# Title: GTK3 based logout manager
# Purpose: Primarily for fluxbox, this tool provides a graphical menu for various session control commands like shutdown, logout, and reboot
# History:
# Usage:
# This is a bit for reference, but also to provide myself a little shutdown options menu, like xfce4, because fluxbox doesn't really provide one.
# Reference:
# https://www.linuxquestions.org/questions/slackware-14/how-do-i-run-menu-and-logout-from-the-command-line-in-fluxbox-864919/

# Improve:
# read commands to execute from an ini file
# actually execute the commands
# far future: provide graphical way to change commands run
