This script adds firmware to the update-mirror. Note that this script will replace an already existing version if
it has the same version number.
Usage: $0 [-r] [-n] [-u] <firmware>
	-r	Release the firmware by changing the branch specific link to point to the new firmware
	-n	Set the rsync dry-run flag (WARNING: does not prevent the release link!)
	-u	rsync update-mirror to the update servers. use sync-firmware.sh if you want to do that later.
	firmware: The directory created by the site-ffhh/build.sh script
			for example: /home/gluon/firmware/0.8.5+exp20171028
			Must contain a single subdirectory named stable or experimental.
