# Rust is required because of the "meeseeks" dependency because it uses a Rust
# library for some reason. I'll start looking for alternatives so we don't have
# to worry about installing it in the future because that is not a small
# dependency.

# It's impossible to pass a command line parameter (-y) to a shell script being
# read through stdin, so this line downloads, runs, and removes that script.
