Regarding the directory structure


After reading the tutorial on GNU, what I understand is that for writing
a new signal processing block, I have to write the required code and
place it in the appropriate directory structure and then follow the
normal building instructions.
My doubt is that if I am using an existing signal processing block and I
just need to write a new python script for joining them, then do I still
need to place the files in the directory structure given and build them
or just run the python script.
