"""Get weather data, process it, prepare graphs & text files and

This script does little more than call other modules in sequence to
get data from the weather station, process it, plot some graphs,
generate some text files and upload the results to a web site.

For more information on using ``pywws.hourly``, see
:doc:`../guides/hourlylogging`.
