// * Use `app.js` to run your app without `sails lift`.
// * To start the server, run: `node app.js`.
// *
// * This is handy in situations where the sails CLI is not relevant or useful.
// *
// * For example:
// *   => `node app.js`
// *   => `forever start app.js`
// *   => `node debug app.js`
// *   => `modulus deploy`
// *   => `heroku scale`
// *
// *
// * The same command-line arguments are supported, e.g.:
// * `node app.js --silent --port=80 --prod`


// Ensure we're in the project directory, so relative paths work as expected
// no matter where we actually lift from.
