   * \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 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 1.2 (revision 09)
   *  http://www.khronos.org/registry/cl/specs/opencl-cplusplus-1.2.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.
   *
