+"""Python interface to Webthumb API (see http://bluga.net/webthumb/)
+
+By Ross Poulton - www.rossp.org
+
+License: Use this how you like, just don't claim it as your own because
+         that isn't cool. I'm not responsible for what this script does.
+
+Usage: Define WEBTHUMB_APIKEY with your API key, as per the above URL.
+
+Then, just call get_thumbnail(url, output_path). It will return true on
+success, false on anything else.
+
+An optional third parameter can be passed for the image size.
