#!/bin/bash

# 1. PUT THIS SCRIPT IN YOUR APP's RES folder, for example /Users/myname/Developer/MyAndroidProject/app/src/main/res

# 2. UPDATE THIS VARIABLE to point to your local clone of https://github.com/google/material-design-icons
# if you don't alread have it git clone git@github.com:google/material-design-icons.git
basefolder="/Users/myname/Developer/material-design-icons"
