+	  VOLK is the Vector-Optimized Library of Kernels. It is a
+	  library that contains kernels of hand-written SIMD code
+	  for different mathematical operations. Since each SIMD
+	  architecture can be very different and no compiler has yet
+	  come along to handle vectorization properly or highly
+	  efficiently, VOLK approaches the problem differently.
+
+	  For each architecture or platform that a developer wishes
+	  to vectorize for, a new proto-kernel is added to VOLK. At
+	  runtime, VOLK will select the correct proto-kernel. In this
+	  way, the users of VOLK call a kernel for performing the
+	  operation that is platform/architecture agnostic. This
+	  allows us to write portable SIMD code.
