Vows Parameters as Env variables

[Adduh]

Is there a possibility to set environment variables to auto-set parameters from vows particularly '-i' and '--xunit'?
The reason why I need this that is my setup with the istanbul code coverage tool.
atm in my package.json:
"test": "istanbul test which vows",

and istanbul doesn't take more parameters itself

vows 1.x uses yargs for handling parameters, and there's an option to take parameters from the environment. So, yeah, this is a good idea.
