// This is a Grease Monkey user script.

//
// If you are reading this in firefox and have grease monkey installed
// then you should now be able to select "Install User Script..." from the
// tools menu.

//
// This script changes the value of the Music: field on
// http://www.livejournal.com/update.bml to your last played track from
// audioscrobblers provided XML feed
//
// eg my feed -> http://ws.audioscrobbler.com/rss/recent.php?user=XIXs
//
// It trys to use your LJ name as your scrobbler name by default, if you
// are not so lucky as to have the same username on both sites then there
// is a menu item added under Tools/User_Script_Commands/ to set it. This
// menu item is only available when you are on the
// http://www.livejournal.com/update.bml page with this script installed.
//
// If you don't get anything, check that you do have a recent list of tracks
// in your feed from scrobbler before complaining.

// This seems to be the way to have editable options?
