		405
		406	=head2 OPENCL 1.1 VS. OPENCL 1.2
		407
		408	This module supports both OpenCL version 1.1 and 1.2, although the OpenCL
		409	1.2 interface hasn't been tested much for lack of availability of an
		410	actual implementation.
		411
		412	Every function or method in this manual page that interfaces to a
		413	particular OpenCL function has a link to the its C manual page.
		414
		415	If the link contains a F<1.1>, then this function is an OpenCL 1.1
		416	function. Most but not all also exist in OpenCL 1.2, and this module
		417	tries to emulate the missing ones for you, when told to do so at
		418	compiletime. You cna check whether a function was removed in OpenCL 1.2 by
		419	replacing the F<1.1> component in the URL by F<1.2>.
		420
		421	If the link contains a F<1.2>, then this is a OpenCL 1.2-only
		422	function. Even if the module was compiled with OpenCL 1.2 header files
		423	and has an 1.2 OpenCL library, calling such a function on a platform that
		424	doesn't implement 1.2 causes undefined behaviour, usually a crash (But
		425	this is not guaranteed).
		426
		427	You can find out whether this module was compiled to prefer 1.1
		428	functionality by ooking at C<OpenCL::PREFER_1_1> - if it is true, then
		429	1.1 functions generally are implemented using 1.1 OpenCL functions. If it
		430	is false, then 1.1 functions missing from 1.2 are emulated by calling 1.2
		431	fucntions.
		432
		433	This is a somewhat sorry state of affairs, but the Khronos group choose to
		434	make every release of OpenCL source and binary incompatible with previous
		435	releases.

438		476
		477	The OpenCL module converts all these callbacks into events - you can
		478	still register callbacks, but they are not executed when your OpenCL
		479	implementation calls the actual callback, but only later. Therefore, none
		480	of the limitations of OpenCL callbacks apply to the perl implementation:
