The generate_binary.sh is a script that calls the objcopy tool and genpeimg in the case of Windows, to generate a PE binary file. But doesn't have to be a shell script and could be rewritten as a python script. This will make this code to generate a PE binary easier to extend if needed. Also, the only reason that's a template is to define the objcopy tool used, but this can also be passed as a positional argument.
