Command line args in OSX?

[urmane]

I use the following to test in linux:

./t-engine --flush-stdout -Mits -n -uTestD00d

but cannot make OSX do the same. I've tried variations on this:

open -a T-Engine.app --args --flush-stdout -Mits -n -uTestD00d

but no joy. Does anyone know how to pass args (especially module and username) on the command line in OSX ?
