This driver has been written based on the xf86Elo.c code from the xfree86
It has been tested with an infra-red touchscreen using a serial
Elo / Carroltouch IR controller, and tested on Solaris 10 (Sparc),
Ubuntu Linux 9.04, Oracle Enterprise Linux 5 update 5.
The driver is designed to be run from the command line, primarily to it can
be used with a Sun Ray thin client. The Sun Ray X server does not load drivers
from the Xorg.conf file. The driver uses the XTest extension library, so you
will need to make sure this is installed. On Debian or Ubuntu, the package
you will need is 'libxtst-dev' to compile and 'libxtst6' to run.
Run 'elosetup' to create a calibration file for use with the driver.
