		201
		202	=head2 Initializing and cleanup
		203
		204	Initialize is automatically called when the module is loaded and allocates
		205	quite a small amount of memory for todays machines ;) CleanUp releases that
		206	again.
		207
		208	On my machine, a fairly complete decode with DBI backend needs about 10MB
		209	RSS to decode 20000 files.
		210
		211	=over
		212
		213	=item CleanUp
		214
		215	Release memory, file items and clean up files. Should be called after a
		216	decoidng run, if you want to start a new one.

		255
		256	=over
		257
		258	=item ($retval, $count) = LoadFile $fname, [$id, [$delflag, [$partno]]]
		259
		260	Load the given file and scan it for encoded contents. Optionally tag it
		261	with the given id, and if C<$delflag> is true, delete the file after it
		262	is no longer necessary. If you are certain of the part number, you can
		263	specify it as the last argument.
		264
		265	A better (usually faster) way of doing this is using the C<SetFNameFilter>
		266	functionality.
		267
		268	=item $retval = Smerge $pass
		269
		270	If you are desperate, try to call C<Smerge> with increasing C<$pass>
		271	values, beginning at C<0>, to try to merge parts that usually would not
		272	have been merged.
		273
		274	Most probably this will result in garbled files, so never do this by
		275	default, except:
		276
		277	If the C<OPT_AUTOCHECK> option has been disabled (by default it is
		278	enabled) to speed up file loading, then you I<have> to call C<Smerge -1>
		279	after loading all files as an additional pre-pass (which is normally done
		280	by C<LoadFile>).
		281
		282	=item $item = GetFileListItem $item_number
		283
		284	Return the C<$item> structure for the C<$item_number>'th found file, or
		285	C<undef> of no file with that number exists.
		286
		287	The first file has number C<0>, and the series has no holes, so you can
		288	iterate over all files by starting with zero and incrementing until you
		289	hit C<undef>.
		290
		291	This function has to walk the linear list of fils on each access, so
		292	if you want to iterate over all items, it is usually faster to use
		293	C<GetFileList>.
		294
		295	=item @items = GetFileList
		296
		297	Similar to C<GetFileListItem>, but returns all files in one go, which is
		298	very much faster for large number of items, and has no drawbacks when used
		299	for a small number of items.

		407
		408	Returns the message level as a string.
		409
		410	=item SetFileNameCallback $cb
		411
		412	Sets (or queries) the FileNameCallback, which is called whenever the
		413	decoding library can't find a filename and wants to extract a filename
		414	from the subject line of a posting. The callback will be called with
		415	two arguments, the subject line and the current candidate for the
		416	filename. The latter argument can be C<undef>, which means that no
		417	filename could be found (and likely no one exists, so it is safe to also
		418	return C<undef> in this case). If it doesn't return anything (not even
		419	C<undef>!), then nothing happens, so this is a no-op callback:
		420
		421	sub cb {
		422	return ();
		423	}
		424
		425	If it returns C<undef>, then this indicates that no filename could be
		426	found. In all other cases, the return value is taken to be the filename.
		427
		428	This is a slightly more useful callback:
		429
		430	sub cb {
		431	return unless $_[1]; # skip "Re:"-plies et al.
		432	my ($subject, $filename) = @_;
		433	# if we find some *.rar, take it

		580	considerable CPU time:

201	ACT_COPYING ACT_DECODING ACT_ENCODING	582	LoadFile

207	FILE_NOBEGIN FILE_NODATA FILE_NOEND
208	FILE_OK FILE_READ FILE_TMPFILE
209
210	Message severity levels:
211
212	MSG_ERROR MSG_FATAL MSG_MESSAGE
213	MSG_NOTE MSG_PANIC MSG_WARNING
214
215	Options:
216

218	OPT_ENCEXT OPT_ERRNO OPT_FAST OPT_IGNMODE
219	OPT_IGNREPLY OPT_OVERWRITE OPT_PREAMB OPT_PROGRESS

231	QP_ENCODED XX_ENCODED UU_ENCODED
232
233	=head1 Exported functions
234
235	Initializing and cleanup (Initialize is automatically called when the
236	module is loaded and allocates quite a bit of memory. CleanUp releases
237	that again).
238
239	Initialize; # not normally necessary
240	CleanUp; # could be called at the end to release memory
241
242	Setting and querying options:
243
244	$option = GetOption OPT_xxx;
245	SetOption OPT_xxx, opt-value;
246
247	Error and action values => stringified:
248
249	$msg = straction ACT_xxx;
250	$msg = strerror RET_xxx;
251
252	Setting various callbacks:
253
254	SetMsgCallback [callback-function];
255	SetBusyCallback [callback-function];
256	SetFileCallback [callback-function];
257	SetFNameFilter [callback-function];
258
259	Call the currently selected FNameFilter:
260
261	$file = FNameFilter $file;
262
263	Loading sourcefiles, optionally fuzzy merge and start decoding:
264
265	($retval, $count) = LoadFile $fname, [$id, [$delflag]];
266	$retval = Smerge $pass;
267	$item = GetFileListItem $item_number;
268
269	The procedural interface is undocumented, use the following methods instead:
270
271	$retval = $item->rename($newname);
272	$retval = $item->decode_temp;	584	$item->decode_temp
273	$retval = $item->remove_temp;	585	$item->remove_temp
274	$retval = $item->decode([$target_path]);	586	$item->info
275	$retval = $item->info(callback-function);
276		587
277	Querying (and setting) item attributes:	588	The perl interpreter will be reacquired/released on every callback
		589	invocation, so for performance reasons, callbacks should be avoided if
		590	that is costly.
278		591
279	$state = $item->state;	592	Future versions might enable multicore support for more functions.
280	$mode = $item->mode([newmode]);
281	$uudet = $item->uudet;
282	$size = $item->size;
283	$filename = $item->filename([newfilename});
284	$subfname = $item->subfname;
285	$mimeid = $item->mimeid;
286	$mimetype = $item->mimetype;
287	$binfile = $item->binfile;

291	$parts = $item->parts;	596	The original uulib library this module uses was written at a time where
		597	main memory of measured in megabytes and buffer overflows as a security
		598	thign didn't exist. While a lot of security fixes have been applied over
		599	the years (includign some defense in depth mechanism that can shield
		600	against a lot of as-of-yet undetected bugs), using this library for
		601	security purposes requires care.
292		602
293	Functions below not documented and not very well tested:	603	Likewise, file sizes when the uulib library was written were tiny compared
		604	to today, so do not expect this library to handle files larger than 2GB.
