Extjs are they legally using YUI code?   Topic List   < Prev Topic  |  Next Topic >

Re: [ydn-javascript] Re: Extjs are they legally using YUI code?

flexidx503,

The BSD license permits liberal reuse, including reuse in commercial software.

Redistributing YUI code in any form without including the license text is not permitted under the terms of the license.


Regardless of the terms under which ExtJS license its product, you will always be able to download YUI and use it under the terms of the BSD license.

Regards,
Eric

they sell a commercial license to code that Yahoo wrote and licensed
