+    Front-end configuration app for the TempDataLogger project. This script
+    configures the logger to the current system time and date, with a user

+
+    The logging interval should be specified in milliseconds and is rounded to
+    a multiple of 500ms.
+

+        python temp_log_config.py <Log_Interval>
+
+    Example:
+        python temp_log_config.py 500
