+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:
address@hidden
address@hidden AVX and AVX2
address@hidden SSE2 upto SSE4.2 or SSE4a
address@hidden Scalar
address@hidden MIC
address@hidden NEON (in development)
address@hidden NVIDIA GPUs / CUDA (in development)
address@hidden enumerate\n")
