+provide a lightweight DSP library that does 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.")
