 ===== Introduction =====
 I was using the .bashrc file when logged in as a user (from your home directory, type sudo nano .bashrc) to launch scripts upon the Raspberry Pi bootup. However, while this works, its has one really annoying issue. If you login from another place, say from SSH, then the script runs again, which isn't great for my application.

 When you boot/reboot your Raspberry Pi, this will now run the launcher.sh, and if necessary, output any errors in the logs folder.
