# Hi! If you're curious, this is a bash file. It's made to be run on bash, the
# "shell" of Linux (i.e. the program that turns command lines into machine
# instructions).
# If you're on Windows, try running "run.bat" instead.
# So yeah, I'm sorry, import is a Linux exclusive... though you can run
#     python3 ./src/import.py <url>
# as an alternative.
