+ "Pocl is a portable implementation of the OpenCL standard (1.2 with some
+2.0 features supported). This project seeks to improve performance
+portability of OpenCL programs with the kernel compiler and the task run-time,
+reducing the need for target-dependent manual optimizations.
+
+pocl uses Clang as an OpenCL C frontend and LLVM for kernel compiler
+implementation, and as a portability layer. Thus, if your desired target has
+an LLVM backend, it should be able to get OpenCL support easily by using
+pocl.")
