# GUI for mouse wheel speed using imwheel in Gnome
# imwheel needs to be installed for this script to work
# For Arch and sub distributions
	# sudo pacman -S imwheel
# For Debian and sub distributions
	# sudo apt-get install imwheel
# Pretty much hard wired to only use a mouse with
# left, right and wheel in the middle.
# If you have a mouse with complications or special needs,
# use the command xev to find what your wheel does.
