The libzfs_core interface will be committed, + * therefore consumers can compile against it and be confident that + * their code will continue to work on future releases of this code. + * Currently, the interface is Evolving (not Committed), but we intend + * to commit to it once it is more complete and we determine that it + * meets the needs of all consumers. + * + * - Programatic Error Handling. libzfs_core communicates errors with + * defined error numbers, and doesn't print anything to stdout/stderr. + * + * - Thin Layer. libzfs_core is a thin layer, marshaling arguments + * to/from the kernel ioctls. There is generally a 1:1 correspondence + * between libzfs_core functions and ioctls to /dev/zfs. + * + * - Clear Atomicity. Because libzfs_core functions are generally 1:1 + * with kernel ioctls, and kernel ioctls are general atomic, each + * libzfs_core function is atomic. For example, creating multiple + * snapshots with a single call to lzc_snapshot() is atomic -- it + * can't fail with only some of the requested snapshots created, even + * in the event of power loss or system crash. + * + * - Continued libzfs Support. Some higher-level operations (e.g. + * support for "zfs send -R") are too complicated to fit the scope of + * libzfs_core. This functionality will continue to live in libzfs. + * Where appropriate, libzfs will use the underlying atomic operations + * of libzfs_core. For example, libzfs may implement "zfs send -R | + * zfs receive" by using individual "send one snapshot", rename, + * destroy, and "receive one snapshot" operations in libzfs_core. + * /sbin/zfs and /zbin/zpool will link with both libzfs and + * libzfs_core. Other consumers should aim to use only libzfs_core, + * since that will be the supported, stable interface going forwards. + */ + +#define _IN_LIBZFS_CORE_ + +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include "libzfs_core_compat.h" +#include "libzfs_compat.h" + +#ifdef __FreeBSD__ +extern int zfs_ioctl_version; +#endif + +static int g_fd; +static pthread_mutex_t g_lock = PTHREAD_MUTEX_INITIALIZER; +static int g_refcount; + +int +libzfs_core_init(void) +{ + (void) pthread_mutex_lock(&g_lock); + if (g_refcount == 0) { + g_fd = open("/dev/zfs", O_RDWR); + if (g_fd < 0) { + (void) pthread_mutex_unlock(&g_lock); + return (errno); + } + } + g_refcount++; + (void) pthread_mutex_unlock(&g_lock); + + return (0); +} + +void +libzfs_core_fini(void) +{ + (void) pthread_mutex_lock(&g_lock); + ASSERT3S(g_refcount, >, 0); + g_refcount--; + if (g_refcount == 0) + (void) close(g_fd); + (void) pthread_mutex_unlock(&g_lock); +} + +static int +lzc_ioctl(zfs_ioc_t ioc, const char *name, + nvlist_t *source, nvlist_t **resultp) +{ + zfs_cmd_t zc = { 0 }; + int error = 0; + char *packed; +#ifdef __FreeBSD__ + nvlist_t *oldsource; +#endif + size_t size; + + ASSERT3S(g_refcount, >, 0); + + (void) strlcpy(zc.zc_name, name, sizeof (zc.zc_name)); + +#ifdef __FreeBSD__ + if (zfs_ioctl_version == ZFS_IOCVER_UNDEF) + zfs_ioctl_version = get_zfs_ioctl_version(); + + if (zfs_ioctl_version < ZFS_IOCVER_LZC) { + oldsource = source; + error = lzc_compat_pre(&zc, &ioc, &source); + if (error) + return (error); + } +#endif + + packed = fnvlist_pack(source, &size); + zc.zc_nvlist_src = (uint64_t)(uintptr_t)packed; + zc.zc_nvlist_src_size = size; + + if (resultp != NULL) { + *resultp = NULL; + zc.zc_nvlist_dst_size = MAX(size * 2, 128 * 1024); + zc.zc_nvlist_dst = (uint64_t)(uintptr_t) + malloc(zc.zc_nvlist_dst_size); +#ifdef illumos + if (zc.zc_nvlist_dst == NULL) { +#else + if (zc.zc_nvlist_dst == 0) { +#endif + error = ENOMEM; + goto out; + } + } + + while (ioctl(g_fd, ioc, &zc) != 0) { + if (errno == ENOMEM && resultp != NULL) { + free((void *)(uintptr_t)zc.zc_nvlist_dst); + zc.zc_nvlist_dst_size *= 2; + zc.zc_nvlist_dst = (uint64_t)(uintptr_t) + malloc(zc.zc_nvlist_dst_size); +#ifdef illumos + if (zc.zc_nvlist_dst == NULL) { +#else + if (zc.zc_nvlist_dst == 0) { +#endif + error = ENOMEM; + goto out; + } + } else { + error = errno; + break; + } + } + +#ifdef __FreeBSD__ + if (zfs_ioctl_version < ZFS_IOCVER_LZC) + lzc_compat_post(&zc, ioc); +#endif + if (zc.zc_nvlist_dst_filled) { + *resultp = fnvlist_unpack((void *)(uintptr_t)zc.zc_nvlist_dst, + zc.zc_nvlist_dst_size); + } +#ifdef __FreeBSD__ + if (zfs_ioctl_version < ZFS_IOCVER_LZC) + lzc_compat_outnvl(&zc, ioc, resultp); +#endif +out: +#ifdef __FreeBSD__ + if (zfs_ioctl_version < ZFS_IOCVER_LZC) { + if (source != oldsource) + nvlist_free(source); + source = oldsource; + } +#endif + fnvlist_pack_free(packed, size); + free((void *)(uintptr_t)zc.zc_nvlist_dst); + return (error); +} + +int +lzc_create(const char *fsname, dmu_objset_type_t type, nvlist_t *props) +{ + int error; + nvlist_t *args = fnvlist_alloc(); + fnvlist_add_int32(args, "type", type); + if (props != NULL) + fnvlist_add_nvlist(args, "props", props); + error = lzc_ioctl(ZFS_IOC_CREATE, fsname, args, NULL); + nvlist_free(args); + return (error); +} + +int +lzc_clone(const char *fsname, const char *origin, + nvlist_t *props) +{ + int error; + nvlist_t *args = fnvlist_alloc(); + fnvlist_add_string(args, "origin", origin); + if (props != NULL) + fnvlist_add_nvlist(args, "props", props); + error = lzc_ioctl(ZFS_IOC_CLONE, fsname, args, NULL); + nvlist_free(args); + return (error); +} + +/* + * Creates snapshots. + * + * The keys in the snaps nvlist are the snapshots to be created. + * They must all be in the same pool. + * + * The props nvlist is properties to set.

+	  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 #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.

+	  Steve Reid, and Aaron D. Gifford for the code.
+	* Added reading/writing support for the SPF Resource Record
+	* Base32 functions are now exported
+	Bugfixes:

+
+	API addition:

+	  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

+	* 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 
+	* 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 
     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 HÃ¥kan Olsson
+	* Added UPDATE support (Jakob Schlyter and HÃ¥kan 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)
+  - OpenSSL >= 0.9.7f for DANE support
+  - OpenSSL >= 1.0.0  for ECDSA and GOST support
+- 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-
+3. ./configure --with-examples --with-drill
+   (optionally compile python bindings too with: --with-pyldns)
+4. make
+5. make install
+
+
+* 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!

+
+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.

+
+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/.

+# 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
+#     AX_SWIG_PYTHON

+# 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

+             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.

+   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.

+\`configure' configures ldns 1.6.16 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]

+  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
+  --libdir=DIR            object code libraries [EPREFIX/lib]
+  --includedir=DIR        C header files [PREFIX/include]
+  --oldincludedir=DIR     C header files for non-gcc [/usr/include]
+  --datarootdir=DIR       read-only arch.-independent data root [PREFIX/share]
+  --datadir=DIR           read-only architecture-independent data [DATAROOTDIR]

+# 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.

+# This is what autoupdate's m4 run will expand.  It fires
+# the warning (with _au_warn_XXX), outputs it into the
+# updated configure.ac (with AC_DIAGNOSE), and then outputs
+# the replacement expansion.
+
+
+# This is an auxiliary macro that is also run when
+# autoupdate runs m4.  It simply calls m4_warning, but
+# we need a wrapper so that each warning is emitted only
+# once.  We break the quoting in m4_warning's argument in
+# order to expand this macro's arguments, not AU_DEFUN's.
+
+
+# Finally, this is the expansion that is picked up by
+# autoconf.  It tells the user to run autoupdate, and
+# then outputs the replacement expansion.  We do not care
+# about autoupdate's warning because that contains
+# information on what to do *after* running autoupdate.

+# 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
+#     AX_SWIG_PYTHON

+--------- Drill now is a subdirectory in ldns. To make life easier 
+--------- we are using ldns' version numbering for drill from now on. 
+--------- Sadly this means we GO BACKWARDS in the versions
+--------- This ChangeLog will not be updated anymore - all changes are
+--------- documented in ldns' ChangeLog
+
+1.0-pre3: to be released: drill-team
+	* Secure tracing works
+	* Added section about DNSSEC in the manual page
+	* Allow the class information to be given to do_chase()
+	* Lint fixes for the code
+	* Bugzilla was setup for drill
+	* Bug #97 (drill); -S crash was fixed
+	* Add -Q (quiet) flag was added. This supresses output from drill.
+
+1.0-pre2: 20 Jun 2005: drill-team
+	* Second prerelease
+	* Bugs where fix in the chasing functionality
+
+1.0-pre1: 1 Jun 2005: drill-team
+	* First drill release based on ldns
+	* drill's core code is not much more simple, as
+	  all the difficult stuff is moved to ldns.
+	* Much saner argument parsing
+
+---------- Above Newer drill based on ldns              --------------
+---------- Below Older drill with it's own DNS handling --------------
+
+0.9.2: Feb 3 2005: drill-team
+	* Added two more options (borrowed from dig)
+	  --rd, don't set the RD bit in queries
+	  --fail, don't query the next nameserver on SERVFAIL
+	* Fixed handling of obscure data types
+	* Handle classes other the 'IN' when making a query
+
+	* For people using FreeBSD: drill is now in the ports
+	  (Thanks to Jaap Akkerhuis)
+
+0.9.1: Jan 5 2005: drill-team
+	* Makefile tweaks
+	* drill ns . works
+	* re-check the root in when tracing
+	* added handling for some lesser known types (including WKS)
+
+0.9: Dec 6 2004: drill-team
+	* big configure.ac and Makefile.in updates (made more general)
+	* escapes in names argument and txt and dname data
+	* gcc 2(.95) support
+	* packet wire data is now checked for dangerous elements (like
+	  looping compression etc)
+	* (Multiple) Octal char representation
+	* Responses can be saved to file
+	* 'Answers' can be read from file instead of server
+	* Lots and lots of bugfixes and improvements
+
+0.8.1: Oct 27 2004: Miek
+	* configure.ac updates
+	* secure resolving updates (still doesn't work)
+	* printing additions
+	  - CERT RR supported
+	  - LOC RR support
+	* All non supported RRs are handled as unknown
+	* If no namservers found in /etc/resolv.conf 
+	  default to 127.0.0.1
+	* Various bugs fixed
+	  - Close sockets after using them
+	  - Some memory leaks were plugged
+
+0.8: Oct 26 2004: Miek
+	* Lots of features added. Drill is almost feature complete
+	* Unknown RR's are supported
+	* Numerous smaller updates in documentation
+	* Numerous code cleanups
+	* Dig is no longer needed to build drill
+
+0.7: Oct 21 2004: Miek
+	* reworked interal code
+	* DNSSEC is working, except the secure resolving
+	* build updates
+	* more sane options parsing
+	* more sane argument handling
+
+0.6-alpha: Oct 2004: Jelte
+	* No log
+
+0.5-alpha: Sept 22 2004: Miek
+	* most of the DNS stuff is working
+	* moved to configure
+	* tested on Linux/FreeBSD
+	* fully IPV6 capable
+	* new DNSSEC types supported
+	* DNSSEC somewhat working
+	* gcc => 3 is needed for building
+
+0.4-alpha: Sept 9 2004: Miek 
+	* moved to autoconf for building
+	* lots of various updates
+	* really a workable program now
+
+0.3-alpha: Sept 6 2004: Miek 
+	* IPv6 support
+	* automatic secure resolving
+	* --trace updates
+	* --chase updates
+	* more checks

+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

+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 1.6.16 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]

+  --localstatedir=DIR     modifiable single-machine data [PREFIX/var]
+  --libdir=DIR            object code libraries [EPREFIX/lib]
+  --includedir=DIR        C header files [PREFIX/include]
+  --oldincludedir=DIR     C header files for non-gcc [/usr/include]

+  CFLAGS      C compiler flags
+  LDFLAGS     linker flags, e.g. -L if you have libraries in a
+              nonstandard directory 
+  LIBS        libraries to pass to the linker, e.g. -l
+  CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I if
+              you have headers in a nonstandard directory 
+  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.

+.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.
+
+Alternatively, when DNSSEC enabled tracing (\fB-TD\fR) or signature
+chasing (\fB-S\fR), if \fB-k\fR is not specified, and a default trust anchor
+(@LDNS_TRUST_ANCHOR_FILE@) exists and contains a valid DNSKEY or DS record,
+it will be used as the trust anchor.
+
+.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\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.
+
+.SH "FILES"
+.TP
+@LDNS_TRUST_ANCHOR_FILE@
+The file from which trusted keys are loaded when no \fB-k\fR option is given.

+\mainpage LDNS Documentation
+
+\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.

+where:
+
+ID              A 16 bit identifier assigned by the program that
+                generates any kind of query.  This identifier is copied
+                the corresponding reply and can be used by the requester
+                to match up replies to outstanding queries.
+
+QR              A one bit field that specifies whether this message is a
+                query (0), or a response (1).
+
+OPCODE          A four bit field that specifies kind of query in this
+                message.  This value is set by the originator of a query
+                and copied into the response.  The values are:
+
+                0               a standard query (QUERY)
+
+                1               an inverse query (IQUERY)
+
+                2               a server status request (STATUS)
+
+                3-15            reserved for future use
+
+AA              Authoritative Answer - this bit is valid in responses,
+                and specifies that the responding name server is an
+                authority for the domain name in question section.
+
+                Note that the contents of the answer section may have
+                multiple owner names because of aliases.  The AA bit
+
+                corresponds to the name which matches the query name, or
+                the first owner name in the answer section.
+
+TC              TrunCation - specifies that this message was truncated
+                due to length greater than that permitted on the
+                transmission channel.
+
+RD              Recursion Desired - this bit may be set in a query and
+                is copied into the response.  If RD is set, it directs
+                the name server to pursue the query recursively.
+                Recursive query support is optional.
+
+RA              Recursion Available - this be is set or cleared in a
+                response, and denotes whether recursive query support is
+                available in the name server.
+
+Z               Reserved for future use.  Must be zero in all queries
+                and responses.
+
+RCODE           Response code - this 4 bit field is set as part of
+                responses.  The values have the following
+                interpretation:
+
+                0               No error condition
+
+                1               Format error - The name server was
+                                unable to interpret the query.
+
+                2               Server failure - The name server was
+                                unable to process this query due to a
+                                problem with the name server.
+
+                3               Name Error - Meaningful only for
+                                responses from an authoritative name
+                                server, this code signifies that the
+                                domain name referenced in the query does
+                                not exist.
+
+                4               Not Implemented - The name server does
+                                not support the requested kind of query.
+
+                5               Refused - The name server refuses to
+                                perform the specified operation for
+                                policy reasons.  For example, a name
+                                server may not wish to provide the
+                                information to the particular requester,
+                                or a name server may not wish to perform
+                                a particular operation (e.g., zone
+
+                                transfer) for particular data.
+
+                6-15            Reserved for future use.
+
+QDCOUNT         an unsigned 16 bit integer specifying the number of

+.It Fn archive_write_fail
+Always returns
+.Cm ARCHIVE_FATAL .
+This marks the archive object as being unusable;
+after calling this function, the only call that can succeed is
+.Fn archive_write_free
+to release the resources.
+This can be used to speed recovery when the archive creation
+must be aborted.
+Note that the created archive is likely to be malformed in this case; 
 .It Fn archive_write_close
 Complete the archive and invoke the close callback.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to `$srcdir/foo'.  In other projects, it is set to
+# `$srcdir', `$srcdir/..', or `$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory.  The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run.  This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+#    fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+#    fails if $ac_aux_dir is absolute,
+#    fails when called from a subdirectory in a VPATH build with
+#          a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir.  In an in-source build this is usually
+# harmless because $srcdir is `.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir.  That would be:
+#   am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+#   MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH.  The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+\`configure' configures yaml 0.1.4 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

+  --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.

+
    The prototype of a read handler. 
    
+
    The read handler is called when the parser needs to read more bytes from the source. The handler should write not more than size bytes to the buffer. The number of written bytes should be set to the length variable.
    
+
    Parameters:
    
+  
+    
+    
+    
+    
+  
    [in,out] data A pointer to an application data specified by yaml_parser_set_input(). 
    [out] buffer The buffer to write the data from the source. 
    [in] size The size of the buffer. 
    [out] size_read The actual number of bytes read from the source.
    
+  
    
+
    
+
    Returns:
    On success, the handler should return 1. If the handler failed, the returned value should be 0. On EOF, the handler should set the size_read to 0 and return 1.

    int yaml_parser_scan (yaml_parser_t *  parser, 
    yaml_token_t *  token 
    )
    
+
    
+
    
+
+
    Scan the input stream and produce the next token. 
    
+
    Call the function subsequently to produce a sequence of tokens corresponding to the input stream. The initial token has the type YAML_STREAM_START_TOKEN while the ending token has the type YAML_STREAM_END_TOKEN.
    
+
    An application is responsible for freeing any buffers associated with the produced token object using the yaml_token_delete function.
    
+
    An application must not alternate the calls of yaml_parser_scan() with the calls of yaml_parser_parse() or yaml_parser_load(). Doing this will break the parser.
    
+
    Parameters:
    
+  
+    
+    
+  
    [in,out] parser A parser object. 
    [out] token An empty token object.
    
+  
    
+
    
+
    Returns:
    1 if the function succeeded, 0 on error.

    int yaml_parser_parse (yaml_parser_t *  parser, 
    yaml_event_t *  event 
    )
    
+
    
+
    
+
+
    Parse the input stream and produce the next parsing event. 
    
+
    Call the function subsequently to produce a sequence of events corresponding to the input stream. The initial event has the type YAML_STREAM_START_EVENT while the ending event has the type YAML_STREAM_END_EVENT.
    
+
    An application is responsible for freeing any buffers associated with the produced event object using the yaml_event_delete() function.
    
+
    An application must not alternate the calls of yaml_parser_parse() with the calls of yaml_parser_scan() or yaml_parser_load(). Doing this will break the parser.
    
+
    Parameters:
    
+  
+    
+    
+  
    [in,out] parser A parser object. 
    [out] event An empty event object.
    
+  
    
+

    int yaml_parser_load (yaml_parser_t *  parser, 
    yaml_document_t *  document 
    )
    
+
    
+
    
+
+
    Parse the input stream and produce the next YAML document. 
    
+
    Call this function subsequently to produce a sequence of documents constituting the input stream.
    
+
    If the produced document has no root node, it means that the document end has been reached.
    
+
    An application is responsible for freeing any data associated with the produced document object using the yaml_document_delete() function.
    
+
    An application must not alternate the calls of yaml_parser_load() with the calls of yaml_parser_scan() or yaml_parser_parse(). Doing this will break the parser.
    
+
    Parameters:
    
+  
+    
+    
+  
    [in,out] parser A parser object. 
    [out] document An empty document object.
    
+  
    
+
    
+
    Returns:
    1 if the function succeeded, 0 on error.

+ * Introduction
+ * ************
+ *
+ * The following notes assume that you are familiar with the YAML specification
+ * (http://yaml.org/spec/cvs/current.html).  We mostly follow it, although in
+ * some cases we are less restrictive that it requires.
+ *
+ * The process of transforming a YAML stream into a sequence of events is
+ * divided on two steps: Scanning and Parsing.
+ *
+ * The Scanner transforms the input stream into a sequence of tokens, while the
+ * parser transform the sequence of tokens produced by the Scanner into a
+ * sequence of parsing events.
+ *
+ * The Scanner is rather clever and complicated. The Parser, on the contrary,
+ * is a straightforward implementation of a recursive-descendant parser (or,
+ * LL(1) parser, as it is usually called).
+ *
+ * Actually there are two issues of Scanning that might be called "clever", the
+ * rest is quite straightforward.  The issues are "block collection start" and
+ * "simple keys".  Both issues are explained below in details.
+ *
+ * Here the Scanning step is explained and implemented.  We start with the list
+ * of all the tokens produced by the Scanner together with short descriptions.
+ *
+ * Now, tokens:
+ *
+ *      STREAM-START(encoding)          # The stream start.
+ *      STREAM-END                      # The stream end.
+ *      VERSION-DIRECTIVE(major,minor)  # The '%YAML' directive.
+ *      TAG-DIRECTIVE(handle,prefix)    # The '%TAG' directive.
+ *      DOCUMENT-START                  # '---'
+ *      DOCUMENT-END                    # '...'
+ *      BLOCK-SEQUENCE-START            # Indentation increase denoting a block
+ *      BLOCK-MAPPING-START             # sequence or a block mapping.
+ *      BLOCK-END                       # Indentation decrease.
+ *      FLOW-SEQUENCE-START             # '['
+ *      FLOW-SEQUENCE-END               # ']'
+ *      BLOCK-SEQUENCE-START            # '{'
+ *      BLOCK-SEQUENCE-END              # '}'
+ *      BLOCK-ENTRY                     # '-'
+ *      FLOW-ENTRY                      # ','
+ *      KEY                             # '?' or nothing (simple keys).
+ *      VALUE                           # ':'
+ *      ALIAS(anchor)                   # '*anchor'
+ *      ANCHOR(anchor)                  # '&anchor'
+ *      TAG(handle,suffix)              # '!handle!suffix'
+ *      SCALAR(value,style)             # A scalar.
+ *
+ * The following two tokens are "virtual" tokens denoting the beginning and the
+ * end of the stream:
+ *
+ *      STREAM-START(encoding)
+ *      STREAM-END
+ *
+ * We pass the information about the input stream encoding with the
+ * STREAM-START token.
+ *
+ * The next two tokens are responsible for tags:
+ *
+ *      VERSION-DIRECTIVE(major,minor)
+ *      TAG-DIRECTIVE(handle,prefix)
+ *
+ * Example:
+ *
+ *      %YAML   1.1
+ *      %TAG    !   !foo
+ *      %TAG    !yaml!  tag:yaml.org,2002:
+ *      ---
+ *
+ * The correspoding sequence of tokens:
+ *
+ *      STREAM-START(utf-8)
+ *      VERSION-DIRECTIVE(1,1)
+ *      TAG-DIRECTIVE("!","!foo")
+ *      TAG-DIRECTIVE("!yaml","tag:yaml.org,2002:")
+ *      DOCUMENT-START
+ *      STREAM-END
+ *
+ * Note that the VERSION-DIRECTIVE and TAG-DIRECTIVE tokens occupy a whole
+ * line.
+ *
+ * The document start and end indicators are represented by:
+ *
+ *      DOCUMENT-START
+ *      DOCUMENT-END
+ *
+ * Note that if a YAML stream contains an implicit document (without '---'
+ * and '...' indicators), no DOCUMENT-START and DOCUMENT-END tokens will be
+ * produced.
+ *
+ * In the following examples, we present whole documents together with the
+ * produced tokens.
+ *
+ *      1. An implicit document:
+ *
+ *          'a scalar'
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          SCALAR("a scalar",single-quoted)
+ *          STREAM-END
+ *
+ *      2. An explicit document:
+ *
+ *          ---
+ *          'a scalar'
+ *          ...
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          DOCUMENT-START
+ *          SCALAR("a scalar",single-quoted)
+ *          DOCUMENT-END
+ *          STREAM-END
+ *
+ *      3. Several documents in a stream:
+ *
+ *          'a scalar'
+ *          ---
+ *          'another scalar'
+ *          ---
+ *          'yet another scalar'
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          SCALAR("a scalar",single-quoted)
+ *          DOCUMENT-START
+ *          SCALAR("another scalar",single-quoted)
+ *          DOCUMENT-START
+ *          SCALAR("yet another scalar",single-quoted)
+ *          STREAM-END
+ *
+ * We have already introduced the SCALAR token above.  The following tokens are
+ * used to describe aliases, anchors, tag, and scalars:
+ *
+ *      ALIAS(anchor)
+ *      ANCHOR(anchor)
+ *      TAG(handle,suffix)
+ *      SCALAR(value,style)
+ *
+ * The following series of examples illustrate the usage of these tokens:
+ *
+ *      1. A recursive sequence:
+ *
+ *          &A [ *A ]
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          ANCHOR("A")
+ *          FLOW-SEQUENCE-START
+ *          ALIAS("A")
+ *          FLOW-SEQUENCE-END
+ *          STREAM-END
+ *
+ *      2. A tagged scalar:
+ *
+ *          !!float "3.14"  # A good approximation.
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          TAG("!!","float")
+ *          SCALAR("3.14",double-quoted)
+ *          STREAM-END
+ *
+ *      3. Various scalar styles:
+ *
+ *          --- # Implicit empty plain scalars do not produce tokens.
+ *          --- a plain scalar
+ *          --- 'a single-quoted scalar'
+ *          --- "a double-quoted scalar"
+ *          --- |-
+ *            a literal scalar
+ *          --- >-
+ *            a folded
+ *            scalar
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          DOCUMENT-START
+ *          DOCUMENT-START
+ *          SCALAR("a plain scalar",plain)
+ *          DOCUMENT-START
+ *          SCALAR("a single-quoted scalar",single-quoted)
+ *          DOCUMENT-START
+ *          SCALAR("a double-quoted scalar",double-quoted)
+ *          DOCUMENT-START
+ *          SCALAR("a literal scalar",literal)
+ *          DOCUMENT-START
+ *          SCALAR("a folded scalar",folded)
+ *          STREAM-END
+ *
+ * Now it's time to review collection-related tokens. We will start with
+ * flow collections:
+ *
+ *      FLOW-SEQUENCE-START
+ *      FLOW-SEQUENCE-END
+ *      FLOW-MAPPING-START
+ *      FLOW-MAPPING-END
+ *      FLOW-ENTRY
+ *      KEY
+ *      VALUE
+ *
+ * The tokens FLOW-SEQUENCE-START, FLOW-SEQUENCE-END, FLOW-MAPPING-START, and
+ * FLOW-MAPPING-END represent the indicators '[', ']', '{', and '}'
+ * correspondingly.  FLOW-ENTRY represent the ',' indicator.  Finally the
+ * indicators '?' and ':', which are used for denoting mapping keys and values,
+ * are represented by the KEY and VALUE tokens.
+ *
+ * The following examples show flow collections:
+ *
+ *      1. A flow sequence:
+ *
+ *          [item 1, item 2, item 3]
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          FLOW-SEQUENCE-START
+ *          SCALAR("item 1",plain)
+ *          FLOW-ENTRY
+ *          SCALAR("item 2",plain)
+ *          FLOW-ENTRY
+ *          SCALAR("item 3",plain)
+ *          FLOW-SEQUENCE-END
+ *          STREAM-END
+ *
+ *      2. A flow mapping:
+ *
+ *          {
+ *              a simple key: a value,  # Note that the KEY token is produced.
+ *              ? a complex key: another value,
+ *          }
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          FLOW-MAPPING-START
+ *          KEY
+ *          SCALAR("a simple key",plain)
+ *          VALUE
+ *          SCALAR("a value",plain)
+ *          FLOW-ENTRY
+ *          KEY
+ *          SCALAR("a complex key",plain)
+ *          VALUE
+ *          SCALAR("another value",plain)
+ *          FLOW-ENTRY
+ *          FLOW-MAPPING-END
+ *          STREAM-END
+ *
+ * A simple key is a key which is not denoted by the '?' indicator.  Note that
+ * the Scanner still produce the KEY token whenever it encounters a simple key.
+ *
+ * For scanning block collections, the following tokens are used (note that we
+ * repeat KEY and VALUE here):
+ *
+ *      BLOCK-SEQUENCE-START
+ *      BLOCK-MAPPING-START
+ *      BLOCK-END
+ *      BLOCK-ENTRY
+ *      KEY
+ *      VALUE
+ *
+ * The tokens BLOCK-SEQUENCE-START and BLOCK-MAPPING-START denote indentation
+ * increase that precedes a block collection (cf. the INDENT token in Python).
+ * The token BLOCK-END denote indentation decrease that ends a block collection
+ * (cf. the DEDENT token in Python).  However YAML has some syntax pecularities
+ * that makes detections of these tokens more complex.
+ *
+ * The tokens BLOCK-ENTRY, KEY, and VALUE are used to represent the indicators
+ * '-', '?', and ':' correspondingly.
+ *
+ * The following examples show how the tokens BLOCK-SEQUENCE-START,
+ * BLOCK-MAPPING-START, and BLOCK-END are emitted by the Scanner:
+ *
+ *      1. Block sequences:
+ *
+ *          - item 1
+ *          - item 2
+ *          -
+ *            - item 3.1
+ *            - item 3.2
+ *          -
+ *            key 1: value 1
+ *            key 2: value 2
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          BLOCK-SEQUENCE-START
+ *          BLOCK-ENTRY
+ *          SCALAR("item 1",plain)
+ *          BLOCK-ENTRY
+ *          SCALAR("item 2",plain)
+ *          BLOCK-ENTRY
+ *          BLOCK-SEQUENCE-START
+ *          BLOCK-ENTRY
+ *          SCALAR("item 3.1",plain)
+ *          BLOCK-ENTRY
+ *          SCALAR("item 3.2",plain)
+ *          BLOCK-END
+ *          BLOCK-ENTRY
+ *          BLOCK-MAPPING-START
+ *          KEY
+ *          SCALAR("key 1",plain)
+ *          VALUE
+ *          SCALAR("value 1",plain)
+ *          KEY
+ *          SCALAR("key 2",plain)
+ *          VALUE
+ *          SCALAR("value 2",plain)
+ *          BLOCK-END
+ *          BLOCK-END
+ *          STREAM-END
+ *
+ *      2. Block mappings:
+ *
+ *          a simple key: a value   # The KEY token is produced here.
+ *          ? a complex key
+ *          : another value
+ *          a mapping:
+ *            key 1: value 1
+ *            key 2: value 2
+ *          a sequence:
+ *            - item 1
+ *            - item 2
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          BLOCK-MAPPING-START
+ *          KEY
+ *          SCALAR("a simple key",plain)
+ *          VALUE
+ *          SCALAR("a value",plain)
+ *          KEY
+ *          SCALAR("a complex key",plain)
+ *          VALUE
+ *          SCALAR("another value",plain)
+ *          KEY
+ *          SCALAR("a mapping",plain)
+ *          BLOCK-MAPPING-START
+ *          KEY
+ *          SCALAR("key 1",plain)
+ *          VALUE
+ *          SCALAR("value 1",plain)
+ *          KEY
+ *          SCALAR("key 2",plain)
+ *          VALUE
+ *          SCALAR("value 2",plain)
+ *          BLOCK-END
+ *          KEY
+ *          SCALAR("a sequence",plain)
+ *          VALUE
+ *          BLOCK-SEQUENCE-START
+ *          BLOCK-ENTRY
+ *          SCALAR("item 1",plain)
+ *          BLOCK-ENTRY
+ *          SCALAR("item 2",plain)
+ *          BLOCK-END
+ *          BLOCK-END
+ *          STREAM-END
+ *
+ * YAML does not always require to start a new block collection from a new
+ * line.  If the current line contains only '-', '?', and ':' indicators, a new
+ * block collection may start at the current line.  The following examples
+ * illustrate this case:
+ *
+ *      1. Collections in a sequence:
+ *
+ *          - - item 1
+ *            - item 2
+ *          - key 1: value 1
+ *            key 2: value 2
+ *          - ? complex key
+ *            : complex value
+ *
+ *      Tokens:
+ *
+ *          STREAM-START(utf-8)
+ *          BLOCK-SEQUENCE-START
+ *          BLOCK-ENTRY
+ *          BLOCK-SEQUENCE-START
+ *          BLOCK-ENTRY
+ *          SCALAR("item 1",plain)
+ *          BLOCK-ENTRY
+ *          SCALAR("item 2",plain)
+ *          BLOCK-END
+ *          BLOCK-ENTRY
+ *          BLOCK-MAPPING-START
+ *          KEY
+ *          SCALAR("key 1",plain)
+ *          VALUE
+ *          SCALAR("value 1",plain)
+ *          KEY
+ *          SCALAR("key 2",plain)
+ *          VALUE

+ *          BLOCK-END
+ *          BLOCK-ENTRY

+ *          VALUE
+ *          SCALAR("complex value")
+ *          BLOCK-END
+ *          BLOCK-END
+ *          STREAM-END
+ *
+ *      2. Collections in a mapping:
+ *
+ *          ? a sequence
+ *          : - item 1
+ *            - item 2
+ *          ? a mapping

+ *
+ * YAML also permits non-indented sequences if they are included into a block
