Merge lp:~widelands-dev/widelands/copyright-file into lp:~widelands-dev/widelands/debian

[Hans Joachim Desserud]

Update the copyright file in debian packaging to document the various licenses origins of files used. Mainly to incorporate the new fonts we now bundle, but I also thought we should probably mention our third party libraries.

We have not yet documented all of these properly though, see copyright.todo for details on remaining work. There are some questions there where I'm not sure how to proceed. I'm also open for other feedback.

I think it is possible to add individual people as reviewers, so I'll add GunChleoc (since you added the fonts) and Martin Quinson since you're the Debian maintainer and probably know more about this than me. Being appointed as reviewers will presumably ping you so that you are aware of this merge proposal. Combined I believe we can answer the questions I have posted, and get the copyright file up to date. :)

I used diff comments to add some more info.

This is surprisingly hard.

I did have some progress when I discovered that I can open fonts in FontViewer on Ubuntu and it will be able to disply embedded information such as copyright information.

ping. hjd, what is the state of this branch?

>ping. hjd, what is the state of this branch?

Hello hello. Not much has happened since the previous commit/comment.

Like I talked about in https://code.launchpad.net/~hjd/widelands/tests-poc/+merge/250533, the main intent with this branch was to get the packaging in a better shape to make it easier to create the official Debian packages once we release build19 (rc). It is my understanding that the Debian policies require packages to give full copyright statement on their content, so since it will need to be done anyways we might as well get it done early.

This work is not critical for Widelands itself since we don't really have such obligations (unless specific licenses state otherwise) but is in general nice to give credit to other people's work which we include. I'd say we are doing a good job of this though, at least with the fonts/licenses there.

As I mentioned, I believe this work will need to be done for the offical Debian packages, which is why I wanted to start it straight away, while the new fonts were still fresh. This is also why I added the Debian maintainer as a reviewer here, hoping to get some feedback and possibly guidance.

I am a bit stuck on the questions in the todo, and I don't really know how to proceed with this. I'll leave this open for a while longer, but if I don't hear anything, I'll likely close it as a draft/experiment. While I would like to see this done properly, I don't know whether the current state of the branch does more good than harm, and I don't think it is that critical for the Widelands project to have this file 100% completed.

I'm so deep under water wrt my daytime job that I am completely unable to help (or even properly read your emails) before the summer.

Sorry and good luck

No problem Martin, that's completely understandable. Thanks for letting us know. :)

In the meantime, I'll just put this branch on ice, and we'll get back to it when we have a better idea on how to proceed. I'll try to adjust the review status so that it doesn't show up in the list of active reviews.
