gnuradio-companion [options] [flowgraphs]
GNU Radio is a free & open-source software development toolkit that provides signal processing blocks to implement software-defined radios and signal-processing systems. The GNU Radio applications themselves are generally known as "flowgraphs", which are a series of signal processing blocks connected together, thus describing a data flow.
gnuradio-companion is effectively a Python code-generation tool. When a flowgraph is "compiled" in GRC, it generates Python code that creates the desired GUI windows and widgets, and creates and connects the blocks in the flowgraph.
