+ Front-end configuration app for the TempDataLogger project. This script
+ configures the logger to the current system time and date, with a user
+ defined logging interval.
+
+ The logging interval should be specified in milliseconds and is rounded to
+ a multiple of 500ms.
+
+ Usage:
+ python temp_log_config.py <Log_Interval>
+
+ Example:
+ python temp_log_config.py 500
+
+ Requires the pywinusb library (https://pypi.python.org/pypi/pywinusb/).
