# Usage

addCode = require 'browserify-add-code'
app.use addCode browserify(), -> (require './client/app').init foo: true, bar: baz

# install() would patch browserify and add an addCode() method
(require 'browserify-add-code').install()
app.use browserify().addCode -> (require './client/app').init foo: true, bar: baz
