+%description OpenCL-icd
+This package contains Mesa implementation of OpenCL - standard for
+cross-platform, parallel programming of modern processors found in
+personal computers, servers and handheld/embedded devices. OpenCL
+specification can be found on Khronos Group site:
+<http://www.khronos.org/opencl/>. Mesa implements OpenCL 1.1.
+
+The implementation is provided as an installable client driver (ICD)
+for use with the ocl-icd loader.

+%description OpenCL-icd -l pl.UTF-8
+Ten pakiet zawiera implementację Mesa standardu OpenCL - standardu
+wieloplatformowego, równoległego programowania nowoczesnych
+procesorów, jakie znajdują się w komputerach osobistych, serwerach
+oraz urządzeniach przenośnych/wbudowanych. Specyfikację OpenCL można
+znaleźć na stronie Khronos Group: <http://www.khronos.org/opencl/>.
+Mesa zawiera implementację OpenCL w wersji 1.1.
