get dependency tree

app.js

function init(config) {
  var util = require('app/util')
    , render = require('client/lib/render')
    , router = require('client/lib/router')
    , controllers = config.controllers
  
  controllers.forEach(function (c) {
    require(c)
  })
}

scripts.jade

head
  - var files = util.getDependencyTreeFiles('client/app')
  each file, i in files
    script(src=file)

Or you can do browserify main.js --list to print a list of newline-separated filenames.
