-/*! \mainpage
- * \section intro Introduction
- * For many large applications C++ is the language of choice and so it seems
- * reasonable to define C++ bindings for OpenCL.
- *
- * The interface is contained with a single C++ header file \em cl2.hpp and all
- * definitions are contained within the namespace \em cl. There is no additional
- * requirement to include \em cl.h and to use either the C++ or original C
- * bindings; it is enough to simply include \em cl2.hpp.
- *
- * The bindings themselves are lightweight and correspond closely to the
- * underlying C API. Using the C++ bindings introduces no additional execution
- * overhead.
- *
- * There are numerous compatibility, portability and memory management
- * fixes in the new header as well as additional OpenCL 2.0 features.
- * As a result the header is not directly backward compatible and for this
- * reason we release it as cl2.hpp rather than a new version of cl.hpp.
- *
- *
- * \section compatibility Compatibility
- * Due to the evolution of the underlying OpenCL API the 2.0 C++ bindings
- * include an updated approach to defining supported feature versions
- * and the range of valid underlying OpenCL runtime versions supported.
- *
- * The combination of preprocessor macros CL_HPP_TARGET_OPENCL_VERSION and
- * CL_HPP_MINIMUM_OPENCL_VERSION control this range. These are three digit
- * decimal values representing OpenCL runime versions. The default for
- * the target is 200, representing OpenCL 2.0 and the minimum is also
- * defined as 200. These settings would use 2.0 API calls only.
- * If backward compatibility with a 1.2 runtime is required, the minimum
- * version may be set to 120.
- *
- * Note that this is a compile-time setting, and so affects linking against
- * a particular SDK version rather than the versioning of the loaded runtime.
- *
- * The earlier versions of the header included basic vector and string
- * classes based loosely on STL versions. These were difficult to
- * maintain and very rarely used. For the 2.0 header we now assume
- * the presence of the standard library unless requested otherwise.
- * We use std::array, std::vector, std::shared_ptr and std::string
- * throughout to safely manage memory and reduce the chance of a
- * recurrance of earlier memory management bugs.
- *
- * These classes are used through typedefs in the cl namespace:
- * cl::array, cl::vector, cl::pointer and cl::string.
- * In addition cl::allocate_pointer forwards to std::allocate_shared
- * by default.
- * In all cases these standard library classes can be replaced with
- * custom interface-compatible versions using the CL_HPP_NO_STD_ARRAY,
- * CL_HPP_NO_STD_VECTOR, CL_HPP_NO_STD_UNIQUE_PTR and
- * CL_HPP_NO_STD_STRING macros.
- *
- * The OpenCL 1.x versions of the C++ bindings included a size_t wrapper
- * class to interface with kernel enqueue. This caused unpleasant interactions
- * with the standard size_t declaration and led to namespacing bugs.
- * In the 2.0 version we have replaced this with a std::array-based interface.
- * However, the old behaviour can be regained for backward compatibility
- * using the CL_HPP_ENABLE_SIZE_T_COMPATIBILITY macro.
- *
- * Finally, the program construction interface used a clumsy vector-of-pairs
- * design in the earlier versions. We have replaced that with a cleaner
- * vector-of-vectors and vector-of-strings design. However, for backward
- * compatibility old behaviour can be regained with the
- * CL_HPP_ENABLE_PROGRAM_CONSTRUCTION_FROM_ARRAY_COMPATIBILITY macro.
- *
- * In OpenCL 2.0 OpenCL C is not entirely backward compatibility with
- * earlier versions. As a result a flag must be passed to the OpenCL C
- * compiled to request OpenCL 2.0 compilation of kernels with 1.2 as
- * the default in the absence of the flag.
- * In some cases the C++ bindings automatically compile code for ease.
- * For those cases the compilation defaults to OpenCL C 2.0.
- * If this is not wanted, the CL_HPP_CL_1_2_DEFAULT_BUILD macro may
- * be specified to assume 1.2 compilation.
- * If more fine-grained decisions on a per-kernel bases are required
- * then explicit build operations that take the flag should be used.
- *
- *
- * \section parameterization Parameters
- * This header may be parameterized by a set of preprocessor macros.
- *
- * - CL_HPP_TARGET_OPENCL_VERSION
- *
- * Defines the target OpenCL runtime version to build the header
- * against. Defaults to 200, representing OpenCL 2.0.
- *
- * - CL_HPP_NO_STD_STRING
- *
- * Do not use the standard library string class. cl::string is not
- * defined and may be defined by the user before cl2.hpp is
- * included.
- *
- * - CL_HPP_NO_STD_VECTOR
- *
- * Do not use the standard library vector class. cl::vector is not
- * defined and may be defined by the user before cl2.hpp is
- * included.
- *
- * - CL_HPP_NO_STD_ARRAY
- *
- * Do not use the standard library array class. cl::array is not
- * defined and may be defined by the user before cl2.hpp is
- * included.
- *
- * - CL_HPP_NO_STD_UNIQUE_PTR
- *
- * Do not use the standard library unique_ptr class. cl::pointer and
- * the cl::allocate_pointer functions are not defined and may be
- * defined by the user before cl2.hpp is included.
- *
- * - CL_HPP_ENABLE_DEVICE_FISSION
- *
- * Enables device fission for OpenCL 1.2 platforms.
- *
- * - CL_HPP_ENABLE_EXCEPTIONS
- *
- * Enable exceptions for use in the C++ bindings header. This is the
- * preferred error handling mechanism but is not required.
- *
- * - CL_HPP_ENABLE_SIZE_T_COMPATIBILITY
- *
- * Backward compatibility option to support cl.hpp-style size_t
- * class. Replaces the updated std::array derived version and
- * removal of size_t from the namespace. Note that in this case the
- * new size_t class is placed in the cl::compatibility namespace and
- * thus requires an additional using declaration for direct backward
- * compatibility.
- *
- * - CL_HPP_ENABLE_PROGRAM_CONSTRUCTION_FROM_ARRAY_COMPATIBILITY
- *
- * Enable older vector of pairs interface for construction of
- * programs.
- *
- * - CL_HPP_CL_1_2_DEFAULT_BUILD
- *
- * Default to OpenCL C 1.2 compilation rather than OpenCL C 2.0
- * applies to use of cl::Program construction and other program
- * build variants.
- *
- *
- * \section example Example
- *
- * The following example shows a general use case for the C++
- * bindings, including support for the optional exception feature and
- * also the supplied vector and string classes, see following sections for
- * decriptions of these features.
