gulp

gulp executes one single task: it reads scripts/main/app.js and calls browserify on it.

app.js defines an angular app and requires all the external modules injecting all requirements in the app.

all modules are defined through a _module_init.js file (e.g. initialize boilerplate.controllers module under /scripts/controllers folder) that both exports the angular module and requires all functions (e.g. controllers, directives, factories, etc.) defined in the same folder.

all functions defined for the angular module are importing the module itself using browserify's require and adding properties to it (e.g. /scripts/controllers/welcome.js)

there are a lot of things that I don't like in this boilerplate, but I think its main caveat is that using scripts/main/app.js as a single source in browserify does not let gulp execute lint/shim on singular js files. If anyone comes with a clever (and simple) solution to fix it, more than welcomed!
