Options:
  -m|--master           stop everything at end-of-file of the next file argument
  -w|--write <path>     the read input data will be write in the <path> file
Inputs:
  -                     use stdin as input
  <path>                open and read the <path> file

$ ./xor fileA fileB fileC > resultfile

$ echo 'hello world!' | ./xor --master - /dev/urandom --write part1 > part2
$ ./xor part1 part2
hello world!

$ echo 'hello world!' | ./xor -m - /dev/urandom -w part1 /dev/urandom -w part2 > part3
$ ./xor part1 part2 part3
hello world!
$ ./xor part*
hello world!
