thanks for the response, I got it working with -noshell, I am looking for
more info on the .app option.
Can someone give me an example on passing arguments using the -s option?
The docs are as clear on the actual syntax.

I have a function start(Port, Htdocs) that I want to call with 8888,
"C:/htdocs" and I can't figure out what the appropriate syntax should be.
