ExtJS license

[Nils Philippsen]

Hi all,

I'm thinking about wrapping up ExtJS (a JavaScript framework,
http://extjs.com) for TurboGears and wondered if the license conditions
are okay for it to be included in Fedora. Note that there are two stable
versions, v1.1 and v2.0, which are partly incompatible and there is code
that won't work with the newer one.

Basically it sounds to me like "LGPLv3 for the JavaScript code, other
assets (graphics, style sheets) may only be shipped with these
components" which seems to be what we allow for e.g. games where artwork
often has a restrictive license, but anyway here are the relevant bits
from LICENSE.txt in the relevant ZIP archive:

--- 8< --- ExtJS v1.1.1 -------
http://extjs.com/license

The CSS and Graphics ("Assets") distributed with Ext are licensed for
use ONLY with their associated Ext JavaScript component ("Component").
Use of the Assets in any way that does not also include the Component is
prohibited without explicit permission from Ext JS, LLC.  Deriving
images and CSS from the Assets in an effort to bypass this license is
also prohibited.
