+/*! \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 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.
+ *
+ * \code
+ * #define __CL_ENABLE_EXCEPTIONS
