#! /bin/bash

# a shell script to make it easier to download images from google's
# material design icons project.
#
# usage:
# sh ~/material.sh -f ic_pause.png https://github.com/google/material-design-icons/blob/master/av/drawable-xxhdpi/ic_pause_white_24dp.png
# by default, it outputs to app/src/main/res/drawable-* in the current
# directory, but you can override with -o.
