"""
Some memes, made up of multiple boxes with a predefined reading order,
can be confusing or feel unnatural when used with right-to-left (RTL) languages.
This script takes a vertically symmetric meme and adjusts it for RTL reading.
Optionally, you can also mirror the images if it makes more sense after swapping the two vertical halves.
