(* An application that loads json provided input and produces Lustre
2
3
Usage:
4
lustrei -vhdl myvhdl.json 
5
lustrei -scade myscademodel.json 
6
  will produce a lustre file that can be compiled and analyzed
7
8
VHDL is handled in a double way: as a backend and as an import language
9
In a first step, lustrei -vhdl -print myvhdl.json shall print the VHDL model in stdout
