+VOLK is the Vector-Optimized Library of Kernels. It is a free library,
+currently offered under the GPLv3, 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 that is optimized for a variety of platforms.
+
+VOLK was introduced as a part of GNU Radio in late 2010 based on code released
+in the public domain. In 2015 it was released as an independent library for
+use by a wider audience.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
