+ * consider that the real grammars recognized by the parsers are not
+ * those of the standards.  As a matter of fact, our parsers are more
+ * liberal than the spec when there is no ambiguity.

+ * In T.61, the codes xC1 to xCF (excluding xC9, unused) are non-spacing
+ * accents of some form or another. There are predefined combinations
+ * for certain characters, but they can also be used arbitrarily. The
+ * table at dkuug.dk maps these accents to the E000 "private use" range
+ * of the Unicode space, but I believe they more properly belong in the
+ * 0300 range (non-spacing accents). The transformation is complicated
+ * slightly because Unicode wants the non-spacing character to follow
+ * the base character, while T.61 has the non-spacing character leading.
+ * Also, T.61 specifically recognizes certain combined pairs as "characters"
+ * but doesn't specify how to treat unrecognized pairs. This code will
+ * always attempt to combine pairs when a known Unicode composite exists.

+ * This package provides several types of thread operation debugging:
+ *
+ * - Check the results of operations on threads, mutexes, condition
+ *   variables and read/write locks.  Also check some thread pool
+ *   operations, but not those for which failure can happen in normal
+ *   slapd operation.
+ *
+ * - Wrap those types except threads and pools in structs with state
+ *   information, and check that on all operations:
+ *
+ *   + Check that the resources are initialized and are only used at
+ *     their original address (i.e. not realloced or copied).
+ *
+ *   + Check the owner (thread ID) on mutex operations.
+ *
+ *   + Optionally allocate a reference to a byte of dummy memory.
+ *     This lets malloc debuggers see some incorrect use as memory
+ *     leaks, access to freed memory, etc.
+ *
+ * - Print an error message and by default abort() upon errors.
+ *
+ * - Print a count of leaked thread resources after cleanup.
+ *
+ * Compile-time (./configure) setup:  Macros defined in CPPFLAGS.
+ *
+ *   LDAP_THREAD_DEBUG or LDAP_THREAD_DEBUG=2
+ *      Enables debugging, but value & 2 turns off type wrapping.
+ *
+ *   LDAP_UINTPTR_T=integer type to hold pointers, preferably unsigned.
+ *      Used by dummy memory option "scramble". Default = unsigned long.
+ *
+ *   LDAP_DEBUG_THREAD_NONE = initializer for a "no thread" thread ID.
+ *
+ *   In addition, you may need to set up an implementation-specific way
+ *      to enable whatever error checking your thread library provides.
+ *      Currently only implemented for Posix threads (pthreads), where
+ *      you may need to define LDAP_INT_THREAD_MUTEXATTR.  The default
+ *      is PTHREAD_MUTEX_ERRORCHECK, or PTHREAD_MUTEX_ERRORCHECK_NP for
+ *      Linux threads.  See pthread_mutexattr_settype(3).
+ *
+ * Run-time configuration:
+ *
+ *  Memory debugging tools:
+ *   Tools that report uninitialized memory accesses should disable
+ *   such warnings about the function debug_already_initialized().
+ *   Alternatively, include "noreinit" (below) in $LDAP_THREAD_DEBUG.
+ *
+ *  Environment variable $LDAP_THREAD_DEBUG:
+ *   The variable may contain a comma- or space-separated option list.
+ *   Options:
+ *      off      - Disable this package.  (It still slows things down).
+ *      tracethreads - Report create/join/exit/kill of threads.
+ *      noabort  - Do not abort() on errors.
+ *      noerror  - Do not report errors.  Implies noabort.
+ *      nocount  - Do not report counts of unreleased resources.
+ *      nosync   - Disable tests that use synchronizaion and thus
+ *                 clearly affect thread scheduling:
+ *                 Implies nocount, and cancels threadID if that is set.
+ *                 Note that if you turn on tracethreads or malloc
+ *                 debugging, these also use library calls which may
+ *                 affect thread scheduling (fprintf and malloc).
+ *   The following options do not apply if type wrapping is disabled:
+ *      nomem    - Do not check memory operations.
+ *                 Implies noreinit,noalloc.
+ *      noreinit - Do not catch reinitialization of existing resources.
+ *                 (That test accesses uninitialized memory).
+ *      threadID - Trace thread IDs.  Currently mostly useless.
+ *     Malloc debugging -- allocate dummy memory for initialized
+ *     resources, so malloc debuggers will report them as memory leaks:
+ *      noalloc  - Default.  Do not allocate dummy memory.
+ *      alloc    - Store a pointer to dummy memory.   However, leak
+ *                 detectors might not catch unreleased resources in
+ *                 global variables.
+ *      scramble - Store bitwise complement of dummy memory pointer.
+ *                 That never escapes memory leak detectors -
+ *                 but detection while the program is running will
+ *                 report active resources as leaks.  Do not
+ *                 use this if a garbage collector is in use:-)
+ *      adjptr   - Point to end of dummy memory.
+ *                 Purify reports these as "potential leaks" (PLK).
+ *                 I have not checked other malloc debuggers.

+# Values that contain spaces should be placed between quotes (" ")

+/** @page starting Getting Started
+
+LMDB is compact, fast, powerful, and robust and implements a simplified
+variant of the BerkeleyDB (BDB) API. (BDB is also very powerful, and verbosely
+documented in its own right.) After reading this page, the main
+\ref mdb documentation should make sense. Thanks to Bert Hubert
+for creating the
+<a href="https://github.com/ahupowerdns/ahutils/blob/master/lmdb-semantics.md">
+initial version</a> of this writeup.
+
+Everything starts with an environment, created by #mdb_env_create().
+Once created, this environment must also be opened with #mdb_env_open().
+
+#mdb_env_open() gets passed a name which is interpreted as a directory
+path. Note that this directory must exist already, it is not created
+for you. Within that directory, a lock file and a storage file will be
+generated. If you don't want to use a directory, you can pass the
+#MDB_NOSUBDIR option, in which case the path you provided is used
+directly as the data file, and another file with a "-lock" suffix
+added will be used for the lock file.
+
+Once the environment is open, a transaction can be created within it
+using #mdb_txn_begin(). Transactions may be read-write or read-only,
+and read-write transactions may be nested. A transaction must only
+be used by one thread at a time. Transactions are always required,
+even for read-only access. The transaction provides a consistent
+view of the data.
+
+Once a transaction has been created, a database can be opened within it
+using #mdb_dbi_open(). If only one database will ever be used in the
+environment, a NULL can be passed as the database name. For named
+databases, the #MDB_CREATE flag must be used to create the database
+if it doesn't already exist. Also, #mdb_env_set_maxdbs() must be
+called after #mdb_env_create() and before #mdb_env_open() to set the
+maximum number of named databases you want to support.
+
+Note: a single transaction can open multiple databases. Generally
+databases should only be opened once, by the first transaction in
+the process. After the first transaction completes, the database
+handles can freely be used by all subsequent transactions.
+
+Within a transaction, #mdb_get() and #mdb_put() can store single
+key/value pairs if that is all you need to do (but see \ref Cursors
+below if you want to do more).
+
+A key/value pair is expressed as two #MDB_val structures. This struct
+has two fields, \c mv_size and \c mv_data. The data is a \c void pointer to
+an array of \c mv_size bytes.
+
+Because LMDB is very efficient (and usually zero-copy), the data returned
+in an #MDB_val structure may be memory-mapped straight from disk. In
+other words <b>look but do not touch</b> (or free() for that matter).
+Once a transaction is closed, the values can no longer be used, so
+make a copy if you need to keep them after that.
+
+@section Cursors Cursors
+
+To do more powerful things, we must use a cursor.
+
+Within the transaction, a cursor can be created with #mdb_cursor_open().
+With this cursor we can store/retrieve/delete (multiple) values using
+#mdb_cursor_get(), #mdb_cursor_put(), and #mdb_cursor_del().
+
+#mdb_cursor_get() positions itself depending on the cursor operation
+requested, and for some operations, on the supplied key. For example,
+to list all key/value pairs in a database, use operation #MDB_FIRST for
+the first call to #mdb_cursor_get(), and #MDB_NEXT on subsequent calls,
+until the end is hit.
+
+To retrieve all keys starting from a specified key value, use #MDB_SET.
+For more cursor operations, see the \ref mdb docs.
+
+When using #mdb_cursor_put(), either the function will position the
+cursor for you based on the \b key, or you can use operation
+#MDB_CURRENT to use the current position of the cursor. Note that
+\b key must then match the current position's key.
+
+@subsection summary Summarizing the Opening
+
+So we have a cursor in a transaction which opened a database in an
+environment which is opened from a filesystem after it was
+separately created.
+
+Or, we create an environment, open it from a filesystem, create a
+transaction within it, open a database within that transaction,
+and create a cursor within all of the above.
+
+Got it?
+
+@section thrproc Threads and Processes
+
+LMDB uses POSIX locks on files, and these locks have issues if one
+process opens a file multiple times. Because of this, do not
+#mdb_env_open() a file multiple times from a single process. Instead,
+share the LMDB environment that has opened the file across all threads.
+Otherwise, if a single process opens the same environment multiple times,
+closing it once will remove all the locks held on it, and the other
+instances will be vulnerable to corruption from other processes.
+
+Also note that a transaction is tied to one thread by default using
+Thread Local Storage. If you want to pass read-only transactions across
+threads, you can use the #MDB_NOTLS option on the environment.
+
+@section txns Transactions, Rollbacks, etc.
+
+To actually get anything done, a transaction must be committed using
+#mdb_txn_commit(). Alternatively, all of a transaction's operations
+can be discarded using #mdb_txn_abort(). In a read-only transaction,
+any cursors will \b not automatically be freed. In a read-write
+transaction, all cursors will be freed and must not be used again.
+
+For read-only transactions, obviously there is nothing to commit to
+storage. The transaction still must eventually be aborted to close
+any database handle(s) opened in it, or committed to keep the
+database handles around for reuse in new transactions.
+
+In addition, as long as a transaction is open, a consistent view of
+the database is kept alive, which requires storage. A read-only
+transaction that no longer requires this consistent view should
+be terminated (committed or aborted) when the view is no longer
+needed (but see below for an optimization).
+
+There can be multiple simultaneously active read-only transactions
+but only one that can write. Once a single read-write transaction
+is opened, all further attempts to begin one will block until the
+first one is committed or aborted. This has no effect on read-only
+transactions, however, and they may continue to be opened at any time.
+
+@section dupkeys Duplicate Keys
+
+#mdb_get() and #mdb_put() respectively have no and only some support
+for multiple key/value pairs with identical keys. If there are multiple
+values for a key, #mdb_get() will only return the first value.
+
+When multiple values for one key are required, pass the #MDB_DUPSORT
+flag to #mdb_dbi_open(). In an #MDB_DUPSORT database, by default
+#mdb_put() will not replace the value for a key if the key existed
+already. Instead it will add the new value to the key. In addition,
+#mdb_del() will pay attention to the value field too, allowing for
+specific values of a key to be deleted.
+
+Finally, additional cursor operations become available for
+traversing through and retrieving duplicate values.
+
+@section optim Some Optimization
+
+If you frequently begin and abort read-only transactions, as an
+optimization, it is possible to only reset and renew a transaction.
+
+#mdb_txn_reset() releases any old copies of data kept around for
+a read-only transaction. To reuse this reset transaction, call
+#mdb_txn_renew() on it. Any cursors in this transaction must also
+be renewed using #mdb_cursor_renew().
+
+Note that #mdb_txn_reset() is similar to #mdb_txn_abort() and will
+close any databases you opened within the transaction.
+
+To permanently free a transaction, reset or not, use #mdb_txn_abort().
+
+@section cleanup Cleaning Up
+
+For read-only transactions, any cursors created within it must
+be closed using #mdb_cursor_close().
+
+It is very rarely necessary to close a database handle, and in
+general they should just be left open.
+
+@section onward The Full API
+
+The full \ref mdb documentation lists further details, like how to:
+
+  \li size a database (the default limits are intentionally small)
+  \li drop and clean a database
+  \li detect and report errors
+  \li optimize (bulk) loading speed
+  \li (temporarily) reduce robustness to gain even more speed
+  \li gather statistics about the database
+  \li define custom sort orders

+ *	from the mapped memory, so no malloc's or memcpy's occur during
+ *	data fetches. As such, the library is extremely simple because it
+ *	requires no page caching layer of its own, and it is extremely high
+ *	performance and memory-efficient. It is also fully transactional with
+ *	full ACID semantics, and when the memory map is read-only, the
+ *	database integrity cannot be corrupted by stray pointer writes from
+ *	application code.
+ *
+ *	The library is fully thread-aware and supports concurrent read/write
+ *	access from multiple processes and threads. Data pages use a copy-on-
+ *	write strategy so no active data pages are ever overwritten, which
+ *	also provides resistance to corruption and eliminates the need of any
+ *	special recovery procedures after a system crash. Writes are fully
+ *	serialized; only one write transaction may be active at a time, which
+ *	guarantees that writers can never deadlock. The database structure is
+ *	multi-versioned so readers run with no locks; writers cannot block
+ *	readers, and readers don't block writers.
+ *
+ *	Unlike other well-known database mechanisms which use either write-ahead
+ *	transaction logs or append-only data writes, LMDB requires no maintenance
+ *	during operation. Both write-ahead loggers and append-only databases
+ *	require periodic checkpointing and/or compaction of their log or database
+ *	files otherwise they grow without bound. LMDB tracks free pages within
+ *	the database and re-uses them for new write operations, so the database
+ *	size does not grow without bound in normal use.
+ *
+ *	The memory map can be used as a read-only or read-write map. It is
+ *	read-only by default as this provides total immunity to corruption.
+ *	Using read-write mode offers much higher write performance, but adds
+ *	the possibility for stray application writes thru pointers to silently
+ *	corrupt the database. Of course if your application code is known to
+ *	be bug-free (...) then this is not an issue.
+ *
+ *	If this is your first time using a transactional embedded key/value
+ *	store, you may find the \ref starting page to be helpful.
+ *
+ *	@section caveats_sec Caveats
+ *	Troubleshooting the lock file, plus semaphores on BSD systems:
+ *
+ *	- A broken lockfile can cause sync issues.
+ *	  Stale reader transactions left behind by an aborted program
+ *	  cause further writes to grow the database quickly, and
+ *	  stale locks can block further operation.
+ *
+ *	  Fix: Check for stale readers periodically, using the
+ *	  #mdb_reader_check function or the \ref mdb_stat_1 "mdb_stat" tool.
+ *	  Stale writers will be cleared automatically on some systems:
+ *	  - Windows - automatic
+ *	  - Linux, systems using POSIX mutexes with Robust option - automatic
+ *	  - not on BSD, systems using POSIX semaphores.
+ *	  Otherwise just make all programs using the database close it;
+ *	  the lockfile is always reset on first open of the environment.
+ *
+ *	- On BSD systems or others configured with MDB_USE_POSIX_SEM,
+ *	  startup can fail due to semaphores owned by another userid.
+ *
+ *	  Fix: Open and close the database as the user which owns the
+ *	  semaphores (likely last user) or as root, while no other
+ *	  process is using the database.
+ *
+ *	Restrictions/caveats (in addition to those listed for some functions):
+ *
+ *	- Only the database owner should normally use the database on
+ *	  BSD systems or when otherwise configured with MDB_USE_POSIX_SEM.
+ *	  Multiple users can cause startup to fail later, as noted above.
+ *
+ *	- There is normally no pure read-only mode, since readers need write
+ *	  access to locks and lock file. Exceptions: On read-only filesystems
+ *	  or with the #MDB_NOLOCK flag described under #mdb_env_open().
+ *
+ *	- An LMDB configuration will often reserve considerable \b unused
+ *	  memory address space and maybe file size for future growth.
+ *	  This does not use actual memory or disk space, but users may need
+ *	  to understand the difference so they won't be scared off.
+ *
+ *	- By default, in versions before 0.9.10, unused portions of the data
+ *	  file might receive garbage data from memory freed by other code.
+ *	  (This does not happen when using the #MDB_WRITEMAP flag.) As of
+ *	  0.9.10 the default behavior is to initialize such memory before
+ *	  writing to the data file. Since there may be a slight performance
+ *	  cost due to this initialization, applications may disable it using
+ *	  the #MDB_NOMEMINIT flag. Applications handling sensitive data
+ *	  which must not be written should not use this flag. This flag is
+ *	  irrelevant when using #MDB_WRITEMAP.
+ *
+ *	- A thread can only use one transaction at a time, plus any child
+ *	  transactions.  Each transaction belongs to one thread.  See below.
+ *	  The #MDB_NOTLS flag changes this for read-only transactions.
+ *
+ *	- Use an MDB_env* in the process which opened it, not after fork().
+ *
+ *	- Do not have open an LMDB database twice in the same process at
+ *	  the same time.  Not even from a plain open() call - close()ing it
+ *	  breaks fcntl() advisory locking.  (It is OK to reopen it after
+ *	  fork() - exec*(), since the lockfile has FD_CLOEXEC set.)
+ *
+ *	- Avoid long-lived transactions.  Read transactions prevent
+ *	  reuse of pages freed by newer write transactions, thus the
+ *	  database can grow quickly.  Write transactions prevent
+ *	  other write transactions, since writes are serialized.
+ *
+ *	- Avoid suspending a process with active transactions.  These
+ *	  would then be "long-lived" as above.  Also read transactions
+ *	  suspended when writers commit could sometimes see wrong data.
+ *
+ *	...when several processes can use a database concurrently:
+ *
+ *	- Avoid aborting a process with an active transaction.
+ *	  The transaction becomes "long-lived" as above until a check
+ *	  for stale readers is performed or the lockfile is reset,
+ *	  since the process may not remove it from the lockfile.
+ *
+ *	  This does not apply to write transactions if the system clears
+ *	  stale writers, see above.
+ *
+ *	- If you do that anyway, do a periodic check for stale readers. Or
+ *	  close the environment once in a while, so the lockfile can get reset.
+ *
+ *	- Do not use LMDB databases on remote filesystems, even between
+ *	  processes on the same host.  This breaks flock() on some OSes,
+ *	  possibly memory map sync, and certainly sync between programs
+ *	  on different hosts.
+ *
+ *	- Opening a database can fail if another process is opening or
+ *	  closing it at exactly the same time.

+	 *		If successful, the memory map will always reside at the same virtual address
+	 *		and pointers used to reference data items in the database will be constant
+	 *		across multiple invocations. This option may not always work, depending on
+	 *		how the operating system has allocated memory to shared libraries and other uses.
+	 *		The feature is highly experimental.
+	 *	<li>#MDB_NOSUBDIR
+	 *		By default, LMDB creates its environment in a directory whose
+	 *		pathname is given in \b path, and creates its data and lock files
+	 *		under that directory. With this option, \b path is used as-is for
+	 *		the database main data file. The database lock file is the \b path
+	 *		with "-lock" appended.
+	 *	<li>#MDB_RDONLY
+	 *		Open the environment in read-only mode. No write operations will be
+	 *		allowed. LMDB will still modify the lock file - except on read-only
+	 *		filesystems, where LMDB does not use locks.
+	 *	<li>#MDB_WRITEMAP
+	 *		Use a writeable memory map unless MDB_RDONLY is set. This uses
+	 *		fewer mallocs but loses protection from application bugs
+	 *		like wild pointer writes and other bad updates into the database.
+	 *		This may be slightly faster for DBs that fit entirely in RAM, but
+	 *		is slower for DBs larger than RAM.
+	 *		Incompatible with nested transactions.
+	 *		Do not mix processes with and without MDB_WRITEMAP on the same
+	 *		environment.  This can defeat durability (#mdb_env_sync etc).
+	 *	<li>#MDB_NOMETASYNC
+	 *		Flush system buffers to disk only once per transaction, omit the
+	 *		metadata flush. Defer that until the system flushes files to disk,
+	 *		or next non-MDB_RDONLY commit or #mdb_env_sync(). This optimization
+	 *		maintains database integrity, but a system crash may undo the last
+	 *		committed transaction. I.e. it preserves the ACI (atomicity,
+	 *		consistency, isolation) but not D (durability) database property.
+	 *		This flag may be changed at any time using #mdb_env_set_flags().
+	 *	<li>#MDB_NOSYNC
+	 *		Don't flush system buffers to disk when committing a transaction.
+	 *		This optimization means a system crash can corrupt the database or
+	 *		lose the last transactions if buffers are not yet flushed to disk.
+	 *		The risk is governed by how often the system flushes dirty buffers
+	 *		to disk and how often #mdb_env_sync() is called.  However, if the
+	 *		filesystem preserves write order and the #MDB_WRITEMAP flag is not
+	 *		used, transactions exhibit ACI (atomicity, consistency, isolation)
+	 *		properties and only lose D (durability).  I.e. database integrity
+	 *		is maintained, but a system crash may undo the final transactions.
+	 *		Note that (#MDB_NOSYNC | #MDB_WRITEMAP) leaves the system with no
+	 *		hint for when to write transactions to disk, unless #mdb_env_sync()
+	 *		is called. (#MDB_MAPASYNC | #MDB_WRITEMAP) may be preferable.
+	 *		This flag may be changed at any time using #mdb_env_set_flags().
+	 *	<li>#MDB_MAPASYNC
+	 *		When using #MDB_WRITEMAP, use asynchronous flushes to disk.
+	 *		As with #MDB_NOSYNC, a system crash can then corrupt the
+	 *		database or lose the last transactions. Calling #mdb_env_sync()
+	 *		ensures on-disk database integrity until next commit.
+	 *		This flag may be changed at any time using #mdb_env_set_flags().
+	 *	<li>#MDB_NOTLS
+	 *		Don't use Thread-Local Storage. Tie reader locktable slots to
+	 *		#MDB_txn objects instead of to threads. I.e. #mdb_txn_reset() keeps
+	 *		the slot reseved for the #MDB_txn object. A thread may use parallel
+	 *		read-only transactions. A read-only transaction may span threads if
+	 *		the user synchronizes its use. Applications that multiplex many
+	 *		user threads over individual OS threads need this option. Such an
+	 *		application must also serialize the write transactions in an OS
+	 *		thread, since LMDB's write locking is unaware of the user threads.
+	 *	<li>#MDB_NOLOCK
+	 *		Don't do any locking. If concurrent access is anticipated, the
+	 *		caller must manage all concurrency itself. For proper operation
+	 *		the caller must enforce single-writer semantics, and must ensure
+	 *		that no readers are using old transactions while a writer is
+	 *		active. The simplest approach is to use an exclusive lock so that
+	 *		no readers may be active at all when a writer begins.
+	 *	<li>#MDB_NORDAHEAD
+	 *		Turn off readahead. Most operating systems perform readahead on
+	 *		read requests by default. This option turns it off if the OS
+	 *		supports it. Turning it off may help random read performance
+	 *		when the DB is larger than RAM and system RAM is full.
+	 *		The option is not implemented on Windows.
+	 *	<li>#MDB_NOMEMINIT
+	 *		Don't initialize malloc'd memory before writing to unused spaces
+	 *		in the data file. By default, memory for pages written to the data
+	 *		file is obtained using malloc. While these pages may be reused in
+	 *		subsequent transactions, freshly malloc'd pages will be initialized
+	 *		to zeroes before use. This avoids persisting leftover data from other
+	 *		code (that used the heap and subsequently freed the memory) into the
+	 *		data file. Note that many other system libraries may allocate
+	 *		and free memory from the heap for arbitrary uses. E.g., stdio may
+	 *		use the heap for file I/O buffers. This initialization step has a
+	 *		modest performance cost so some applications may want to disable
+	 *		it using this flag. This option can be a problem for applications
+	 *		which handle sensitive data like passwords, and it makes memory
+	 *		checkers like Valgrind noisy. This flag is not needed with #MDB_WRITEMAP,
+	 *		which writes directly to the mmap instead of using malloc for pages. The
+	 *		initialization is also skipped if #MDB_RESERVE is used; the
+	 *		caller is expected to overwrite all of the memory that was
+	 *		reserved in that case.
+	 *		This flag may be changed at any time using #mdb_env_set_flags().

+/**	@defgroup readers	Reader Lock Table
+ *	Readers don't acquire any locks for their data access. Instead, they
+ *	simply record their transaction ID in the reader table. The reader
+ *	mutex is needed just to find an empty slot in the reader table. The
+ *	slot's address is saved in thread-specific data so that subsequent read
+ *	transactions started by the same thread need no further locking to proceed.
+ *
+ *	If #MDB_NOTLS is set, the slot address is not saved in thread-specific data.
+ *
+ *	No reader table is used if the database is on a read-only filesystem, or
+ *	if #MDB_NOLOCK is set.
+ *
+ *	Since the database uses multi-version concurrency control, readers don't
+ *	actually need any locking. This table is used to keep track of which
+ *	readers are using data from which old transactions, so that we'll know
+ *	when a particular old transaction is no longer in use. Old transactions
+ *	that have discarded any data pages can then have those pages reclaimed
+ *	for use by a later write transaction.
+ *
+ *	The lock table is constructed such that reader slots are aligned with the
+ *	processor's cache line size. Any slot is only ever used by one thread.
+ *	This alignment guarantees that there will be no contention or cache
+ *	thrashing as threads update their own slot info, and also eliminates
+ *	any need for locking when accessing a slot.
+ *
+ *	A writer thread will scan every slot in the table to determine the oldest
+ *	outstanding reader transaction. Any freed pages older than this will be
+ *	reclaimed by the writer. The writer doesn't use any locks when scanning
+ *	this table. This means that there's no guarantee that the writer will
+ *	see the most up-to-date reader info, but that's not required for correct
+ *	operation - all we need is to know the upper bound on the oldest reader,
+ *	we don't care at all about the newest reader. So the only consequence of
+ *	reading stale information here is that old pages might hang around a
+ *	while longer before being reclaimed. That's actually good anyway, because
+ *	the longer we delay reclaiming old pages, the more likely it is that a
+ *	string of contiguous pages can be found after coalescing old pages from
+ *	many old transactions together.

+.SH NAME
+mdb_copy \- LMDB environment copy tool
+.SH SYNOPSIS
+.B mdb_copy
+[\c
+.BR \-V ]
+[\c
+.BR \-c ]
+[\c
+.BR \-n ]
+.B srcpath
+[\c
+.BR dstpath ]
+.SH DESCRIPTION
+The
+.B mdb_copy
+utility copies an LMDB environment. The environment can
+be copied regardless of whether it is currently in use.
+No lockfile is created, since it gets recreated at need.
+
+If
+.I dstpath
+is specified it must be the path of an empty directory
+for storing the backup. Otherwise, the backup will be
+written to stdout.
+
+.SH OPTIONS
+.TP
+.BR \-V
+Write the library version number to the standard output, and exit.
+.TP
+.BR \-c
+Compact while copying. Only current data pages will be copied; freed
+or unused pages will be omitted from the copy. This option will
+slow down the backup process as it is more CPU-intensive.
+Currently it fails if the environment has suffered a page leak.
+.TP
+.BR \-n
+Open LDMB environment(s) which do not use subdirectories.
+
+.SH DIAGNOSTICS
+Exit status is zero if no errors occur.
+Errors result in a non-zero exit status and
+a diagnostic message being written to standard error.
+.SH CAVEATS
+This utility can trigger significant file size growth if run
+in parallel with write transactions, because pages which they
+free during copying cannot be reused until the copy is done.
+.SH "SEE ALSO"
+.BR mdb_stat (1)

+.SH NAME
+mdb_dump \- LMDB environment export tool

+[\c
+.BR \-n ]

+.BI \-s \ subdb\fR]
+.BR \ envpath
+.SH DESCRIPTION
+The
+.B mdb_dump
+utility reads a database and writes its contents to the
+standard output using a portable flat-text format
+understood by the
+.BR mdb_load (1)
+utility.
+.SH OPTIONS
+.TP
+.BR \-V
+Write the library version number to the standard output, and exit.
+.TP
+.BR \-f \ file
+Write to the specified file instead of to the standard output.
+.TP
+.BR \-l
+List the databases stored in the environment. Just the
+names will be listed, no data will be output.
+.TP
+.BR \-n
+Dump an LMDB database which does not use subdirectories.
+.TP
+.BR \-p
+If characters in either the key or data items are printing characters (as
+defined by isprint(3)), output them directly. This option permits users to
+use standard text editors and tools to modify the contents of databases.
+
+Note: different systems may have different notions about what characters
+are considered printing characters, and databases dumped in this manner may
+be less portable to external systems. 
+.TP
+.BR \-a
+Dump all of the subdatabases in the environment.
+.TP
+.BR \-s \ subdb
+Dump a specific subdatabase. If no database is specified, only the main database is dumped.
+.SH DIAGNOSTICS
+Exit status is zero if no errors occur.
+Errors result in a non-zero exit status and
+a diagnostic message being written to standard error.
+
+Dumping and reloading databases that use user-defined comparison functions
+will result in new databases that use the default comparison functions.
+\fBIn this case it is quite likely that the reloaded database will be
+damaged beyond repair permitting neither record storage nor retrieval.\fP
+
+The only available workaround is to modify the source for the
+.BR mdb_load (1)
+utility to load the database using the correct comparison functions.

+.SH NAME
+mdb_load \- LMDB environment import tool
+.SH SYNOPSIS
+.B mdb_load
+[\c
+.BR \-V ]
+[\c
+.BI \-f \ file\fR]
+[\c
+.BR \-n ]
+[\c
+.BI \-s \ subdb\fR]
+[\c
+.BR \-N ]
+[\c
+.BR \-T ]
+.BR \ envpath
+.SH DESCRIPTION
+The
+.B mdb_load
+utility reads from the standard input and loads it into the
+LMDB environment
+.BR envpath .
+
+The input to
+.B mdb_load
+must be in the output format specified by the
+.BR mdb_dump (1)
+utility or as specified by the
+.B -T
+option below.
+.SH OPTIONS
+.TP
+.BR \-V
+Write the library version number to the standard output, and exit.
+.TP
+.BR \-f \ file
+Read from the specified file instead of from the standard input.
+.TP
+.BR \-n
+Load an LMDB database which does not use subdirectories.
+.TP
+.BR \-s \ subdb
+Load a specific subdatabase. If no database is specified, data is loaded into the main database.
+.TP
+.BR \-N
+Don't overwrite existing records when loading into an already existing database; just skip them.
+.TP
+.BR \-T
+Load data from simple text files. The input must be paired lines of text, where the first
+line of the pair is the key item, and the second line of the pair is its corresponding
+data item.
+
+A simple escape mechanism, where newline and backslash (\\) characters are special, is
+applied to the text input. Newline characters are interpreted as record separators.
+Backslash characters in the text will be interpreted in one of two ways: If the backslash
+character precedes another backslash character, the pair will be interpreted as a literal
+backslash. If the backslash character precedes any other character, the two characters
+following the backslash will be interpreted as a hexadecimal specification of a single
+character; for example, \\0a is a newline character in the ASCII character set.
+
+For this reason, any backslash or newline characters that naturally occur in the text
+input must be escaped to avoid misinterpretation by
+.BR mdb_load . 
+
+.SH DIAGNOSTICS
+Exit status is zero if no errors occur.
+Errors result in a non-zero exit status and
+a diagnostic message being written to standard error.

+                           MUTT UCData Package 2.5
+                           -----------------------
+
+This is a package that supports ctype-like operations for Unicode UCS-2 text
+(and surrogates), case mapping, decomposition lookup, and provides a
+bidirectional reordering algorithm.  To use it, you will need to get the
+latest "UnicodeData-*.txt" (or later) file from the Unicode Web or FTP site.
+
+The character information portion of the package consists of three parts:
+
+  1. A program called "ucgendat" which generates five data files from the
+     UnicodeData-*.txt file.  The files are:
+
+     A. case.dat   - the case mappings.
+     B. ctype.dat  - the character property tables.
+     C. comp.dat   - the character composition pairs.
+     D. decomp.dat - the character decompositions.
+     E. cmbcl.dat  - the non-zero combining classes.
+     F. num.dat    - the codes representing numbers.
+
+  2. The "ucdata.[ch]" files which implement the functions needed to
+     check to see if a character matches groups of properties, to map between
+     upper, lower, and title case, to look up the decomposition of a
+     character, look up the combining class of a character, and get the number
+     value of a character.
+
+  3. The UCData.java class which provides the same API (with minor changes for
+     the numbers) and loads the same binary data files as the C code.
+
+A short reference to the functions available is in the "api.txt" file.
+
+Techie Details
+==============
+
+The "ucgendat" program parses files from the command line which are all in the
+Unicode Character Database (UCDB) format.  An additional properties file,
+"MUTTUCData.txt", provides some extra properties for some characters.
+
+The program looks for the two character properties fields (2 and 4), the
+combining class field (3), the decomposition field (5), the numeric value
+field (8), and the case mapping fields (12, 13, and 14).  The decompositions
+are recursively expanded before being written out.
+
+The decomposition table contains all the canonical decompositions.  This means
+all decompositions that do not have tags such as "<compat>" or "<font>".
+
+The data is almost all stored as unsigned longs (32-bits assumed) and the
+routines that load the data take care of endian swaps when necessary.  This
+also means that supplementary characters (>= 0x10000) can be placed in the
+data files the "ucgendat" program parses.
+
+The data is written as external files and broken into six parts so it can be
+selectively updated at runtime if necessary.
+
+The data files currently generated from the "ucgendat" program total about 56K
+in size all together.
+
+The format of the binary data files is documented in the "format.txt" file.
+
+==========================================================================
+
+                       The "Pretty Good Bidi Algorithm"
+                       --------------------------------
+
+This routine provides an alternative to the Unicode Bidi algorithm.  The
+difference is that this version of the PGBA does not handle the explicit
+directional codes (LRE, RLE, LRO, RLO, PDF).  It should now produce the same
+results as the Unicode BiDi algorithm for implicit reordering.  Included are
+functions for doing cursor motion in both logical and visual order.
+
+This implementation is provided to demonstrate an effective alternate method
+for implicit reordering.  To make this useful for an application, it probably
+needs some changes to the memory allocation and deallocation, as well as data
+structure additions for rendering.

+   bidi algorithm.
+
+4. Fixed a problem with text runs of the opposite direction of the string
+   surrounding a weak + neutral text run appearing in the wrong order in the

+                             -------------------
+
+
+####
+NOTE: This library has been customized for use with OpenLDAP. The character
+data tables are hardcoded into the library and the load/unload/reload
+functions are no-ops. Also, the MUTT API claimed to be compatible with
+John Cowan's library but its ucnumber behavior was broken. This has been
+fixed in the OpenLDAP release.
+
+By default, the implementation specific properties in MUTTUCData.txt are
+not incorporated into the OpenLDAP build. You can supply them to ucgendat
+and recreate uctable.h if you need them.

+-----------------------------------------------------------------------------
+
+void ucdata_load(char *paths, int masks)
+
+  This function initializes the UCData library by locating the data files in
+  one of the colon-separated directories in the `paths' parameter.  The data
+  files to be loaded are specified in the `masks' parameter as a bitwise
+  combination of the macros listed above.
+
+  This should be called before using any of the other functions.
+
+  NOTE: the ucdata_setup(char *paths) function is now a macro that expands
+        into this function at compile time.
+
+-----------------------------------------------------------------------------
+
+void ucdata_unload(int masks)
+
+  This function unloads the data tables specified in the `masks' parameter.
+
+  This function should be called when the application is done using the UCData
+  package.
+
+  NOTE: the ucdata_cleanup() function is now a macro that expands into this
+        function at compile time.
+
+-----------------------------------------------------------------------------
+
+void ucdata_reload(char *paths, int masks)
+
+  This function reloads the data files from one of the colon-separated
+  directories in the `paths' parameter.  The data files to be reloaded are
+  specified in the `masks' parameter as a bitwise combination of the macros
+  listed above.
+
+  If the data files have already been loaded, they are unloaded before the
+  data files are loaded again.
+
+-----------------------------------------------------------------------------
+
+int ucdecomp(unsigned long code, unsigned long *num, unsigned long **decomp)
+
+  This function determines if a character has a decomposition and returns the
+  decomposition information if it exists.
+
+  If a zero is returned, there is no decomposition.  If a non-zero is
+  returned, then the `num' and `decomp' variables are filled in with the
+  appropriate values.
+
+  Example call:
+
+    unsigned long i, num, *decomp;
+
+    if (ucdecomp(0x1d5, &num, &decomp) != 0) {
+       for (i = 0; i < num; i++)
+         printf("0x%08lX,", decomp[i]);
+       putchar('\n');
+    }
+
+int uccanondecomp(const unsigned long *in, int inlen, unsigned long **out,
+                  int *outlen)
+
+  This function decomposes an input string and does canonical reordering of
+  the characters at the same time.
+
+  If a -1 is returned, memory allocation was not successful.  If a zero is
+  returned, no decomposition occured.  Any other value means the output string
+  contains the fully decomposed string in canonical order.
+
+  If the "outlen" parameter comes back with a value > 0, then the string
+  returned in the "out" parameter needs to be deallocated by the caller. 
+
+-----------------------------------------------------------------------------
+
+int ucdecomp_hangul(unsigned long code, unsigned long *num,
+                    unsigned long decomp[])
+
+  This function determines if a Hangul syllable has a decomposition and
+  returns the decomposition information.
+
+  An array of at least size 3 should be passed to the function for the
+  decomposition of the syllable.
+
+  If a zero is returned, the character is not a Hangul syllable.  If a
+  non-zero is returned, the `num' field will be 2 or 3 and the syllable will
+  be decomposed into the `decomp' array arithmetically.
+
+  Example call:
+
+    unsigned long i, num, decomp[3];
+
+    if (ucdecomp_hangul(0xb1ba, &num, &decomp) != 0) {
+       for (i = 0; i < num; i++)
+         printf("0x%08lX,", decomp[i]);
+       putchar('\n');
+    }
+
+-----------------------------------------------------------------------------
+
+int uccomp(unsigned long ch1, unsigned long ch2, unsigned long *comp)
+
+  This function takes a pair of characters and determines if they combine to
+  form another character.
+
+  If a zero is returned, no composition is formed by the character pair.  Any
+  other value indicates the "comp" parameter has a value.
+
+int uccomp_hangul(unsigned long *str, int len)
+
+  This function composes the Hangul Jamo in the string.  The composition is
+  done in-place.
+
+  The return value provides the new length of the string.  This will be
+  smaller than "len" if compositions occured.
+
+int uccanoncomp(unsigned long *str, int len)
+
+  This function does a canonical composition of characters in the string.
+
+  The return value is the new length of the string.
+
+-----------------------------------------------------------------------------
+
+struct ucnumber {
+  int numerator;
+  int denominator;
+};
+
+int ucnumber_lookup(unsigned long code, struct ucnumber *num)
+
+  This function determines if the code is a number and fills in the `num'
+  field with the numerator and denominator.  If the code happens to be a
+  single digit, the denominator field will be 1.
+
+####
+The original code would set numerator = denominator for regular digits.
+However, the Readme also claimed to be compatible with John Cowan's uctype
+library, but this behavior is both nonsensical and incompatible with the
+Cowan library. As such, it has been fixed here as described above.

+                       "Pretty Good Bidi Algorithm" API
+
+The PGBA (Pretty Good Bidi Algorithm) is an effective alternative to the
+Unicode BiDi algorithm.  It currently provides only implicit reordering and
+does not yet support explicit reordering codes that the Unicode BiDi algorithm
+supports.  In addition to reordering, the PGBA includes cursor movement
+support for both visual and logical navigation.

+#define UCPGBA_RTL 1
+
+  These macros appear in the `direction' field of the data structures.
+
+#define UCPGBA_CURSOR_VISUAL  0
+#define UCPGBA_CURSOR_LOGICAL 1
+
+  These macros are used to set the cursor movement for each reordered string.

+                            int cursor_motion)
+
+  This function will create a reordered string by using the implicit
+  directionality of the characters in the specified substring.
+
+  The `default_direction' parameter should be one of UCPGBA_LTR or UCPGBA_RTL
+  and is used only in cases where a string contains no characters with strong
+  directionality.
+
+  The `cursor_motion' parameter should be one of UCPGBA_CURSOR_VISUAL or

+  behavior.  This behavior can be switched at any time using
+  ustring_set_cursor_motion().

+CHARACTER DATA
+==============
+
+This package generates some data files that contain character properties useful
+for text processing.
+
+CHARACTER PROPERTIES
+====================
+
+The first data file is called "ctype.dat" and contains a compressed form of
+the character properties found in the Unicode Character Database (UCDB).
+Additional properties can be specified in limited UCDB format in another file
+to avoid modifying the original UCDB.
+
+The following is a property name and code table to be used with the character
+data:
+
+NAME CODE DESCRIPTION
+---------------------
+Mn   0    Mark, Non-Spacing
+Mc   1    Mark, Spacing Combining
+Me   2    Mark, Enclosing

+No   5    Number, Other
+Zs   6    Separator, Space
+Zl   7    Separator, Line
+Zp   8    Separator, Paragraph
+Cc   9    Other, Control

+EN   30   European Number
+ES   31   European Number Separator
+ET   32   European Number Terminator
+AN   33   Arabic Number
+CS   34   Common Number Separator
+B    35   Block Separator
+S    36   Segment Separator
+WS   37   Whitespace
+ON   38   Other Neutrals
+Pi   47   Punctuation, Initial
+Pf   48   Punctuation, Final
+#
+# Implementation specific properties.
+#
+Cm   39   Composite
+Nb   40   Non-Breaking
+Sy   41   Symmetric (characters which are part of open/close pairs)
+Hd   42   Hex Digit
+Qm   43   Quote Mark
+Mr   44   Mirroring
+Ss   45   Space, Other (controls viewed as spaces in ctype isspace())
+Cp   46   Defined character
+
+The actual binary data is formatted as follows:
+
+  Assumptions: unsigned short is at least 16-bits in size and unsigned long
+               is at least 32-bits in size.
+
+    unsigned short ByteOrderMark
+    unsigned short OffsetArraySize
+    unsigned long  Bytes
+    unsigned short Offsets[OffsetArraySize + 1]
+    unsigned long  Ranges[N], N = value of Offsets[OffsetArraySize]
+
+  The Bytes field provides the total byte count used for the Offsets[] and
+  Ranges[] arrays.  The Offsets[] array is aligned on a 4-byte boundary and
+  there is always one extra node on the end to hold the final index of the
+  Ranges[] array.  The Ranges[] array contains pairs of 4-byte values
+  representing a range of Unicode characters.  The pairs are arranged in
+  increasing order by the first character code in the range.
+
+  Determining if a particular character is in the property list requires a
+  simple binary search to determine if a character is in any of the ranges
+  for the property.
+
+  If the ByteOrderMark is equal to 0xFFFE, then the data was generated on a
+  machine with a different endian order and the values must be byte-swapped.
+
+  To swap a 16-bit value:
+     c = (c >> 8) | ((c & 0xff) << 8)
+
+  To swap a 32-bit value:
+     c = ((c & 0xff) << 24) | (((c >> 8) & 0xff) << 16) |
+         (((c >> 16) & 0xff) << 8) | (c >> 24)
+
+CASE MAPPINGS
+=============
+
+The next data file is called "case.dat" and contains three case mapping tables
+in the following order: upper, lower, and title case.  Each table is in
+increasing order by character code and each mapping contains 3 unsigned longs
+which represent the possible mappings.
+
+The format for the binary form of these tables is:
+
+  unsigned short ByteOrderMark
+  unsigned short NumMappingNodes, count of all mapping nodes
+  unsigned short CaseTableSizes[2], upper and lower mapping node counts
+  unsigned long  CaseTables[NumMappingNodes]
+
+  The starting indexes of the case tables are calculated as following:
+
+    UpperIndex = 0;
+    LowerIndex = CaseTableSizes[0] * 3;
+    TitleIndex = LowerIndex + CaseTableSizes[1] * 3;
+
+  The order of the fields for the three tables are:
+
+    Upper case
+    ----------
+    unsigned long upper;
+    unsigned long lower;
+    unsigned long title;
+
+    Lower case
+    ----------
+    unsigned long lower;
+    unsigned long upper;
+    unsigned long title;
+
+    Title case
+    ----------
+    unsigned long title;
+    unsigned long upper;
+    unsigned long lower;
+
+  If the ByteOrderMark is equal to 0xFFFE, endian swapping is required in the
+  same way as described in the CHARACTER PROPERTIES section.
+
+  Because the tables are in increasing order by character code, locating a
+  mapping requires a simple binary search on one of the 3 codes that make up
+  each node.
+
+  It is important to note that there can only be 65536 mapping nodes which
+  divided into 3 portions allows 21845 nodes for each case mapping table.  The
+  distribution of mappings may be more or less than 21845 per table, but only
+  65536 are allowed.
+
+COMPOSITIONS
+============
+
+This data file is called "comp.dat" and contains data that tracks character
+pairs that have a single Unicode value representing the combination of the two
+characters.
+
+The format for the binary form of this table is:
+
+  unsigned short ByteOrderMark
+  unsigned short NumCompositionNodes, count of composition nodes
+  unsigned long  Bytes, total number of bytes used for composition nodes
+  unsigned long  CompositionNodes[NumCompositionNodes * 4]
+
+  If the ByteOrderMark is equal to 0xFFFE, endian swapping is required in the
+  same way as described in the CHARACTER PROPERTIES section.
+
+  The CompositionNodes[] array consists of groups of 4 unsigned longs.  The
+  first of these is the character code representing the combination of two
+  other character codes, the second records the number of character codes that
+  make up the composition (not currently used), and the last two are the pair
+  of character codes whose combination is represented by the character code in
+  the first field.
+
+DECOMPOSITIONS
+==============
+
+The next data file is called "decomp.dat" and contains the decomposition data
+for all characters with decompositions containing more than one character and
+are *not* compatibility decompositions.  Compatibility decompositions are
+signaled in the UCDB format by the use of the <compat> tag in the
+decomposition field.  Each list of character codes represents a full
+decomposition of a composite character.  The nodes are arranged in increasing
+order by character code.
+
+The format for the binary form of this table is:
+
+  unsigned short ByteOrderMark
+  unsigned short NumDecompNodes, count of all decomposition nodes
+  unsigned long  Bytes
+  unsigned long  DecompNodes[(NumDecompNodes * 2) + 1]
+  unsigned long  Decomp[N], N = sum of all counts in DecompNodes[]
+
+  If the ByteOrderMark is equal to 0xFFFE, endian swapping is required in the
+  same way as described in the CHARACTER PROPERTIES section.
+
+  The DecompNodes[] array consists of pairs of unsigned longs, the first of
+  which is the character code and the second is the initial index of the list
+  of character codes representing the decomposition.
+
+  Locating the decomposition of a composite character requires a binary search
+  for a character code in the DecompNodes[] array and using its index to
+  locate the start of the decomposition.  The length of the decomposition list
+  is the index in the following element in DecompNode[] minus the current
+  index.
+
+COMBINING CLASSES
+=================
+
+The fourth data file is called "cmbcl.dat" and contains the characters with
+non-zero combining classes.
+
+The format for the binary form of this table is:
+
+  unsigned short ByteOrderMark
+  unsigned short NumCCLNodes
+  unsigned long  Bytes
+  unsigned long  CCLNodes[NumCCLNodes * 3]
+
+  If the ByteOrderMark is equal to 0xFFFE, endian swapping is required in the
+  same way as described in the CHARACTER PROPERTIES section.
+
+  The CCLNodes[] array consists of groups of three unsigned longs.  The first
+  and second are the beginning and ending of a range and the third is the
+  combining class of that range.
+
+  If a character is not found in this table, then the combining class is
+  assumed to be 0.
+
+  It is important to note that only 65536 distinct ranges plus combining class
+  can be specified because the NumCCLNodes is usually a 16-bit number.
+
+NUMBER TABLE
+============
+
+The final data file is called "num.dat" and contains the characters that have
+a numeric value associated with them.
+
+The format for the binary form of the table is:
+
+  unsigned short ByteOrderMark
+  unsigned short NumNumberNodes
+  unsigned long  Bytes
+  unsigned long  NumberNodes[NumNumberNodes]
+  unsigned short ValueNodes[(Bytes - (NumNumberNodes * sizeof(unsigned long)))
+                            / sizeof(short)]
+
+  If the ByteOrderMark is equal to 0xFFFE, endian swapping is required in the
+  same way as described in the CHARACTER PROPERTIES section.
+
+  The NumberNodes array contains pairs of values, the first of which is the
+  character code and the second an index into the ValueNodes array.  The
+  ValueNodes array contains pairs of integers which represent the numerator
+  and denominator of the numeric value of the character.  If the character
+  happens to map to an integer, both the values in ValueNodes will be the
+  same.

+.br
+.TP 4
+.BR ucdata_load()
+This function initializes the UCData library by locating the data files in one
+of the colon-separated directories in the `paths' parameter.  The data files
+to be loaded are specified in the `masks' parameter as a bitwise combination
+of the macros listed above.
+.sp
+This should be called before using any of the other functions.
+.TP 4
+.BR ucdata_unload()
+This function unloads the data tables specified in the `masks' parameter.
+.sp
+This function should be called when the application is done using the UCData
+package.
+.TP 4
+.BR ucdata_reload()
+This function reloads the data files from one of the colon-separated
+directories in the `paths' parameter.  The data files to be reloaded are
+specified in the `masks' parameter as a bitwise combination of the macros
+listed above.
+.TP 4
+.BR ucdecomp()
+This function determines if a character has a decomposition and returns the
+decomposition information if it exists.
+.sp
+If a zero is returned, there is no decomposition.  If a non-zero is
+returned, then the `num' and `decomp' variables are filled in with the
+appropriate values.
+.sp
+Example call:
+.sp
+.nf
+    unsigned long i, num, *decomp;
+
+    if (ucdecomp(0x1d5, &num, &decomp) != 0) {
+       for (i = 0; i < num; i++)
+         printf("0x%08lX,", decomp[i]);
+       putchar('\n');
+    }
+.TP 4
+.BR uccanondecomp()
+This function will decompose a string, insuring the characters are in
+canonical order for comparison.
+.sp
+If a decomposed string is returned, the caller is responsible for deallocating
+the string.
+.sp
+If a -1 is returned, memory allocation failed.  If a zero is returned, no
+decomposition was done.  Any other value means a decomposition string was
+created and the values returned in the `out' and `outlen' parameters.
+.TP 4
+.BR ucdecomp_hangul()
+This function determines if a Hangul syllable has a
+decomposition and returns the decomposition information.
+.sp
+An array of at least size 3 should be passed to the function
+for the decomposition of the syllable.
+.sp
+If a zero is returned, the character is not a Hangul
+syllable. If a non-zero is returned, the `num' field
+will be 2 or 3 and the syllable will be decomposed into
+the `decomp' array arithmetically.
+.sp
+Example call:
+.sp
+.nf
+    unsigned long i, num, decomp[3];
+
+    if (ucdecomp_hangul(0xb1ba, &num, &decomp) != 0) {
+       for (i = 0; i < num; i++)
+         printf("0x%08lX,", decomp[i]);
+       putchar('\n');
+    }
+.TP 4
+.BR uccomp()
+This function determines if a pair of characters have a composition, and
+returns that composition if one exists.
+.sp
+A zero is returned is no composition exists for the character pair.  Any other
+value indicates the `comp' field holds the character code representing the
+composition of the two character codes.
+.TP 4
+.BR uccomp_hangul()
+This composes the Hangul Jamo in-place in the string.
+.sp
+The returned value is the new length of the string.
+.TP 4
+.BR uccanoncomp()
+This function does a full composition in-place in the string, including the
+Hangul composition.
+.sp
+The returned value is the new length of the string.
+.TP 4
+.BR ucnumber_lookup()
+This function determines if the code is a number and
+fills in the `num' field with the numerator and
+denominator.  If the code happens to be a single digit,
+the numerator and denominator fields will be the same.
+.sp
+If the function returns 0, the code is not a number.
+Any other return value means the code is a number.
+.TP 4
+.BR ucdigit_lookup()
+This function determines if the code is a digit and
+fills in the `digit' field with the digit value.
+.sp
+If the function returns 0, the code is not a number.
+Any other return value means the code is a number.
+.TP 4
+.BR ucgetnumber()
+This is a compatibility function with John Cowan's
+"uctype" package.  It uses ucnumber_lookup().
+.TP 4
+.BR ucgetdigit()
+This is a compatibility function with John Cowan's
+"uctype" package.  It uses ucdigit_lookup().
+.TP 4
+.BR uctoupper()
+This function returns the code unchanged if it is
+already upper case or has no upper case equivalent.
+Otherwise the upper case equivalent is returned.
+.TP 4
+.BR uctolower()
+This function returns the code unchanged if it is
+already lower case or has no lower case equivalent.
+Otherwise the lower case equivalent is returned.
+.TP 4
+.BR uctotitle()
+This function returns the code unchanged if it is
+already title case or has no title case equivalent.
+Otherwise the title case equivalent is returned.

+UCPGBA_CURSOR_LOGICAL
+
+.TP 4
+.BR ucstring_create()
+This function will create a reordered string by using the implicit
+directionality of the characters in the specified substring.
+.sp
+The `default_direction' parameter should be one of UCPGBA_LTR or UCPGBA_RTL
+and is used only in cases where a string contains no characters with strong
+directionality.
+.sp
+The `cursor_motion' parameter should be one of UCPGBA_CURSOR_VISUAL or
+UCPGBA_CURSOR_LOGICAL, and is used to specify the initial cursor motion
+behavior.  This behavior can be switched at any time using
+ustring_set_cursor_motion().
+
+.TP 4
+.BR ucstring_free()
+This function will deallocate the memory used by the string, incuding the
+string itself.
+
+.TP 4
+.BR ucstring_cursor_info()
+This function will return the text position of the internal cursor and the
+directionality of the text at that position.  The position returned is the
+original text position of the character.
+
+.TP 4
+.BR ucstring_set_cursor_motion()
+This function will change the cursor motion type and return the previous
+cursor motion type.
+
+.TP 4
+.BR ucstring_cursor_right()
+This function will move the internal cursor to the right according to the
+type of cursor motion set for the string.
+.sp
+If no cursor motion is performed, it returns 0.  Otherwise it will return a 1.
+
+.TP 4
+.BR ucstring_cursor_left()
+This function will move the internal cursor to the left according to the
+type of cursor motion set for the string.
+.sp
+If no cursor motion is performed, it returns 0.  Otherwise it will return a 1.

+                       Unicode and Regular Expressions
+                                 Version 0.5
+
+This is a simple regular expression package for matching against Unicode text
+in UCS2 form.  The implementation of this URE package is a variation on the
+RE->DFA algorithm done by Mark Hopkins (markh@csd4.csd.uwm.edu).  Mark
+Hopkins' algorithm had the virtue of being very simple, so it was used as a
+model.
+
+---------------------------------------------------------------------------
+
+Assumptions:
+
+  o  Regular expression and text already normalized.
+
+  o  Conversion to lower case assumes a 1-1 mapping.
+
+Definitions:
+
+  Separator - any one of U+2028, U+2029, '\n', '\r'.
+
+Operators:
+  .   - match any character.
+  *   - match zero or more of the last subexpression.
+  +   - match one or more of the last subexpression.
+  ?   - match zero or one of the last subexpression.
+  ()  - subexpression grouping.
+
+  Notes:
+
+    o  The "." operator normally does not match separators, but a flag is
+       available for the ure_exec() function that will allow this operator to
+       match a separator.
+
+Literals and Constants:
+
+  c       - literal UCS2 character.
+  \x....  - hexadecimal number of up to 4 digits.
+  \X....  - hexadecimal number of up to 4 digits.
+  \u....  - hexadecimal number of up to 4 digits.
+  \U....  - hexadecimal number of up to 4 digits.
+
+Character classes:
+
+  [...]           - Character class.
+  [^...]          - Negated character class.
+  \pN1,N2,...,Nn  - Character properties class.
+  \PN1,N2,...,Nn  - Negated character properties class.
+
+  POSIX character classes recognized:
+
+    :alnum:
+    :alpha:
+    :cntrl:
+    :digit:
+    :graph:
+    :lower:
+    :print:
+    :punct:
+    :space:
+    :upper:
+    :xdigit:
+
+  Notes:
+
+    o  Character property classes are \p or \P followed by a comma separated
+       list of integers between 1 and 32.  These integers are references to
+       the following character properties:
+
+        N	Character Property
+        --------------------------
+        1	_URE_NONSPACING
+        2	_URE_COMBINING
+        3	_URE_NUMDIGIT
+        4	_URE_NUMOTHER
+        5	_URE_SPACESEP
+        6	_URE_LINESEP
+        7	_URE_PARASEP
+        8	_URE_CNTRL
+        9	_URE_PUA
+        10	_URE_UPPER
+        11	_URE_LOWER
+        12	_URE_TITLE
+        13	_URE_MODIFIER
+        14	_URE_OTHERLETTER
+        15	_URE_DASHPUNCT
+        16	_URE_OPENPUNCT
+        17	_URE_CLOSEPUNCT
+        18	_URE_OTHERPUNCT
+        19	_URE_MATHSYM
+        20	_URE_CURRENCYSYM
+        21	_URE_OTHERSYM
+        22	_URE_LTR
+        23	_URE_RTL
+        24	_URE_EURONUM
+        25	_URE_EURONUMSEP
+        26	_URE_EURONUMTERM
+        27	_URE_ARABNUM
+        28	_URE_COMMONSEP
+        29	_URE_BLOCKSEP
+        30	_URE_SEGMENTSEP
+        31	_URE_WHITESPACE
+        32	_URE_OTHERNEUT
+
+    o  Character classes can contain literals, constants, and character
+       property classes. Example:
+
+       [abc\U10A\p1,3,4]
+
+---------------------------------------------------------------------------
+
+Before using URE
+----------------
+Before URE is used, two functions need to be created.  One to check if a
+character matches a set of URE character properties, and one to convert a
+character to lower case.
+
+Stubs for these function are located in the urestubs.c file.
+
+Using URE
+---------
+
+Sample pseudo-code fragment.
+
+  ure_buffer_t rebuf;
+  ure_dfa_t dfa;
+  ucs2_t *re, *text;
+  unsigned long relen, textlen;
+  unsigned long match_start, match_end;
+
+  /*
+   * Allocate the dynamic storage needed to compile regular expressions.
+   */
+  rebuf = ure_buffer_create();
+
+  for each regular expression in a list {
+      re = next regular expression;
+      relen = length(re);
+
+      /*
+       * Compile the regular expression with the case insensitive flag
+       * turned on.
+       */
+      dfa = ure_compile(re, relen, 1, rebuf);
+
+      /*
+       * Look for the first match in some text.  The matching will be done
+       * in a case insensitive manner because the expression was compiled
+       * with the case insensitive flag on.
+       */
+      if (ure_exec(dfa, 0, text, textlen, &match_start, &match_end))
+        printf("MATCH: %ld %ld\n", match_start, match_end);
+
+      /*
+       * Look for the first match in some text, ignoring non-spacing
+       * characters.
+       */
+      if (ure_exec(dfa, URE_IGNORE_NONSPACING, text, textlen,
+                   &match_start, &match_end))
+        printf("MATCH: %ld %ld\n", match_start, match_end);
+
+      /*
+       * Free the DFA.
+       */
+      ure_free_dfa(dfa);

+
+  /*

+                       Unicode and Boyer-Moore Searching
+                                 Version 0.2
+
+UTBM (Unicode Tuned Boyer-Moore) is a simple package that provides tuned
+Boyer-Moore searches on Unicode UCS2 text (handles high and low surrogates).
+
+---------------------------------------------------------------------------
+
+Assumptions:
+
+  o  Search pattern and text already normalized in some fasion.
+
+  o  Upper, lower, and title case conversions are one-to-one.
+
+  o  For conversions between upper, lower, and title case, UCS2 characters
+     always convert to other UCS2 characters, and UTF-16 characters always
+     convert to other UTF-16 characters.
+
+Flags:
+
+  UTBM provides three processing flags:
+
+  o  UTBM_CASEFOLD          - search in a case-insensitive manner.
+
+  o  UTBM_IGNORE_NONSPACING - ignore non-spacing characters in the pattern and
+                              the text.
+
+  o  UTBM_SPACE_COMPRESS    - view as a *single space*, sequential groups of
+                              U+2028, U+2029, '\n', '\r', '\t', and any
+                              character identified as a space by the Unicode
+                              support on the platform.
+
+                              This flag also causes all characters identified
+                              as control by the Unicode support on the
+                              platform to be ignored (except for '\n', '\r',
+                              and '\t').
+
+---------------------------------------------------------------------------
+
+Before using UTBM
+-----------------
+Before UTBM is used, some functions need to be created.  The "utbmstub.c" file
+contains stubs that need to be rewritten so they work with the Unicode support
+on the platform on which this package is being used.
+
+Using UTBM
+----------
+
+Sample pseudo-code fragment.
+
+  utbm_pattern_t pat;
+  ucs2_t *pattern, *text;
+  unsigned long patternlen, textlen;
+  unsigned long flags, match_start, match_end;
+
+  /*
+   * Allocate the dynamic storage needed for a search pattern.
+   */
+  pat = utbm_create_pattern();
+
+  /*
+   * Set the search flags desired.
+   */
+  flags = UTBM_CASEFOLD|UTBM_IGNORE_NONSPACING;
+
+  /*
+   * Compile the search pattern.
+   */
+  utbm_compile(pattern, patternlen, flags, pat);
+
+  /*
+   * Find the first occurance of the search pattern in the text.
+   */
+  if (utbm_exec(pat, text, textlen, &match_start, &match_end))
+    printf("MATCH: %ld %ld\n", match_start, match_end);
+
+  /*
+   * Free the dynamic storage used for the search pattern.
+   */
+  ure_free_pattern(pat);

+/* (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
