                   SMILE LICENSE INFORMATION

    Copyright (c) 2010-2021 Haifeng Li. All rights reserved.

  SMILE employs a dual license model designed to meet the development
  and distribution needs of both commercial distributors (such as OEMs,
  ISVs and VARs) and open source projects.


GNU General Public License Usage

  SMILE may be used under the terms of the GNU General Public License
  version 3 as published by the Free Software Foundation and appearing
  in the file COPYING included in the Software. In order to preserve
  the true meaning of open development and uphold the spirit of free
  software, it is imperative that the rules and regulations of open
  source licenses required by the Free Software Foundation are followed.

  The SMILE open source licensing is ideal for use cases such as
  Free Open Source Software ("FOSS") applications under the GPL
  that want to combine and distribute those FOSS applications with
  SMILE software, student/academic purposes, hobby projects,
  internal research projects without external distribution,
  or other projects where all GPL obligations can be met.



Commercial License Usage

  OEMs (Original Equipment Manufacturers), ISVs (Independent Software
  Vendors), VARs (Value Added Resellers) and other distributors that
  combine and distribute commercially licensed software with SMILE
  must enter into a commercial license agreement with SMILE.AI, LLC.

  The commercial SMILE license gives you the full rights to create
  and distribute software on your own terms without any open source
  license obligations. With the commercial license you also have
  access to the official SMILE Support and close strategic relationship
  with SMILE.AI, LLC to make sure your development goals are met.
