quick sync script for symbols

	#!/usr/bin/env python
	"""
	A quick sync script for symbols from NFS->S3

	We can't simply record the time our sync script ran and find all newer files
	since files with timestamps in the past may appear. So, keep track of all .txt
	index files that we encounter, and only sync files when there are additions
	to that set.
