| 30 | This is StormSiren a program inspired by the StormSiren application |
|---|
| 31 | written by Roy McManus <slorf/users_sourceforge_net>. Much like the |
|---|
| 32 | original StormSiren written by Roy McManus <slorf/users_sourceforge_net>, |
|---|
| 33 | this program is a simple script capable of scanning and providing |
|---|
| 34 | notifications of weather bulletins issued by the National |
|---|
| 35 | Weather Service. StormSiren supports a wide range of paging devices |
|---|
| 36 | and filtering of alert types per alert device. While inspired by |
|---|
| 37 | StormSiren, StormSiren is a complete rewrite that is capable of using |
|---|
| 38 | the new CAP/XML feeds provided at http://www.weather.gov/alerts/. |
