str = version([request])
The version() function returns a string with the current version of JSUS itself, or the V8 engine, or a full copyright notice followed by both program versions. As a special case, an argument of 0 instead returns the endianness of the hardware as the letter "E" (big) or "e" (little endian). Otherwise, the JSUS version is returned for an argument of 1 or the V8 version for an argument of 2. The full copyright notice is returned for anything else (including an omitted argument or any error detected).
