		267	Load the given file and scan it for encoded contents. Optionally tag it

		269	is no longer necessary. If you are certain of the part number, you can
		270	specify it as the last argument.
		271

		294	The first file has number C<0>, and the series has no holes, so you can

		297
		298	This function has to walk the linear list of fils on each access, so

		578
		579	This module supports the perlmulticore standard (see
		580	L<http://perlmulticore.schmorp.de/> for more info) for the following
		581	functions - generally these are functions accessing the disk and/or using
		582	considerable CPU time:
		583
		584	LoadFile
		585	$item->decode
		586	$item->decode_temp
		587	$item->remove_temp
		588	$item->info
		589
		590	The perl interpreter will be reacquired/released on every callback
		591	invocation, so for performance reasons, callbacks should be avoided if
		592	that is costly.
		593
		594	Future versions might enable multicore support for more functions.
		595
		596	=head1 BUGS AND LIMITATIONS
		597
		598	The original uulib library this module uses was written at a time where
		599	main memory of measured in megabytes and buffer overflows as a security
		600	thign didn't exist. While a lot of security fixes have been applied over
		601	the years (includign some defense in depth mechanism that can shield
		602	against a lot of as-of-yet undetected bugs), using this library for
		603	security purposes requires care.
		604
		605	Likewise, file sizes when the uulib library was written were tiny compared
		606	to today, so do not expect this library to handle files larger than 2GB.
