Hi everybody,
I added screenshots for all the hierarchical flowgraphs and the top
flowgraph to the docs directory. I hope this helps to build the whole
LTE flowgraph in GRC.
Although, I realized that would be very helpful if the hierarchical
flowgraphs would be compiled with grcc during make and then installed.
Preferably added to a CMakeLists file. I will look into this.
Happy hacking
Johannes
