It does, yes. See the comment at the top of the file: It requires cscript.exe, which is more or less just the Windows Script Host.
I pointed out the script ostensibly because of the similarities of ES6 and TypeScript both having specs written in Word, and of a desire to convert into a much more web-friendly format. See specs.md: https://github.com/Microsoft/TypeScript/tree/master/doc
Speaking more honestly, I was being a bit tongue-in-cheek and trying to bounce certain eyes onto the TypeScript repo in the continued hopes that its transparent, optional, gradual type system be further considered for future versions of ES (such as 7...wink?)
