Icon Experience Collection
Selected 16x16 icons within the isomorphic/skins directory are part of the Icon Experience collection 
(http://www.iconexperience.ru) and may be freely used with any SmartClient components without charge, 
but may not be used as part of screen designs separate from SmartClient components without a purchase 
of a license from Icon Experience. We are working to replace these icons as soon as possible.
All other media found under the isomorphic/skins directory may be used under the LGPLv3.
Commercial Licenses
A number of commercial licenses are available for purchase. Please see http://smartclient.ru/license.
