AUTHOR: MANU\n
DESCRIPTION: This is a bash script for initiating Flask and Nile. Make sure that you have
MySQL installed locally on your machine. The server.py file requires a username and password.
This script checks if you have them as global environment variables. If not, the script will add
it locally. If your environment variables don't seem to be registering, restart your IDE or terminal."
