worked perfectly on CPUs that now probably are used to drive
*watches*; a modern smartphone is many many times more powerful.

My question is why the hell you would invent something as painfully
terrible on the human as Cscript when Graffiti is know to be
entirely workable in real time on what is in the modern day a
trivial processor.
