   5 #    A tool to read quad-data input and generate a
   6 #    c test-program to help testing PKE/GIF, etc.
   7 #
   8 #    To Invoke:
   9 #       c_gen  <input_data_file> <output_c_file>
  10 #
  11 #    Expected input format:
  12 #       <first column> <second_column> <third column> <forth column>
  13 #       (indicator )    ( quad_word  )  ( source_addr)   (flag)
  14 #       -------------  ---------------  -------------- -------------
  15 #         n (for data)   0xH_H_H_H         0xH           4-CHARs
  16 #         ? (for test)   0xH  (addr)       0xH  (value)  0xH (mask)
  17 #         ! (reg wrt 32) 0xH  (addr)       0xH  (data)
  18 #         ~ (reg wrt 64) 0xH  (addr)       0xHigh_Low (data)
  19 #         % (reg read 64) 0xH (addr)       0xHigh_Low (data)
  20 #         @ (read only)  0xH  (addr)       4/8
  21 #         # comment line
  22 #       Note: n can be 0 (for VU1), 1 (for VU2), or 2 (for GIF).
  23 #             H, High, or Low is hex data in the format of FFFFFFFF
  24 #
  25 #
  26 #    Result output:
  27 #       A c file, either with the name specified, or default.c
