What is the meaning of driller_path

[Mambaboy]

Hi, guys
When running the driller-afl(afl-cgc), it puzzles me very much that what parameter should I set for the varialbe driller_path, which means the the location of driller executable. Is that the run.py in the driller module?
And there is not a '-D' paremeter in "_start_afl_instance" function, to start an AFL instance, which belongs to Class Fuzzer in the Fuzzer module. That's so odd!
Can you give some information about this question? Thank you very much!
