Build a polyglot for Hello World Produce a text file that prints "Hello World!" in as many programming languages as possible when compiled/interpreted, while also being as short as possible.

The score for your submission is calculated as C / 2 ^ ((L - 1) / 4), where "C" is the length of the text file in characters and "L" is the number of languages that the program is valid in. Lowest score wins, of course.
