- * jquery.suggest 1.1b - 2007-08-06
- * Patched by Mark Jaquith with Alexander Dick's "multiple items" patch to allow for auto-suggesting of more than one tag before submitting
- * See: http://www.vulgarisoip.com/2007/06/29/jquerysuggest-an-alternative-jquery-based-autocomplete-library/#comment-7228
- *
- * Uses code and techniques from following libraries:
- * 1. http://www.dyve.net/jquery/?autocomplete
- * 2. http://dev.jquery.com/browser/trunk/plugins/interface/iautocompleter.js
- *
- * All the new stuff written by Peter Vulgaris (www.vulgarisoip.com)
- * Feel free to do whatever you want with this file
