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.

	want to be able to run it from.  Make sure line 1 points to your

	add the following to your config file:
	*Wharf Tkwather - MaxSwallow "Tkweather" tkweather.pl &
