 Script Automation
 =================
 The scripts assume the following:
-- An fstab entry for /dev/sda1 pointing to /mnt/usb-config
+- An fstab entry for /dev/sda1 pointing to /mnt/usb-update
 - Binary and scripts live in /home/pi/hdmi-switcher
 
-The usb-config script will naively look to see if /dev/sda1 exists. If it does, it mounts it and then copies over any files on the drive with names config.ini, video.mp4
+The usb-update script will naively look to see if /dev/sda1 exists. If it does, it mounts it and then copies over any files on the drive with names config.ini, video.mp4 to the cwd.

+In addition, it will update the software on the Pi. Unlike when config.ini and video.ini are copied, the software will always be extracted to /home/pi/hdmi-switcher (this is to stop me accidentally overwriting changes when I modify source code in /home/pi/hdmi-switcher-src)
