//BUILDING FOR WINDOWS/LINUX:

//Prerequisites: Must have Node, NPM, and Bower installed globally.
//This assumes you have a folder next to `scout-app` called `scout-app-build`.
//`scout-app-build` folder should contain:
//  * locales (folder)
//  * icudtl.dat
//  * nw.pak
//  * Scout-App.exe
// All of those are from NW.js 0.12.3, the .exe is a renamed version of
// nw.exe with a custom icon
