for a complete overview.
This is a fork of the original Python version of syRF, re-written from scratch in C++.
See BUILD.md.
Although this compiles natively and is able to generate a stand-alone application, it does not implement all the functionalities that the original Python version of syRF does, such as plotting constant gain/noise circles.
