Arch Linux

Description:
xf86-input-evdev is not a hard dependency of Xorg, as other
modules (like xf86-input-libinput)may also provide input support

In my view, were are two options:

* Add an provides definition to every package which provides input support, and let users choose at install time

* Delete xf86-input-evdev from depends and handle them manually (As we do
for the video drivers)

I'm in favour of the first option, because, unlike video drivers, you
can choose your input provider freely.
