  rebuild a model_file from several input files.
Each input file contains the model_data for a domain.

Usage :
  ${b_n} [-h]
  ${b_n} [-v level] [-f] -o output_file_name input_file_names

Options :
  -h         : help
  -v O/1/2/3 : verbose mode (verbosity increasing with level)
  -f         : executing mode
               (execute the program even if the number of input files
                is not equal to the total number of domains)
