/*
 * 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 cl.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 cl.hpp.
 *
 * The bindings themselves are lightweight and correspond closely to the
 * underlying C API. Using the C++ bindings introduces no additional execution
 * overhead.
 *
 * For detail documentation on the bindings see:
 *
 * The OpenCL C++ Wrapper API 1.1 (revision 04)
 *  http://www.khronos.org/registry/cl/specs/opencl-cplusplus-1.1.pdf
 *
 * \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.
