		110
		111	This module started as an interface to the uulib/uudeview library by Frank
		112	Pilhofer that can be used to decode all kinds of usenet (and other)
		113	binary messages.
		114
		115	After upstream abondoned the project, the library was continuously bugfixed
		116	and improved in this module, with major focuses on security fixes,
		117	correctness and speed (that does not mean that this library is considered
		118	safe with untrusted data, but it surely is safer than the original
		119	uudeview).

		269
		270	Load the given file and scan it for encoded contents. Optionally tag it
		271	with the given id, and if C<$delflag> is true, delete the file after it
		272	is no longer necessary. If you are certain of the part number, you can
		273	specify it as the last argument.
		274
		275	A better (usually faster) way of doing this is using the C<SetFNameFilter>
		276	functionality.
		277
226	$retval = Smerge $pass;	278	=item $retval = Smerge $pass
		279
		280	If you are desperate, try to call C<Smerge> with increasing C<$pass>
		281	values, beginning at C<0>, to try to merge parts that usually would not
		282	have been merged.
		283
		284	Most probably this will result in garbled files, so never do this by
		285	default, except:
		286
		287	If the C<OPT_AUTOCHECK> option has been disabled (by default it is
		288	enabled) to speed up file loading, then you I<have> to call C<Smerge -1>
		289	after loading all files as an additional pre-pass (which is normally done
		290	by C<LoadFile>).

		295	C<undef> of no file with that number exists.
230		296
		297	The first file has number C<0>, and the series has no holes, so you can
		298	iterate over all files by starting with zero and incrementing until you
		299	hit C<undef>.
		300
		301	This function has to walk the linear list of fils on each access, so
		302	if you want to iterate over all items, it is usually faster to use
		303	C<GetFileList>.
		304
		305	=item @items = GetFileList
		306
		307	Similar to C<GetFileListItem>, but returns all files in one go, which is
		308	very much faster for large number of items, and has no drawbacks when used
		309	for a small number of items.

		586
		587	This module supports the perlmulticore standard (see
		588	L<http://perlmulticore.schmorp.de/> for more info) for the following
		589	functions - generally these are functions accessing the disk and/or using
		590	considerable CPU time:
		591
		592	LoadFile
		593	$item->decode
		594	$item->decode_temp
		595	$item->remove_temp
		596	$item->info
		597
		598	The perl interpreter will be reacquired/released on every callback
		599	invocation, so for performance reasons, callbacks should be avoided if
		600	that is costly.
		601
		602	Future versions might enable multicore support for more functions.
		603
		604	=head1 BUGS AND LIMITATIONS
		605
		606	The original uulib library this module uses was written at a time where
		607	main memory was measured in megabytes and buffer overflows as a security
		608	thing didn't exist. While a lot of security fixes have been applied over
		609	the years (including some defense in depth mechanism that can shield
		610	against a lot of as-of-yet undetected bugs), using this library for
		611	security purposes requires care.
		612
		613	Likewise, file sizes when the uulib library was written were tiny compared
		614	to today, so do not expect this library to handle files larger than 2GB,
		615	certainly not on a 32 bit host.
		616
		617	Lastly, this module uses a very "C-like" interface, which means it doesn't
		618	protect you from invalid pointers as you might expect from "more perlish"
		619	modules - for example, accessing a file item object after calling
		620	C<CleanUp> will likely result in crashes, memory corruption, or worse.
