		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, th 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 poriginal
		119	uudeview).

		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 of measured in megabytes and buffer overflows as a security
		608	thign didn't exist. While a lot of security fixes have been applied over
		609	the years (includign 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
		616	Lastly, this module uses a very "C-like" interface, which means it doesn't
		617	protect you from invalid points as you might expect from "more perlish"
		618	modules - for example, accessing a file item object after callinbg
		619	C<CleanUp> will likely result in crashes, memory corruption, or worse.
