Notes

[1] The LGPL requires us to redistribute the source code for all libraries linked into Wing IDE. 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.

[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.

[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 IDE.
