NAME ^

        TkWeather, by Jim Turner c. 2003, 2004, 2005, 2006, 2007, 2008

SYNOPSIS ^

        tkweather.pl [-options=values] [zip-code] [site]

DESCRIPTION ^

        This program displays a nice square iconic button showing the 
        current weather condition.  Clicking the button shows the current
        basic weather condition values, such as temperature, humidity, and 
        wind.  Clicking again shows additional information, namely the 
        barometric pressure, UV, visiblility, and "heat index" or 
        "wind chill" or "misery index".  
        Holding the [Shift] key while 
        clicking displays a webpage showing the detailed weather info. 
        Holding the [Ctrl] key while clicking changes to the next weather 
        site.  
        Holding the [Ctrl] key while right-clicking changes to the previous 
        weather site.
        Double-clicking or holding the [Alt] key while clicking refreshes the 
        data. 
        Holding the [Shift] and [Ctrl] keys simultainously while clicking 
        exits the program.
        
        For anyone not from Houston, Texas,
        the old "misery index" is the temperature plus dewpoint.  Anything 
        over 150 is considered "miserable"!  I use this for planning 
        workouts.  The default is to use the more modern "heat index".  
        Specify "index=misery" for the old Houston "misery index".  
        "wind chill" is used if the temperature is below 70 and wind 
        is >= 10mph regardless.

        "site", is currently 0: "weather.com" (weather.com) or 1: "wunderground"
        (www.wunderground.com), 2: NOAA, or 3: Weatherbug.  If it fails on 
        the selected one, it tries the next site.  The default is 0 
        (weather.com).  

CONFIGURATION ^

        How to set up:

        1)  This program fetches the current conditions every 15 
        minutes (900 seconds) from www.weather.com or 
        www.wunderground.com.  

        2)  Create a "tkweather" directory in your home directory.

        3)  You will also need to specify your zipcode either as the 
        command-line argument or add a "zipcode=yourzip" line in 
        $HOME/tkweather/tkweather.cfg
        Otherwise you get the weather at the author's zipcode!

        4)  The optional file:  $HOME/tkweather/tkweather.cfg takes the
        format (defaults shown below):  Any line starting with "#" is 
        ignored as a comment.

        perl interpreter.

        7)  To make this app appear in your AfterStep/Windowmaker "wharf", 
        add the following to your config file:
        *Wharf Tkwather - MaxSwallow "Tkweather" tkweather.pl &
