fix example command to include standard library path

[wweic]

This is a quick fix.

Maybe we should consider:

• add help doc to -I option
• add documentation on how to use the generated js to interoperate with other js code.

thanks, I am a bit interesting what is the error message when missing I ../stdlib, since I did follow it step by step, but did not find an error

This is a session in a new host:

The root cause is because https://github.com/ocaml/ocaml/blob/trunk/utils/misc.ml#L115 does NOT do recursive directory find. -I will append the path to Config.load_path.

I suspect you might have some paths in your .ocamlinit file.

[bobzhang]

ah, it's because you didn't create tmp dir

I see. The commands all depend on previous commands' state. I have to be inside stdlib. thanks. Closing for now.
