldns_status
+   indicating success or the type of failure, so let us check that.
+
+   \skipline STATUS
+   \until } else {
+
+   If everything is ok so far, we check if the zone has a SOA record and contains actual data.
+
+   \skipline orig_soa
+   \until }
+   \until }
+   \until }
+   
+   Now that we have the complete zone in our memory, we won't be needing the file anymore.
+
+   \skipline fclose
+   \until }
+   
+   If there was no origin given, we'll use the one derived from the original zone file.
+
+   \skipline origin
+   \until }
+
+   No signing party can be complete without keys to sign with, let's fetch those.
+
+   Multiple key files can be specified on the command line, by using the
+   base names of the .key/.private file pairs.
+
+   \skipline key
+   \until fopen
+
+   As you can see, we append ".private" to the name, which should result in
+   the complete file name of the private key. Later we'll also form the
+   ".key" file name, which will be directly included in the signed zone.
+
+   If the file exists, we'll read it and create a \c ldns_key from its
+   contents, much like the way we read the zone earlier.
+
+   \skipline line_nr
+   \until STATUS
+
+   If this went ok, we need to set the inception and expiration times, which
+   are set in the keys, but will eventually end up in the RRSIGs generated
+   by those keys.
+
+   \skipline expiration
+   \until }
+   \skipline inception
+   \until }
+
+   And now that we have read the private keys, we read the public keys and
+   add them to the zone.
+
+   Reading them from the files works roughly the same as reading private
+   keys, but public keys are normal Resource Records, and they can be stored
+   in general \c ldns_rr structures.
+
+   \skipline FREE
+   \until }
+   \until }
+
+   With \c push() we add them to our key list and our zone. This function
+   clones the data, so we can safely free it after that.
+
+   \skipline push
+   \until free
+
+   And if we're done, we free the allocated memory for the file name.
+
+   \until FREE
+
+   If the reading did not work, we print an error. Finally, we move on to
+   the next key in the argument list.
+
+   \skipline } else {
+   \until }
+   \until }
+   \until }
+
+   Just to be sure, we add a little check to see if we actually have any keys now.
+   
+   \skipline count
+   \until }
+
+   So, we have our zone, we have our keys, let's do some signing!
+
+   \skipline sign
+
+   Yes. That's it. We now have a completely signed zone, \c ldns_zone_sign
+   checks the keys, and uses the zone signing keys to sign the data resource
+   records. NSEC and RRSIG resource records are generated and added to the
+   new zone.
+
+   So now that we have a signed zone, all that is left is to store it somewhere.
+
+   If no explicit output file name was given, we'll just append ".signed" to
+   the original zone file name.
+
+   \skipline outputfile
+   \until }
+
+   \c ldns_zone_sign returns NULL if the signing did not work, so we must check that.
+
+   \skipline signed_zone
+   \until } else {
+   
+   Writing to a file is no different than normal printing, so we'll print to
+   the file and close it.
+
+   \skipline print
+   \until }
+
+   And of course, give an error if the signing failed.
+
+   \skipline } else {
+   \until }
+
+   Just to be nice, let's free the rest of the data we allocated, and exit
+   with the right return value.
+
+   \skipline free
+   \until }

+QUICK INSTALL GUIDE
+
+drill is a subdirectory in ldns.
+
+To compile drill you need:
+autoreconf && ./configure && make
+
+If ldns is installed in a different location, use --with-ldns=directory
+See also ./configure --help
+
+In the first case you must run drill as:
+LD_LIBRARY_PATH=../.libs ./drill <options>

+REGRESSIONS
+
+This version of drill is based on ldns and as such some things
+are slightly changed. This file documents the changes.
+
+o When tracing (-T option) we use the local resolver (as specified
+  in /etc/resolv.conf) to lookup names. This increases the speed
+  dramatically, but you obviously need to be able to reach a recursive
+  server/cache.
+  Previously drill would try to resolve the names by itself.
+
+o Printing of DSs after DNSKEY records. Because we don't parse our
+  own packets anymore, we cannot print the DS directly after the DNSKEY 
+  record. The DSs are now printed AFTER the packet.
+
+o The long options are removed.
+
+o The chase function has a different output, and will be subject to change
+  in the near future.
+ 
+o The useless (for jokes only) -I option was dropped.
+
+FIXED:
+o the argument parsing is much smarter, the order doesn't matter (much)
+  anymore

+\`configure' configures ldns 1.6.13 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]

+.SH NAME
+drill \- get (debug) information out of DNS(SEC)
+.SH SYNOPSIS
+.B drill
+[
+.IR OPTIONS
+]
+.IR name
+[
+.IR @server
+]
+[
+.IR type
+]
+[
+.IR class
+]
+
+.SH DESCRIPTION
+\fBdrill\fR is a tool to designed to get all sorts of information out of the
+DNS. It is specificly designed to be used with DNSSEC. 
+.PP
+The name \fBdrill\fR is a pun on \fBdig\fR. With \fBdrill\fR you should be able
+get even more information than with \fBdig\fR.
+.PP
+If no arguments are given class defaults to 'IN' and type to 'A'. The
+server(s) specified in /etc/resolv.conf are used to query against.
+
+.PP
+\fIname\fR
+Ask for this name.
+
+.PP
+\fI@server\fR
+Send to query to this server. If not specified use the nameservers from
+\fI/etc/resolv.conf\fR.
+
+.PP
+\fItype\fR
+Ask for this RR type. If type is not given on the command line it defaults
+to 'A'. Except when doing to reverse lookup when it defaults to 'PTR'.
+
+.PP
+\fIclass\fR
+Use this class when querying.
+
+.SH SAMPLE USAGE
+\fBdrill mx miek.nl\fR
+Show the MX records of the domain miek.nl
+
+.TP
+\fBdrill -S jelte.nlnetlabs.nl\fR
+Chase any signatures in the jelte.nlnetlab.nl domain. This option is
+only available when ldns has been compiled with openssl-support.
+
+.TP
+\fBdrill -TD www.example.com\fR
+Do a DNSSEC (-D) trace (-T) from the rootservers down to www.example.com.
+This option only works when ldns has been compiled with openssl support.
+
+.TP
+\fBdrill -s dnskey jelte.nlnetlabs.nl\fR
+Show the DNSKEY record(s) for jelte.nlnetlabs.nl. For each found DNSKEY
+record also print the DS record.
+
+.SH OPTIONS
+
+.TP
+\fB\-D
+Enable DNSSEC in the query. When querying for DNSSEC types (DNSKEY, RRSIG,
+DS and NSEC) this is \fInot\fR automaticly enabled.
+
+.TP
+\fB\-T
+Trace \fIname\fR from the root down. When using this option the @server and
+the type arguments are not used.
+
+.TP
+\fB\-S
+Chase the signature(s) of 'name' to a known key or as high up in
+the tree as possible.
+
+.TP
+\fB\-V \fIlevel\fR
+Be more verbose. Set level to 5 to see the actual query that is sent.
+
+.TP
+\fB\-Q
+Quiet mode, this overrules -V. 
+
+.TP
+\fB\-f \fIfile\fR
+Read the query from a file. The query must be dumped with -w. 
+
+.TP
+\fB\-i \fIfile\fR
+read the answer from the file instead from the network. This aids
+in debugging and can be used to check if a query on disk is valid.
+If the file contains binary data it is assumed to be a query in
+network order.
+
+.TP
+\fB\-w \fIfile\fR
+Write an answer packet to file.
+
+.TP
+\fB\-q \fIfile\fR
+Write the query packet to file.
+
+.TP
+\fB\-v
+Show drill's version.
+
+.TP
+\fB\-h
+Show a short help message.
+
+.SS QUERY OPTIONS
+
+.TP
+\fB\-4
+Stay on ip4. Only send queries to ip4 enabled nameservers.
+
+.TP
+\fB\-6
+Stay on ip6. Only send queries to ip6 enabled nameservers.
+
+.TP
+\fB\-a
+Use the resolver structure's fallback mechanism if the answer
+is truncated (TC=1). If a truncated packet is received and this
+option is set, drill will first send a new query with EDNS0 
+buffer size 4096.
+
+If the EDNS0 buffer size was already set to 512+ bytes, or the
+above retry also results in a truncated answer, the resolver
+structure will fall back to TCP.
+
+.TP
+\fB\-b \fIsize\fR
+Use size as the buffer size in the EDNS0 pseudo RR.
+
+.TP
+\fB\-c \fIfile\fR
+Use file instead of /etc/resolv.conf for nameserver configuration.
+
+.TP
+\fB\-d \fIdomain\fR
+When tracing (-T), start from this domain instead of the root.
+
+.TP
+\fB\-t
+Use TCP/IP when querying a server
+
+.TP
+\fB\-k \fIkeyfile\fR
+Use this file to read a (trusted) key from. When this options is
+given \fBdrill\fR tries to validate the current answer with this
+key. No chasing is done. When \fBdrill\fR is doing a secure trace, this
+key will be used as trust anchor. Can contain a DNSKEY or a DS record.
+
+.TP
+\fB\-o \fImnemonic\fR
+Use this option to set or unset specific header bits. A bit is
+set by using the bit mnemonic in CAPITAL letters. A bit is unset when
+the mnemonic is given in lowercase. The following mnemonics are
+understood by \fBdrill\fR:
+
+        QR, qr: set, unset QueRy (default: on)
+        AA, aa: set, unset Authoritative Answer (default: off)
+        TC, tc: set, unset TrunCated (default: off)
+        RD, rd: set, unset Recursion Desired (default: on)
+        CD, cd: set, unset Checking Disabled  (default: off)
+        RA, ra: set, unset Recursion Available  (default: off)
+        AD, ad: set, unset Authenticated Data (default: off)
+
+Thus: \fB-o CD\fR, will enable Checking Disabled, which instructs the 
+cache to not validate the answers it gives out.
+
+.TP
+\fB\-p \fIport\fR
+Use this port instead of the default of 53.
+
+.TP
+\fB\-r \fIfile\fR
+When tracing (-T), use file as a root servers hint file.
+
+.TP
+\fB\-s
+When encountering a DNSKEY print the equivalent DS also.
+
+.TP
+\fB\-u
+Use UDP when querying a server. This is the default.
+
+.TP
+\fB\-w \fIfile\fR
+write the answer to a file. The file will contain a hexadecimal dump
+of the query. This can be used in conjunction with -f.
+
+.TP
+\fB\-x
+Do a reverse loopup. The type argument is not used, it is preset to PTR.
+
+.TP
+\fB\-y \fI<name:key[:algo]>\fR
+specify named base64 tsig key, and optional an algorithm (defaults to hmac-md5.sig-alg.reg.int)
+
+.TP
+\fB\-z \fR
+don't randomize the nameserver list before sending queries.

+\`configure' configures ldns 1.6.13 to adapt to many kinds of systems.
+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE.  See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+  -h, --help              display this help and exit
+      --help=short        display options specific to this package
+      --help=recursive    display the short help of all the included packages
+  -V, --version           display version information and exit
+  -q, --quiet, --silent   do not print \`checking ...' messages
+      --cache-file=FILE   cache test results in FILE [disabled]
+  -C, --config-cache      alias for \`--cache-file=config.cache'
+  -n, --no-create         do not create output files
+      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+  --prefix=PREFIX         install architecture-independent files in PREFIX
+                          [$ac_default_prefix]
+  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
+                          [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:
+  --bindir=DIR            user executables [EPREFIX/bin]
+  --sbindir=DIR           system admin executables [EPREFIX/sbin]

+
+Some influential environment variables:
+  CC          C compiler command
+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
+              nonstandard directory <lib dir>
+  LIBS        libraries to pass to the linker, e.g. -l<library>
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+              you have headers in a nonstandard directory <include dir>
+  CPP         C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+.TH ldns-compare-zones 1 "17 Oct 2007"
+.SH NAME
+ldns-compare-zones \- read and compare two zonefiles and print differences
+.SH SYNOPSIS
+.B ldns-compare-zones
+.IR [-c]
+.IR [-i]
+.IR [-d]
+.IR [-z]
+.IR [-s]
+.IR ZONEFILE1
+.IR ZONEFILE2 
+.SH DESCRIPTION
+\fBldns-compare-zones\fR reads two DNS zone files and prints number of differences.
+.nf
+Output is formated to:
+        +NUM_INS        -NUM_DEL        ~NUM_CHG
+
+.fi
+The major comparison is based on the owner name. If an owner name is present in zonefile 1, but not in zonefile 2, the resource records with this owner name are considered deleted, and counted as NUM_DEL. If an owner name is present in zonefile 2, but not in zonefile 1, the resource records with this owner name are considered inserted, and counted as NUM_INS. If an owner name is present in both, but there is a difference in the amount or content of the records, these are considered changed, and counted as NUM_CHG.
+.SH OPTIONS
+.TP
+\fB-c\fR
+Print resource records whose owner names are in both zone files, but with different resource records. (a.k.a. changed)
+.TP
+\fB-i\fR
+Print resource records whose owner names are present only in ZONEFILE2 (a.k.a. inserted)
+.TP
+\fB-d\fR
+Print resource records whose owner names are present only in ZONEFILE1 (a.k.a. deleted)
+.TP
+\fB-a\fR
+Print all changes. Specifying this option is the same as specifying -c -i
+amd -d.
+.TP
+\fB-z\fR
+Suppress zone sorting; this option is not recommended; it can cause records
+to be incorrectly marked as changed, depending of the nature of the changes.
+.TP
+\fB-s\fR
+Do not exclude the SOA record from the comparison.  The SOA record may
+then show up as changed due to a new serial number.  Off by default since
+you may be interested to know if (other zone apex elements) have changed.
+.TP
+\fB-h\fR
+Show usage and exit
+.TP
+\fB-v\fR
+Show the version and exit

+.SH DESCRIPTION
+\fBdpa\fR is used to analyze dns packets in trace files. It has 3 main options: count, filter, and count uniques (i.e. count all different occurences).
+
+.SH OPTIONS
+.TP
+\fB-c\fR \fIexpressionlist\fR
+Count occurrences of matching expressions
+
+.TP
+\fB-f\fR \fIexpression\fR
+Filter: only process packets that match the expression
+
+.TP
+\fB-h\fR 
+Show usage
+
+.TP
+\fB-p\fR
+Show the total number of correct DNS packets, and percentage of -u and
+-c values  (of the total of matching on the -f filter. if no filter is
+given, percentages are on all correct dns packets)
+
+.TP
+\fB-of\fR \fIfile\fR
+Write all packets that match the -f flag to file, as pcap data.
+
+.TP
+\fB-ofh\fR \fIfile\fR
+Write all packets that match the -f flag to file, in hexadecimal format,
+readable by drill.
+
+.TP
+\fB-s\fR
+Show possible match names
+
+.TP
+\fB-s\fR \fImatchname\fR
+show possible match operators and values for name
+
+.TP
+\fB-sf\fR
+Only evaluate packets (in representation format) that match the -f filter.
+If no -f was given, evaluate all correct dns packets.
+
+.TP
+\fB-u\fR \fImatchnamelist\fR
+Count every occurence of every value of the matchname (for instance, count all packetsizes, see EXAMPLES in ldns-dpa(1) ).
+
+.TP
+\fB-ua\fR
+For every matchname in -u, show the average value of all matches. Behaviour for match types that do not have an integer value is undefined.
+
+.TP
+\fB-uac\fR
+For every matchname in -u, show the average number of times this value was encountered.
+
+.TP
+\fB-um\fR \fInumber\fR
+Only show the results from -u for values that occurred more than <number> times.
+
+.TP
+\fB-v\fR \fIlevel\fR
+Set verbosity to level (1-5, 5 being the highest). Mostly used for debugging.
+
+.TP
+\fB-notip\fR \fIfile\fR
+Write packets that were not recognized as IP packets to file (as pcap data).
+
+.TP
+\fB-baddns\fR \fIfile\fR
+Write dns packets that were too mangled to parse to file (as pcap data).
+
+.TP
+\fB-version\fR
+Show version and exit
+
+.SH LIST AND MATCHES
+
+A <matchnamelist> is a comma separated list of match names (use -s to see possible match names).
+A <expressionlist> is a comma separated list of expressions.
+
+An expression has the following form:
+<expr>: (<expr>)
+        <expr> | <expr>
+        <expr> & <expr>
+        <match>
+
+<match>:        <matchname> <operator> <value>
+
+<operator>:
+	=	equal to <value>
+	!=	not equal to <value>
+	>	greater than <value>
+	<	lesser than <value>
+	>=	greater than or equal to <value>
+	<=	lesser than or equal to <value>
+	~=	contains <value>
+
+See the -s option for possible matchnames, operators and values.
+
+.SH EXAMPLES
+
+.TP
+ldns-dpa -u packetsize -p test.tr
+Count all different packetsizes in test.tr and show the precentages.
+
+.TP
+ldns-dpa -f "edns=1&qr=0" -of edns.tr test.tr
+Filter out all edns enable queries in test.tr and put them in edns.tr
+
+.TP
+ldns-dpa -f edns=1 -c tc=1 -u rcode test.tr
+For all edns packets, count the number of truncated packets and all their rcodes in test.tr.
+
+.TP
+ldns-dpa -c tc=1,qr=0,qr=1,opcode=QUERY test.tr
+For all packets, count the number of truncated packets, the number of packets with qr=0, the number of packets with qr=1 and the number of queries in test.tr.
+
+.TP
+ldns-dpa -u packetsize -ua test.tr
+Show all packet sizes and the average packet size per packet.
+
+.TP
+ldns-dpa -u srcaddress -uac test.tr
+Show all packet source addresses and the average number of packets sent from this address.
+
+.TP
+sudo tcpdump -i eth0 -s 0 -U -w - port 53 | ldns-dpa -f qr=0 -sf 
+Print all query packets seen on the specified interface.

+.TH ldns-gen-zone 1 "10 June 2010"
+.SH NAME
+ldns-gen-zone \- read a zonefile and print it while adding DS records and extra RR's
+.SH SYNOPSIS
+.B ldns-gen-zone 
+.IR ZONEFILE 
+
+.SH DESCRIPTION
+
+\fBldns-gen-zone\fR reads a DNS zone file and prints it. 
+
+It is build for speed, not for a nice formatting. The output
+has one resource record per line and no pretty-printing makeup.
+
+DNSSEC data (NSEC, NSEC3, RRSIG or DNSKEY) is not stripped. You may want to
+use \fBldns-read-zone\fR for that. Existing DS records are also not stripped.
+
+The idea is to use this tool for quickly generating a representative
+artificial zonefile from a real zonefile, to use it for testing purposes.
+
+.SH OPTIONS
+.TP
+\fB-a NUM\fR
+Adds NUM extra artificial NS RRSets to the output. 
+The RRSets owner names start
+with 'xn--' in an attempt to ensure uniqueness (nl.-zone does not support
+IDN's - and this tool was written with that knowledge in mind).
+
+An artificial NS RRSet has two NS records; ns1.example.com and
+ns2.example.com.
+
+.TP
+\fB-p NUM\fR
+Add NUM% of DS RRSets to the NS RRSets (anywhere between
+1-4 DS records per RRSet).
+
+.TP
+\fB-o ORIGIN\fR
+Sets an $ORIGIN, which can be handy if the one in the zonefile
+is set to '@' for example. If there is an $ORIGIN in the zonefile,
+this option will silently be ignored.
+
+.TP
+\fB-s\fR
+This is the recommended way of processing large zones that
+are already sorted and canonicalized (ie lowercase). It skips the
+sorting and canonicalization step that is required for properly
+grouping RRSets together (before adding any DS records to them. Skipping
+this step will speed things up.
+
+It is not recommended to use this option if you want to add DS records
+to unsorted, non-canonicalized zones.
+
+.TP
+\fB-h\fR
+Show usage and exit.
+
+.TP
+\fB-v\fR
+Show version and exit.
+
+.SH EXAMPLES
+
+.TP
+\fBldns-gen-zone -a 100000 -p 10 -s ./zonefile.txt\fR
+Read a zonefile, add 100.000 artificial NS RRSets and 10% of DS records,
+print it to standard output. Don't sort (will only work well if the input
+zonefile is already sorted and canonicalized).
+
+.TP
+\fBldns-gen-zone -p 10 -s -o nl zonefile.txt | named-compilezone -s relative -i none -o zonefile_10.txt nl /dev/stdin\fR
+This creates a nicely formatted zone file with the help of \fBnamed-compilezone\fR.
+It adds 10% DS records to the .nl zone, reformats it and saves it as \fBzonefile_10.txt\fR.
+
+.SH AUTHOR
+Initially written by Marco Davids, several modifications added by Miek
+Gieben, both from SIDN.
+
+.SH REPORTING BUGS
+Report bugs to <ldns-team@nlnetlabs.nl>.
+
+.SH BUGS
+Only undiscovered ones.
+
+.SH CAVEATS
+May require a machine with a considerable amount of memory for large zone files.
+
+Fake DS records hashes are generated as digest type SHA-256 (RFC4509). Be aware not to change
+the DIGESTTYPE #define in the source code in anything else but 2 if you want
+to keep things realistic.
+
+Despite a number of efforts, this program is still not the fastest in the
+world.

+.SH NAME
+ldns-key2ds \- transform a DNSKEY RR to a DS RR
+.SH SYNOPSIS
+.B ldns-key2ds 
+.IR file
+
+.SH DESCRIPTION
+\fBldns-key2ds\fR is used to transform a public DNSKEY RR to a DS RR.
+When run it will read \fIfile\fR with a DNSKEY RR in it and
+it will create a .ds file with the DS RR in it.
+
+It prints out the basename for this file (K<name>+<alg>+<id>).
+
+By default it takes a pick of algorithm similar to the key algorithm,
+SHA1 for RSASHA1, and so on.
+
+.SH OPTIONS
+.TP
+\fB-n\fR
+Write the result DS Resource Record to stdout instead of a file
+
+.TP
+\fB-1\fR
+Use SHA1 as the hash function.
+
+.TP
+\fB-2\fR
+Use SHA256 as the hash function

+.SH NAME
+ldns-keyfetcher \- retrieve the DNSSEC DNSKEYs for a zone
+.SH SYNOPSIS
+.B ldns-keyfetcher
+[ 
+.IR OPTIONS
+] 
+.IR DOMAIN 
+
+.SH DESCRIPTION
+\fBldns-keyfetcher\fR is used to retrieve the DNSKEYs of a zone. 
+
+First it finds all authoritative nameservers of the zone by tracing it from
+the root down. All authoritative nameservers are then queried (using TCP)
+for the DNSKEY RRset of the zone apex. If the results are all the same,
+the key resource record set is printed.
+
+
+.SH OPTIONS
+\fB-4\fR \fI\fR
+Only use IPv4
+
+\fB-6\fR \fI\fR
+Only use IPv6
+
+\fB-h\fR \fI\fR
+Show a help text and exit
+
+\fB-i\fR
+Insecurer mode; there will only be one query for the DNSKEYS. There will not
+be crosschecking of all authoritative nameservers.
+
+\fB-v\fR \fIverbosity\fR
+
+Set the verbosity level. The following levels are available:
+
+ 0: default, only print the DNSKEY RRset found, or an error on failure.
+ 1: Show the nameservers that are queried
+ 2: Show more info on what is checked
+ 3: Show the intermediate results (authority and dnskey rrsets)
+ 4: Print the answer packets that are returned
+
+\fB-r\fR \fIfile\fR
+
+Use file as the root hints file, should contain A records in presentation
+format. The default is /etc/named.root. You can get this file from
+http://www.internic.net/zones/named.root.
+
+\fB-s\fR \fI\fR
+Don't print the keys to stdout, but store them in files.
+
+The filenames will be of the format K<file>.+<alg>.+<keytag>.key

+.SH NAME
+ldns-keygen \- generate a DNSSEC key pair
+.SH SYNOPSIS
+.B ldns-keygen 
+[
+.IR OPTION
+]
+.IR DOMAIN 
+
+.SH DESCRIPTION
+\fBldns-keygen\fR is used to generate a private/public keypair. When run, it
+will create 3 files; a .key file with the public DNSKEY, a .private
+file with the private keydata and a .ds with the DS record of the
+DNSKEY record.
+
+It prints out the basename for these files: K<name>+<alg>+<id>
+
+.SH OPTIONS
+.TP
+\fB-a \fI<algorithm>\fR 
+Create a key with this algorithm. Specifying 'list' here gives a list of supported algorithms.
+Several alias names are also accepted (from older versions and other software),
+the list gives names from the RFC.  Also the plain algo number is accepted.
+
+.TP
+\fB-b \fI<bits>\fR 
+Use this many bits for the key length.
+
+.TP
+\fB-k\fR 
+When given, generate a key signing key. This just sets the flag field to
+257 instead of 256 in the DNSKEY RR in the .key file.
+
+.TP
+\fB-r \fIdevice\fR
+Make ldns-keygen use this file to seed the random generator with. This will
+default to /dev/random.
+
+.TP
+\fB-v\fR
+Show the version and exit
+

+
+.SH DESCRIPTION
+
+\fBldns-notify\fR sends a NOTIFY message to DNS servers. This tells them
+that an updated zone is available at the master servers. It can perform
+TSIG signatures and it can add a SOA serial number of the updated zone.
+If a server already has that serial number it will disregard the message.
+
+.SH OPTIONS
+.TP
+\fB-z zone\fR
+The zone that is updated.
+
+.TP
+\fB-h\fR
+Show usage and exit
+
+.TP
+\fB-v\fR
+Show the version and exit
+
+.TP
+\fB-s serial\fR
+Append a SOA record indicating the serial number of the updated zone.
+
+.TP
+\fB-p port\fR
+Use port as destination port (default the DNS port 53) for the UDP packets.
+
+.TP
+\fB-y key:data\fR
+Use the given TSIG key and base64-data to sign the NOTIFY. Uses the
+hmac-md5 algorithm.
+
+.TP
+\fB-d\fR
+Print verbose debug information. The query that is sent and the query
+that is received.
+
+.TP
+\fB-r num\fR
+Specify the maximum number of retries before notify gives up trying to
+send the UDP packet.
+
+.SH EXIT CODE
+The program exits with a 0 exit code if all servers replied an 
+acknowledgement to the notify message, and a failure exit code otherwise. 
+
+.SH AUTHOR
+Written by the ldns team as an example for ldns usage.
+
+.SH REPORTING BUGS
+Report bugs to <ldns-team@nlnetlabs.nl>.

+.SH NAME
+ldns-read-zone \- read a zonefile and print it
+.SH SYNOPSIS
+.B ldns-read-zone 
+.IR ZONEFILE 
+
+.SH DESCRIPTION
+
+\fBldns-read-zone\fR reads a DNS zone file and prints it. The output has 1
+resource record per line, and no pretty-printing makeup.
+
+.SH OPTIONS
+.TP
+\fB-c\fR
+Canonicalize all resource records in the zone before printing
+
+.TP
+\fB-d\fR
+Only print DNSSEC data from the zone. This option skips every record
+that is not of type NSEC, NSEC3, RRSIG or DNSKEY. DS records are not
+printed.
+
+.TP
+\fB-h\fR
+Show usage and exit
+
+.TP
+\fB-n\fR
+Do not print the SOA record
+
+.TP
+\fB-s\fR
+Strip DNSSEC data from the zone. This option skips every record
+that is of type NSEC, NSEC3, RRSIG or DNSKEY. DS records are still
+printed.
+
+.TP
+\fB-S\fR \fI[[+|0]number | YYYYMMDDxx | unixtime ]\fR
+Set serial number to the given \fInumber\fR, or when preceded by a sign,
+offset the exisiting number with it. When giving the literal strings 
+\fIYYYYMMDDxx\fR or \fIunixtime\fR, the serial number is tried to be reset
+in datecounter or in unixtime format respectively. Though is the updated serial
+number is smaller than the original one, the original one is simply
+increased by one.
+
+When updating a serial number, records of type NSEC, NSEC3, RRSIG and DNSKEY
+will be skipped when printing the zone.
+
+
+.TP
+\fB-v\fR
+Show the version and exit
+
+.TP
+\fB-z\fR
+Sort the zone before printing (this implies -c)

+.SH NAME
+ldns-signzone \- sign a zonefile with DNSSEC data
+.SH SYNOPSIS
+.B ldns-signzone 
+[
+.IR OPTIONS
+]
+.IR ZONEFILE 
+.IR
+KEY 
+[KEY 
+[KEY] ...
+]
+
+.SH DESCRIPTION
+
+\fBldns-signzone\fR is used to generate a DNSSEC signed zone. When run it
+will create a new zonefile that contains RRSIG and NSEC resource records, as
+specified in RFC 4033, RFC 4034 and RFC 4035.
+
+Keys must be specified by their base name (i.e. without .private). If
+the DNSKEY that belongs to the key in the .private file is not present
+in the zone, it will be read from the file <base name>.key. If that
+file does not exist, the DNSKEY value will be generated from the
+private key.
+
+Multiple keys can be specified, Key Signing Keys are used as such when
+they are either already present in the zone, or specified in a .key
+file, and have the KSK bit set.
+
+.SH OPTIONS
+.TP
+\fB-b\fR
+Augments the zone and the RR's with extra comment texts for a more readable
+layout, easier to debug. DS records will have a bubblebabble version of
+the data in the comment text, NSEC3 records will have the original NSEC3
+in the comment text.
+
+Without this option, only DNSKEY RR's will have their Key Tag annotated in
+the comment text.
+
+.TP
+\fB-d\fR
+Normally, if the DNSKEY RR for a key that is used to sign the zone is
+not found in the zone file, it will be read from .key, or derived from
+the private key (in that order). This option turns that feature off,
+so that only the signatures are added to the zone.
+
+.TP
+\fB-e\fR \fIdate\fR
+Set expiration date of the signatures to this date, the format can be
+YYYYMMDD[hhmmss], or a timestamp.
+
+.TP
+\fB-f\fR \fIfile\fR
+Use this file to store the signed zone in (default <originalfile>.signed)
+
+.TP
+\fB-i\fR \fIdate\fR
+Set inception date of the signatures to this date, the format can be
+YYYYMMDD[hhmmss], or a timestamp.
+
+.TP
+\fB-o\fR \fIorigin\fR
+Use this as the origin of the zone
+
+.TP
+\fB-v\fR
+Print the version and exit
+
+.TP
+\fB-A\fR
+Sign the DNSKEY record with all keys.  By default it is signed with a
+minimal number of keys, to keep the response size for the DNSKEY query
+small, and only the SEP keys that are passed are used.  If there are no
+SEP keys, the DNSKEY RRset is signed with the non\-SEP keys.  This option
+turns off the default and all keys are used to sign the DNSKEY RRset.
+
+.TP
+\fB-E\fR \fIname\fR
+Use the EVP cryptographic engine with the given name for signing. This
+can have some extra options; see ENGINE OPTIONS for more information.
+
+.TP
+\fB-k\fR \fIid,int\fR
+Use the key with the given id as the signing key for algorithm int as
+a Zone signing key. This option is used when you use an OpenSSL
+engine, see ENGINE OPTIONS for more information.
+
+.TP
+\fB-K\fR \fIid,int\fR
+
+Use the key with the given id as the signing key for algorithm int as
+a Key signing key. This options is used when you use an OpenSSL engine,
+see ENGINE OPTIONS for more information.
+
+.TP
+\fB-n\fR
+Use NSEC3 instead of NSEC.
+
+.TP
+If you use NSEC3, you can specify the following extra options:
+
+.TP
+\fB-a\fR \fIalgorithm\fR
+Algorithm used to create the hashed NSEC3 owner names
+
+.TP
+\fB-p\fR
+Opt-out. All NSEC3 records in the zone will have the Opt-out flag set. After signing, you can add insecure delegations to the signed zone.
+
+.TP
+\fB-s\fR \fIstring\fR
+Salt
+
+.TP
+\fB-t\fR \fInumber\fR
+Number of hash iterations
+
+.SH ENGINE OPTIONS
+You can modify the possible engines, if supported, by setting an
+OpenSSL configuration file. This is done through the environment
+variable OPENSSL_CONF. If you use -E with a non-existent engine name,
+ldns-signzone will print a list of engines supported by your
+configuration.
+
+The key options (-k and -K) work as follows; you specify a key id, and a DNSSEC algorithm number (for instance, 5 for RSASHA1). The key id can be any of the following:
+
+    <id>
+    <slot>:<id>
+    id_<id>
+    slot_<slot>-id_<id>
+    label_<label>
+    slot_<slot>-label_<label>
+
+Where '<id>' is the PKCS #11 key identifier in hexadecimal
+notation, '<label>' is the PKCS #11 human-readable label, and '<slot>'
+is the slot number where the token is present.
+
+If not already present, a DNSKEY RR is generated from the key
+data, and added to the zone.
+
+.SH EXAMPLES
+
+.TP
+ldns-signzone nlnetlabs.nl Knlnetlabs.nl.+005+12273
+Sign the zone in the file 'nlnetlabs.nl' with the key in the
+files 'Knlnetlabs.nl.+005+12273.private'. If the DNSKEY is not present
+in the zone, use the key in the
+file 'Knlnetlabs.nl.+005+12273.key'. If that is not present, generate
+one with default values from 'Knlnetlabs.nl.+005+12273.private'.

+.TH ldns-test-edns 1 "14 Dec 2010"
+.SH NAME
+ldns-test-edns \- test if dns cache supports EDNS and DNSSEC.
+.SH SYNOPSIS
+.B ldns-test-edns
+[
+.IR -i
+]
+{
+.IR ip 
+}
+.SH DESCRIPTION
+\fBldns-test-edns\fR tests a DNS cache and checks if it supports EDNS0 and
+DNSSEC types so that it can be used as a dnssec-enabled DNS cache.  It sends
+two queries to the cache, one for the root key and one for a DS record.
+These must succeed, the answer must have EDNS, that type and signatures.
+.PP
+If the IP address is good for DNSSEC, it is printed with 'OK'.  Otherwise
+short description is given of the failure.
+If OK is given, the cache should be good to use as a cache for a local
+configured DNSSEC validator.
+.PP
+The tool assumes the root is signed and Sweden is signed.
+Also, the queries are sent with the CD flag, the tool does not check that the
+results are validated, but that they \fBcan\fR be validated.
+.SH OPTIONS
+\fB-i\fR option enables a mode where the working IP addresses are printed
+after another, with no other explanations, and if none work or no IP addresses
+are on the input, 'off' is printed.
+.PP
+\fBldns-test-edns\fR takes one or more IP addresses, it checks them in turn.
+IPv4 and IPv6 addresses can be given.  The exit value is for the last checked
+IP address: 0 is OK, 1 is failure, 2 is some sort of network failure.

+.TH ldns-testns 1 "14 Dec 2006"
+.SH NAME
+ldns-testns \- simple fake nameserver tool
+.SH SYNOPSYS
+.B ldns-testns
+[
+.IR OPTION
+]
+.IR datafile
+
+.SH DESCRIPTION
+\fBldns-testns\fR can be used to provide answers to DNS queries for
+testing.  The answers are premade, and can be tailored to testing
+needs. The answers can be wildly invalid or unparseable.
+
+This program is a debugging aid. It is not efficient, especially
+with a long config file, but it can give any reply to any query.
+This can help the developer pre-script replies for queries.
+
+It listens to IP4 UDP and TCP by default.
+You can specify a packet RR by RR with header flags to return.
+
+ldns-testns is not meant for production use.
+
+.SH OPTIONS
+.TP
+\fB-r\fR
+Listens to a random port. The port number is printed to stdout.
+
+.TP
+\fB-p\fR \fIport\fR
+Listens to the specified port.
+
+.TP
+\fB-f\fR \fInum\fR
+Forks this number of additional instances that serve the same ports and
+same datafile. They do not exit; printed is 'forked pid: <num>' and you
+have to kill them yourself.
+
+.TP
+\fB-v\fR
+Outputs more debug information. It is possible to give this option multiple 
+times to increase verbosity level.
+
+.TP
+\fB-6\fR
+Bind to IP6 address instead of IP4. Use together with -p. 
+
+.TP
+\fBdatafile\fR
+The data file is read on start up. It contains queries and the packets 
+that should be sent in answer to those queries. The data file format is
+explained below.
+
+.SH DATA FILE FORMAT
+The data file format has ';' to denote comment. A number of entries
+are processed first to last. The first matching entry is used to answer
+the query with. This is a line based format. DNS resource records
+are entered in zone-file format.
+
+You can use $ORIGIN and $TTL directives. Zone file '(' and ')' to span
+multiple lines are not allowed.
+
+$ORIGIN origin
+$TTL default_ttl
+
+ENTRY_BEGIN
+
+; first give MATCH lines, that say what queries are matched
+; by this entry.
+; 'opcode' makes the query match the opcode from the reply
+; if you leave it out, any opcode matches this entry.
+; 'qtype' makes the query match the qtype from the reply
+; 'qname' makes the query match the qname from the reply
+; 'serial=1023' makes the query match if ixfr serial is 1023.
+

+.TH ldns-verifyzone 1 "27 May 2008"
+.SH NAME
+ldns-verify-zone \- read a DNSSEC signed zone and verify it.
+.SH SYNOPSIS
+.B ldns-verify-zone 
+.IR ZONEFILE 
+
+.SH DESCRIPTION
+
+\fBldns-verify-zone\fR reads a DNS zone file and verifies it. 
+
+RRSIG resource records are checked against the DNSKEY set at the zone apex.
+
+Each name is checked for an NSEC(3), if appropriate.
+
+.SH OPTIONS
+.TP
+\fB-h\fR
+Show usage and exit
+
+.TP
+\fB-a\fR
+Apex only, check only the zone apex
+
+.TP
+\fB-e\fR \fIperiod\fR
+Signatures may not expire within this period.
+Default no period is used.
+
+.TP
+\fB-i\fR \fIperiod\fR
+Signatures must have been valid at least this long.
+Default signatures should just be valid now.
+
+.TP
+\fB-k\fR \fIfile\fR
+A file that contains a trusted DNSKEY or DS rr.
+This option may be given more than once.
+
+.TP
+\fB-p\fR \fI[0-100]\fR
+Only check this percentage of the zone.
+Which names to check is determined randomly.
+Defaults to 100.
+
+.TP
+\fB-S\fR
+Chase signature(s) to a known key.
+The network may be accessed to validate the zone's DNSKEYs. (implies -k)
+
+.TP
+\fB-t\fR \fIYYYYMMDDhhmmss | [+|-]offset\fR
+Set the validation time either by an absolute time value or as an offset in seconds from the current time.
+
+.TP
+\fB-v\fR
+Show the version and exit
+
+.TP
+\fB-V\fR \fInumber\fR
+Set the verbosity level (default 3):
+
+ 0: Be silent
+ 1: Print result, and any errors
+ 2: Same as 1 for now
+ 3: Print result, any errors, and the names that are
+    being checked
+ 4: Same as 3 for now
+ 5: Print the zone after it has been read, the result, 
+    any errors, and the names that are being checked
+
+.LP
+\fIperiod\fRs are given in ISO 8601 duration format:
+.RS
+P[n]Y[n]M[n]DT[n]H[n]M[n]S
+.RE
+.LP
+If no file is given standard input is read.

+.TH ldns-walk 1 "21 Nov 2005"
+.SH NAME
+ldns-walk \- Retrieve the contents of a DNSSEC signed zone
+.SH SYNOPSIS
+.B ldns-walk
+[
+.IR OPTION
+]
+.IR ZONE 
+
+.SH DESCRIPTION
+
+\fBldns-walk\fR is used to retrieve the contents of a DNSSEC signed zone.
+It does this through NSEC-walking (following the chain of NSEC records)
+and 'guessing' the next non-existent owner name for each NSEC.
+
+Note that it might get stuck on some wildcard records when used through a
+caching forwarder. This problem can be circumvented by querying the
+authoritative nameserver directly (with the @ argument).
+
+Of course the nameserver that is used must be DNSSEC-aware.
+
+.SH OPTIONS
+.TP
+\fB-f\fR
+Do a 'full' zone walk; by default, ldns-walk will only show the names, and types present at those names. If this option is given, all resource records will be printed.
+
+.TP
+\fB-s\fR \fIname\fR
+Start the walk with this owner name. Useful when continuing the walk for a
+large zone.
+
+.TP
+\fB@\fR \fInameserver\fR
+Send the queries to this nameserver.
+
+.SH BUGS
+The full zone walk function is not complete yet, it does not correctly print delegation records
+

+\section introduction Introduction
+
+The goal of ldns is to simplify DNS programming, it supports recent RFCs
+like the DNSSEC documents, and allow developers to easily create software
+conforming to current RFCs, and experimental software for current Internet
+drafts. A secondary benefit of using ldns is speed, because ldns is written
+in C, and although it is not optimized for performance, it should be a lot
+faster than Perl.
+
+The first main tool to use ldns is Drill, from which part of the library was
+derived. From version 1.0.0 on, drill is included in the ldns release
+and will not be distributed seperately anymore. The library also includes some
+other examples and tools to show how it can be used. These can be found in the
+examples/ directory in the tarball.
+
+ldns depends on OpenSSL for it's cryptographic functions.
+Feature list
+
+  - Transparent IPv4 and IPv6 support (overridable if necessary),
+  - TSIG support,
+  - DNSSEC support; signing and verification,
+  - small size,
+  - online documentation as well as manual pages. 
+
+If you want to send us patches please use the code from subversion (trunk). 
+
+\section using_ldns Using ldns
+
+Almost all interaction between an application and ldns goes through the ldns
+data structures (\ref ldns_rr, \ref ldns_pkt, etc.). These are input or
+output to the functions of ldns. For example, \ref ldns_zone_new_frm_fp
+reads a zone from a \c FILE pointer, and returns an \ref ldns_zone
+structure.
+
+
+Let's use Drill as an example. Drill is a tool much like dig, whose most
+basic function is to send 1 query to a nameserver and print the response.
+
+To be able to do this, drill uses the resolver module of ldns, which acts as
+a stub resolver. The resolver module uses the net module to actually send
+the query that drill requested. It then uses the wire2host module to
+translate the response and place it in ldns' internal structures. These are
+passed back to drill, which then uses the host2str module to print the
+response in presentation format.
+
+\section gettingstarted Getting Started
+
+See the \ref design page for a very high level description of the design
+choices made for ldns. 
+
+For an overview of the functions and types ldns provides, you can check out
+the \ref ldns ldns header file descriptions.
+
+If you want to see some libdns action, you can read our tutorials:
+  - \ref tutorial1_mx
+  - \ref tutorial2_zone
+  - \ref tutorial3_signzone
+
+Or you can just use the menu above to browse through the API docs.

+
+# This file describes the settings to be used by the documentation system
+# doxygen (www.doxygen.org) for a project.
+#
+# All text after a hash (#) is considered a comment and will be ignored.
+# The format is:
+#       TAG = value [value, ...]
+# For lists items can also be appended using:
+#       TAG += value [value, ...]
+# Values that contain spaces should be placed between quotes (" ").
+
+#---------------------------------------------------------------------------
+# Project related configuration options
+#---------------------------------------------------------------------------
+
+# This tag specifies the encoding used for all characters in the config file
+# that follow. The default is UTF-8 which is also the encoding used for all
+# text before the first occurrence of this tag. Doxygen uses libiconv (or the
+# iconv built into libc) for the transcoding. See
+# http://www.gnu.org/software/libiconv for the list of possible encodings.
+
+DOXYFILE_ENCODING      = UTF-8
+
+# The PROJECT_NAME tag is a single word (or a sequence of words surrounded
+# by quotes) that should identify the project.
+

+

+# This could be handy for archiving the generated documentation or
+# if some version control system is used.

+# With the PROJECT_LOGO tag one can specify an logo or icon that is
+# included in the documentation. The maximum height of the logo should not
+# exceed 55 pixels and the maximum width should not exceed 200 pixels.

+

+
+# The OUTPUT_DIRECTORY tag is used to specify the (relative or absolute)
+# base path where the generated documentation will be put.

+# where doxygen was started. If left blank the current directory will be used.

+# 4096 sub-directories (in 2 levels) under the output directory of each output
+# format and will distribute the generated files over these directories.

+# source files, where putting all generated files in the same directory would
+# otherwise cause performance problems for the file system.

+
+# The OUTPUT_LANGUAGE tag is used to specify the language in which all
+# documentation generated by doxygen is written. Doxygen will use this
+# information to generate all constant output in the proper language.
+# The default language is English, other supported languages are:
+# Afrikaans, Arabic, Brazilian, Catalan, Chinese, Chinese-Traditional,
+# Croatian, Czech, Danish, Dutch, Esperanto, Farsi, Finnish, French, German,
+# Greek, Hungarian, Italian, Japanese, Japanese-en (Japanese with English
