 Once generated, the C++ code file can be compiled using your compiler of choice:
 
 ```
-$(CXX) -O3 input.cpp $(typon --cpp-flags) 
+$(CXX) -O3 $(typon --cpp-flags) input.cpp
 ```
 
 Currently, you'll get the best support with G++ 13.

 ## Test harness
 
 `cd` into the `trans` directory, set up your `.env` file (you can copy the `.env.example` file), and run `python3 test_runner.py`.
