Node.js CLI hashbang under CoffeeScript? -

how preserve top-of-file hashbang when converting node.js cli coffeescript?

#! /usr/bin/env node <-- this?  try   require('./cli/main') process.argv  catch   require('./cli/error').err _error, true 

clarification: i'm looking emit javascript preserves hashbang is, not change hashbang use coffee, if makes sense.
