// @name                del.icio.us Reader
// @namespace      		http://www.strongasanox.co.uk/greasemonkey
// @description       	Allows Google Reader items to be added to del.icio.us

// Adapted from Google Reader + del.icio.us (uses the 'nodeInserted' function from http://userscripts.org/scripts/show/7957).
// All bugs are mine, and not Jordan Brock's

// Version 1 (2007-08-07)
// 		When 'Add to del.icio.us' is clicked, a psuedo-window is opened allowing
//		the user to save the current item to their del.icio.us bookmarks.
// 		Stores/retrieves the user's del.icio.us username using GM_setValue/GM_getValue
//		@TODO put an overlay over the page before showing the iframe holder
//
// Version 1.1 (2007-08-09)
//		Overlay added behind the del.icio.us psuedo-window to 'grey out' the Google Reader
//		display.
//
// Version 2.0 (2007-12-18)
//		Overlay removed and no longer requires the user's del.icio.us username.
//		Now acts like the 'post to del.icio.us' bookmarklet for the currently-being-read item.
