+not rely on a myriad of external dependencies or proprietary and otherwise
+cumbersome frameworks. All signal processing elements are designed to be
+flexible, scalable, and dynamic, including filters, filter design,
+oscillators, modems, synchronizers, complex mathematical operations, and much
+more.")
