  xorit [options] [input_file]

[input_file]
  An input file may be specified as the data to be hashed; if a file is not
  specified, input will be read from STDIN.

[options]
  -kf <file>     - key data is loaded from specified file
  -kd <string>   - key char-data specified directly from command line
  -ki <uint>     - designate starting key index (default=0)
  -o <file>      - output goes to file instead of stdout
  -a             - input-at-once; output written back over input;
                   stdin unsupported
  -buf <uint>    - size of file read/write buffer (default=102400)
  -q             - quiet; outputs only errors
  -?             - this help

NOTE: data specified on the command line should be quoted, especially when
      spaces exist
