"""
This is StormSiren a program inspired by the StormSiren application
written by Roy McManus <slorf/users_sourceforge_net>.  Much like the
original StormSiren written by Roy McManus <slorf/users_sourceforge_net>,
this program is a simple script capable of scanning and providing
notifications of weather bulletins issued by the National
Weather Service.  StormSiren supports a wide range of paging devices
and filtering of alert types per alert device.  While inspired by
StormSiren, StormSiren is a complete rewrite that is capable of using
the new CAP/XML feeds provided at http://www.weather.gov/alerts/.

For more information there is see the README.TXT file located in the root
of this directory.
