# Title: Tray icon for logout-manager
# Purpose: To show a tray icon for logout options
# History:
# Alternative version of a trayicon that depends on mktrayicon
# Usage:
# Reference:
# keyboard-leds-trayicons
# Improve:
# Dependencies:
# raw: mktrayicon, awk, xset
# devuan: mktrayicon, mawk | gawk, x11-xserver-utils
# Documentation:
# This script works just fine. I just want to learn how to do this in python, and have icons on the menu.
