+# 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:

+
+    - Modified
+        - to correct extreme right and extreme bottom behavior,
+        - to stay inside the screen whenever the tooltip might go out on
+          the top but still the screen is higher than the tooltip,
+        - to use the more flexible mouse positioning,
+        - to add customizable background color, padding, waittime and
+          wraplength on creation
