appletouch is a Linux kernel driver for the USB touchpad found on post
February 2005 and October 2005 Apple Aluminium Powerbooks.
This driver is derived from Johannes Berg's appletrackpad driver[1], but it has
been improved in some areas:
This driver is derived from Johannes Berg's appletrackpad driver [#f1]_,
but it has been improved in some areas:
* appletouch is a full kernel driver, no userspace program is necessary
* appletouch can be interfaced with the synaptics X11 driver, in order
to have touchpad acceleration, scrolling, etc.
