# This script takes keyboard input and uses it to send events to the Kodi eventserver,
# it can be installed on any small pc like a Pi.
# To use an ordinary remote one could a Flirc.
# (the eventserver will be started automaticly when Kodi starts)
# It is assumed the keyboard is at /dev/input/event0
# The IP address connected to need to be adjusted to your Kodi installation
# The XBMCClient class is used and can be found in the official Kodi repo
# To get the evdev library you'll need pip: apt-get install python-pip python dev
# and install the library: pip install evdev
