# WHAT IS THIS?
# On wikipedia I copied and pasted there list of recursive acronyms
# e.g. GNU (GNUs not Unix) or YAML (YAML ain't Markup Language). Then
# I went to the internet and searched how to make text on a certain
# background with ffmpeg. Once I did that I ran it on all of the
# recursive acronyms. So a lot of 10 second videos. Then I concat them
# into just one, and then finally put on free none copyright music I
# found on invidious. This was inspired by Roel van de Par's videos of
# various stackexchange questions and answers he pumps out basicly
# every 5 minutes on his chanel.
