+%description
+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. VOLK is a sub-project of GNU Radio.
