### IMPORTANT NOTE:
###
### The generation of future executable scripts is launched within a subshell (),
### placed at the working directory before running the code and calling MadGraph.
###
### This is necessary as MadGraph automatically creates a Python <-> Fortran
### translation file called "py.py" which needs to be written on disk.
