# A script to keep my fucking meme downloads somewhat manageable
# The goal of this script is to comm two dirs (one on my android
# device and the other locally, then sort the new files into a new
# folder to then be uploaded to $social_network. Maybe a final option to
# move the images to the old folder after the upload is complete
# would be good too. And remvoing of (1) files.)
