MIT and (L)GPL license compliance junk

[dodexahedron]

First of all, THANK YOU FOR THIS TOOL! Now that wimwitch is defunct, this is definitely the best I've been able to find that is open source. Many kudos to everyone.

But just wanted to point out that, because the 7zip library is being distributed in binary form, compliance with the LGPL requires more than just including the license text file.

Most importantly is providing information on how to acquire the source that was used for the distributed binary.

LGPL is an extension of and partial exemption to the corresponding GPL version. LGPL 3 specifically exempts only section 3 of the GPL version 3, on condition of complying with all terms of section 4 of the LGPL. The rest of the regular GPL still applies, however.

The short and sweet version is that distributing 7-zip in binary form requires either providing the source used to build it and instructions for building it OR (much more preferably, I'm sure) providing a link to where it was acquired from that complies with the same, as laid out in section 6, paragraph d of the GPL.

So I think linking to wherever you got it from would be sufficient. All the better if it was directly from 7-zip.org. If it was, here's the link to their downloads page for your convenience: https://7-zip.org/download.html

But it has to accompany the releases, specifically - not just the link to 7-zip.org that is in the README.md in the repo.

Looks like a couple other minor additions to releases might be needed, too.

Looks like the LICENSE file, which is in the zip release, (👍) only contains specifically the GNU GPL Version 3

The LGPL 3.0 and the MIT license text both also need to be there, for .net and for 7zip unless they're "displayed prominently" in the application. May as well just append them to the LICENSE file, mentioning what general components they're applicable to.

And of course the repo links to go with them for source code.

Here's the dotnet github org link or the runtime repo, specifically.

Hi @dodexahedron. First, you're welcome. I'm glad you found this useful.

Secondly, DT already contains the license for 7-Zip. Both it and the license were grabbed from the official site.

As per the license, you'll have to look at the About screen. Go to the LICENSES section and you'll find a section for 7-Zip.
