+This is a little script that retrieves weather information and prints it at the console.  No more bother of opening a web browswer!
+
+Usage: weather -[z,w] -[c,f] -e (optional) <zipcode || woeid>
+-[z.w] : use ZipCode (z) or WOEID (w)
+-[c,f] : units Celcius (c default) or Fahrenheit (f) 
+-e : print extended forcast information
+
+Requires:
+urllib2
