BSD style License

I am developing a CMS site I have written the entire back end myself, but do not really wish to get into writting a Javascript WYSIWYG editor I am looking at using one of the many avaliable on the web. The one I like is released under a BSD style license. Even after reading the license I am not totally sure, but can I incorporate the widget into my system and still legaly sell my system? TIA
