+data-parallel programming.  It is a library designed to ease explicit
+vectorization of C++ code.  Its types enable explicitly stating data-parallel
+operations on multiple values. The parallelism is therefore added via the type
+system.  Vc has an intuitive API and provides portability between different
+compilers and compiler versions as well as portability between different vector
+instruction sets. Thus, an application written with Vc can be compiled for:
+@enumerate
+@item AVX and AVX2
+@item SSE2 upto SSE4.2 or SSE4a
+@item Scalar
+@item MIC
+@item NEON (in development)
+@item NVIDIA GPUs / CUDA (in development)
+@end enumerate\n")
