 - If the grammar has no self-embedding rules then you do not need to pass the
   stack limit parameter. However, if it does have self-embedding rules then you
   need to pass the stack limit parameter. We recommend starting with `5` and
   then increasing it if you need more complexity
 - To sanity-check that the automaton is generating inputs as expected you can use the `test` binary housed in `src/gramfuzz-mutator`
