Calculating BLEU scores in Python

[Gribouillis]

If I understand well how the program works, you don't need any programming experience to use it as a black box:

1. Create a file machine-translated.txt containing the machine translation of some text.
   
2. Create a directory containing one or more human translations of the same text, say human-translated-1.txt, human-translated-2.txt etc.
   
3. Run the command python calculatebleu.py machine-translated.txt path-to-directory
   
4. Then read the contents of the new file bleu_output.txt
