		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>

		270	If you are desperate, try to call C<Smerge> with increasing C<$pass>

		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

		290
		291	This function has to walk the linear list of fils on each access, so

		571
		572	This module supports the perlmulticore standard (see
		573	L<http://perlmulticore.schmorp.de/> for more info) for the following
		574	functions - generally these are functions accessing the disk and/or using
		575	considerable CPU time:
		576
		577	LoadFile
		578	$item->decode
		579	$item->decode_temp
		580	$item->remove_temp
		581	$item->info
		582
		583	The perl interpreter will be reacquired/released on every callback
		584	invocation, so for performance reasons, callbacks should be avoided if
		585	that is costly.
		586
		587	Future versions might enable multicore support for more functions.
		588
		589	=head1 BUGS AND LIMITATIONS
		590
		591	The original uulib library this module uses was written at a time where
		592	main memory of measured in megabytes and buffer overflows as a security
		593	thign didn't exist. While a lot of security fixes have been applied over
		594	the years (includign some defense in depth mechanism that can shield
		595	against a lot of as-of-yet undetected bugs), using this library for
		596	security purposes requires care.
		597
		598	Likewise, file sizes when the uulib library was written were tiny compared
		599	to today, so do not expect this library to handle files larger than 2GB.
