Cakefile help. Need a better way than console.log.

Cakefile

{exec, spawn} = require 'child_process'

task 'test', 'Run Mocha tests', ->
  proc = spawn 'mocha', ['-R', 'spec', '--colors']
  proc.stdout.on 'data', (buffer) -> console.log buffer.toString()
  proc.stderr.on 'data', (buffer) -> console.error buffer.toString()
  proc.on 'exit', (status) ->
    process.exit(1) if status != 0
