      6 This posts data exactly as specified with no extra processing whatsoever.

      8 If you start the data with the letter @, the rest should be a filename.  Data
      9 is posted in a similar manner as --data does, except that newlines and
     10 carriage returns are preserved and conversions are never done.

     12 Like --data the default content-type sent to the server is
     13 application/x-www-form-urlencoded. If you want the data to be treated as
     14 arbitrary binary data by the server then set the content-type to octet-stream:
     15 -H "Content-Type: application/octet-stream".
     16 
     17 If this option is used several times, the ones following the first will append
     18 data as described in --data.
