   To create a special version of GetDP with a non-readable built-in formulation:
   1) suppress all formulation lines commented with '//'
   2) suppress all new line chars (emacs: M-% ^Q^J  )
   3) copy the long resulting char line in BlackBoxProString[]
   4) define the program and resolution names
   5) rebuild with 'make blackbox'
