print '''USAGE:
This tool finds duplicate Camera Uploads in your Dropbox. These are characterised by:
1) Having a name that looks like 2020.12.34 56.78.12-1.jpg (see the '-1' at the end)
2) Having exactly the same pixel content
This script searches from the current dir and calculates image difference (with PIL),
then outputs duplicate paths (the '-1' names) for which there is no difference with
the original (the file without '-1', IF it exists).
To delete duplicate images you can use this script like so:
$ ./ | xargs -t -I_ rm _
(I know, xargs is a piece of shit)
