+%description libclc
+libclc is an open source, BSD licensed implementation of the library
+requirements of the OpenCL C programming language, as specified by the
+OpenCL 1.1 Specification. The following sections of the specification
+impose library requirements:
+
+ * 6.1: Supported Data Types
+ * 6.2.3: Explicit Conversions
+ * 6.2.4.2: Reinterpreting Types Using as_type() and as_typen()
+ * 6.9: Preprocessor Directives and Macros
+ * 6.11: Built-in Functions
+ * 9.3: Double Precision Floating-Point
+ * 9.4: 64-bit Atomics
+ * 9.5: Writing to 3D image memory objects
+ * 9.6: Half Precision Floating-Point
+
+libclc is intended to be used with the Clang compiler's OpenCL
+frontend.
+
+%description libclc -l pl.UTF-8
+libclc to mająca otwarte źródła, wydana na licencji BSD implementacja
+wymagań bibliotecznych języka programowania OpenCL C zgodna ze
+specyfikacją OpenCL 1.1. Wymagania biblioteczne wynikają z
+następujących sekcji specyfikacji:
+
+ * 6.1: obsługiwane typy danych
+ * 6.2.3: jawne konwersje
+ * 6.2.4.2: reinterpretacja typów przy użyciu as_type() i as_typen()
+ * 6.9: dyrektywy i makra preprocesora
+ * 6.11: funkcje wbudowane
+ * 9.3: arytmetyka zmiennoprzecinkowa podwójnej precyzji
+ * 9.4: 64-bitowe operacje atomowe
+ * 9.5: zapis do biektów obrazów 3D w pamięci
+ * 9.6: arytmetyka zmiennoprzecinkowa połówkowej precyzji
+
+libclc jest przeznaczona do używania z frontendem OpenCL kompilatora
+Clang.
