It limits you, among other limitations, to distribute free software program as combined with proprietary program. It limits you, among other limitations, to make a combined program with a free software program, unless the free software program is licensed under the LGPL.

The license of a GPL program does not allow making a combined program with it and not license it under same terms. I am asking you to make your homework first, as it is not good spreading misleading information on the mailing list that remains in the public forever. Read: https://en.wikipedia.org/wiki/GNU_Lesser_General_Public_License Quote: The GNU Lesser General Public License (LGPL) is a free-software license published by the Free Software Foundation (FSF). The license allows developers and companies to use and integrate a software component released under the LGPL into their own (even proprietary) software without being required by the terms of a strong copyleft license to release the source code of their own components. However, any developer who modifies an LGPL-covered component is required to make their modified version available under the same LGPL license. For proprietary software, code under the LGPL is usually used in the form of a shared library, so that there is a clear separation between the proprietary and LGPL components. The LGPL is primarily used for software libraries, although it is also used by some stand-alone applications. Read: https://en.wikipedia.org/wiki/GNU_Lesser_General_Public_License#Differences_from_the_GPL Emacs is not LGPL, and license does not allow combining code with proprietary programs. So, no, you cannot require 'seq or any other Emacs library in a proprietary program without violation of the GPL. -- Jean Take action in Free Software Foundation campaigns: https://www.fsf.org/campaigns Sign an open letter in support of Richard M.
