# compiling this is super easy, just run `pip install wget` and `pip install pyinstaller` and then
# compile with `python -m PyInstaller --onefile installer.py --icon image.ico`

# (wget is a dependency for this python script that doesnt come with python by default)
# (and pyinstaller is the packagey thingamajig that compiles the code into an executable.)

# also, peep the organized code blocks!! am i cool or what?

# something worthy of note: this code desperately needs to be refactored. right now literally
# everything important happens under a big if elif statement and its pretty fucking stupid

# idea! consolidate both delete things and add an extra option to the functions that toggles-
# -error outputs using an if statement in the function's code `if quiet = true then... else...`

# as far as i can tell, i wanted to add an "option" to the function that toggled the warning m-
# -essage, so i dont have to use all this space here defining functions i dont really need.
