+ The OpenCL API headers in this package are unified headers and are designed to work
+ with all released OpenCL versions. This differs from previous OpenCL API headers,
+ where version-specific API headers either existed in separate branches, or
+ in separate folders in a branch.
+
+ By default, the OpenCL API headers in this repository are for the latest OpenCL
+ version supported. To use these API headers to target a different OpenCL version,
+ an application may #define the preprocessor value CL_TARGET_OPENCL_VERSION before
+ including the OpenCL API headers. The CL_TARGET_OPENCL_VERSION is a three digit
+ decimal value representing the OpenCL API version.
