+    Run a Flask app in production or development/debug from the command line
+
+    If you wish to run a Flask app with Python instead of the `flask run` command,
+    this code provides an easier way to decide if you want to run it in production
+    or debug mode.
+
+    Usage: 
+    python flaskserver.py dev        # runs with debug set to True
+    python flaskserver.py            # production mode
