		14
		15	Here is a high level overview of OpenCL:
		16
		17	First you need to find one or more OpenCL::Platforms (kind of like
		18	vendors) - usually there is only one.
		19
		20	Each platform gives you access to a number of OpenCL::Device objects, e.g.
		21	your graphics card.
		22
		23	From a platform and some device(s), you create an OpenCL::Context, which is
		24	a very central object in OpenCL: Once you have a context you can create
		25	most other objects:
		26
		27	OpenCL::Program objects, which store source code and, after building for a
		28	specific device ("compiling and linking"), also binary programs. For each
		29	kernel function in a program you can then create an OpenCL::Kernel object
		30	which represents basically a function call with argument values.
		31
		32	OpenCL::Memory objects of various flavours: OpenCL::Buffers objects (flat
		33	memory areas, think arrays or structs) and OpenCL::Image objects (think 2d
		34	or 3d array) for bulk data and input and output for kernels.
		35
		36	OpenCL::Sampler objects, which are kind of like texture filter modes in
		37	OpenGL.
		38
		39	OpenCL::Queue objects - command queues, which allow you to submit memory
		40	reads, writes and copies, as well as kernel calls to your devices. They
		41	also offer a variety of methods to synchronise request execution, for
		42	example with barriers or OpenCL::Event objects.
		43
		44	OpenCL::Event objects are used to signal when something is complete.

		63	is, but at least it's free of charge:

		71	=head1 BASIC WORKFLOW
		72
		73	To get something done, you basically have to do this once (refer to the
		74	examples below for actual code, this is just a high-level description):
		75
		76	Find some platform (e.g. the first one) and some device(s) (e.g. the first
		77	device of the platform), and create a context from those.
		78
		79	Create program objects from your OpenCL source code, then build (compile)
		80	the programs for each device you want to run them on.
		81
		82	Create kernel objects for all kernels you want to use (surprisingly, these
		83	are not device-specific).
		84
		85	Then, to execute stuff, you repeat these steps, possibly resuing or
		86	sharing some buffers:
		87
		88	Create some input and output buffers from your context. Set these as
		89	arguments to your kernel.
		90
		91	Enqueue buffer writes to initialise your input buffers (when not
		92	initialised at creation time).
		93
		94	Enqueue the kernel execution.
		95
		96	Enqueue buffer reads for your output buffer to read results.
