+%description
+bclc is an open source, BSD/MIT dual 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.
+
+libclc is designed to be portable and extensible. To this end, it
+provides generic implementations of most library requirements,
+allowing the target to override the generic implementation at the
+granularity of individual functions.
+
+libclc currently supports the AMDGCN, and R600 and NVPTX targets, but
+support for more targets is welcome.
