**Notes**

[1] The LGPL requires us to redistribute the source code for all libraries linked
into Wing.  All of these modules are readily available on the internet.
In some cases we may have modifications that have not yet been incorporated
into the official versions; if you wish to obtain a copy of our version
of the sources of any of these modules, please email us at `info at wingware.com`__.

__ mailto:info@wingware.com

[2] Docutils contains a few parts under other licenses (BSD, Python 2.1,
Python 2.2, Python 2.3, and GPL). See the COPYING.txt file in the source
distribution for details.

[3] The Python Software Foundation License version 2 is an OSI Approved Open 
Source license.  It consists of a stack of licenses that also include other
licenses that apply to older parts of the Python code base.  All of these
are included in the OSI Approved license: PSF License, BeOpen Python License,
CNRI Python License, and CWI Python License.  The intellectual property 
rights for Python are managed by the `Python Software Foundation
<https://python.org/psf>`__.

[4] Not OSI Approved, but similar to other OSI approved licenses. The license grants
anyone to use the software for any purpose, including commercial applications.

[5] The source code states the author has disclaimed copyright of the source
code. The sqllite.org website states: "All of the deliverable code in SQLite
has been dedicated to the public domain by the authors. All code authors, and
representatives of the companies they work for, have signed affidavits
dedicating their contributions to the public domain and originals of those
signed affidavits are stored in a firesafe at the main offices of Hwaci.
Anyone is free to copy, modify, publish, use, compile, sell, or distribute the
original SQLite code, either in source code form or as a compiled binary, for
any purpose, commercial or non-commercial, and by any means."

[6] Qt is available under several licenses.  The LGPL v. 2.1 version of the
software was used for Wing.
