Replace all local images references in HTML with base64 inline data, e.g. for HTML emails

	#!/bin/bash

	# Searches for <img src="localImage" alt="altText"/> in index.html and replaces with:
	# <img src="data:image/png;base64,..." alt="altText"/>
	# writes output to build/index.html

	mkdir -p build

	# awk is really awkward: does not accept regexp groups :(
	# I'll keep the () anyways for my mental health!
