# This is lt_presentation
# A simple system tray tool to send LogiTech Presenter events
# directly to the desired presentation tool.
#
# It wraps around Atril, xdotool and wmctrl and requires python-evdev
# to communicate with the Presenter.
#
# Xfce's Presentation Mode is automatically activated and reset whenever
# a presentation is active.
