//See the end of the script for adding more engines

/* Originally a hack by Peppe Bergqvist, based I believe on an even older script. I then developed the script to add a couple of more engines before rewriting again to get this version. I'm indebted to the userscripts.org community for help, suggestions and the occasional code snippet */

// 2006-03-22 v1.0 by norcimo http://www.norcimo.com/fun/greasemonkey/
/* Initial release

Includes options dialogue to choose which engines to display and set localised TLD
