+    Demo of Notification integration with PySimpleGUI
+    
+    You will need to install the py-notifypy package (note spelling!):
+        pip install notify-py
+
+    Displays an OS created notification
+    
+    There are more options than those in this Demo... like all PySimpleGUI Demo Programs
+        the demo is meant to give you a starting point
+    
+    For more info about the notifypy package, visit the project's GitHub
+    https://github.com/ms7m/notify-py
+    
+    To show a notification, call the function provided: notify_popout
+    
+    If you use a base64 icon, then a temp file will be created. If you wish to cleanup these
+    temp files (an optional step), then include this line of code when you close the window:
+    [os.remove(file) for file in notify_popout.temp_files] if hasattr(notify_popout, 'temp_files') else None
