Weather Script

[Christopher Moore]

Hello Listers,
A few days ago I posted a crude script for obtaining the current weather.
Below is a revised version which allows you to enter either a zipcode or
city, state.  The output is piped into the flite synthesizer.  If you don't
have flite you can remove the it and have the output sent to the console.
You can also change what info is spoken by modifying the awk program.
