HOWTO: Upgrade Raspberry Pi OS from Bullseye to Bookworm
### WARNING: READ CAREFULLY BEFORE ATTEMPTING ###
#
# Officially, this is not recommended. YMMV
# https://www.raspberrypi.com/news/bookworm-the-new-version-of-raspberry-pi-os/
#
# This mostly works if you are on 64bit. You are on your own if you are on 32bit or mixed 64/32bit
#
# Credit to anfractuosity and fgimenezm for figuring out additional details for kernels

/* So how does this work?
I'm using ANSI escape sequences to control the behavior of the terminal while
cat is outputting the text. I deliberately place these control sequences inside
comments so the C++ compiler doesn't try to treat them as code.*/

/*The commands in the fake code comment move the cursor to the left edge and
clear out the line, allowing the fake code to take the place of the real code.
And this explanation uses similar commands to wipe itself out too. */
