A note on per-file license headers: They're seriously ugly and incredibly bothersome to maintain.
We're doing this for fun and have better things to do than copy/pasting legal text blocks,
and staring at them each time we open one of our project files.
Seriously. We'd rather put all code in the public domain.
If you're a first-time commiter, add

Nevertheless,
Your Full Name <non-obvious aliases/nicknames, email address>

- any 3rd-party file that is added to openage **must** contain origin/licensing information at its top or to this file (else we wouldn't be allowed to use it)
- if you take any file from openage, add origin/licensing information at its top or to a file like this one (else you wouldn't be allowed to use it)
to the above list. This is not only for legal reasons, but also to keep an
overview of all those nicknames.

To get copyright/author information on specific files, use the version control system (e.g. `git blame`, or the GitHub web interface).
For some authors, the full names and/or e-mail addresses are unknown. They have
been marked by <?>. Luckily, those author's contributions are only small typo
fixes, so no copyright concerns should arise from this.
If your info is missing, wrong, or you want it to be removed for whatever
reason, please contact us.

A full list of all openage authors ("contributors") can also be determined
from the VCS, e.g. via `git shortlog -sne`, or conveniently looked up on
[the GitHub web interface](https://github.com/SFTtech/openage/graphs/contributors).

Details on individual authorships of files can be obtained via the VCS,
e.g. via `git blame`, or the GitHub web interface.

If you wish to include a file from openage in your project, make sure to
include all required legal info. The easiest way to do this would probably
be to include a copy of this file (`copying.md`), and to leave the file's
copyright header untouched.

Per-file license header guidelines:

In addition to this file, to prevent legal caveats, every source file *must*
include a header.

**openage-native** source files, that is, files that were created by
_the openage authors_, require the following one-line header, preferrably in
the first line, as a comment:

Copyright XXXX-YYYY the openage authors. See copying.md for legal info.

`XXXX` is the year when the file was created, and `YYYY` is the year when the
file was last edited. When editing a file, make sure the last-modification year
is still correct.

**3rd-party** source files, that is, files that were taken from other open-
source projects, require the following, longer header:

This file was taken from $PROJECT,
Copyright 1337-2013 Your Mom.
It's licensed under the [3-clause OpenBSD license](legal/3clausebsd).
< further legal information required by $PROJECT, such as a reference
to a copy of the $PROJECT's README or AUTHORS file >
Modifications Copyright 2014-2014 the openage authors.
See copying.md for further legal info.

The file's original license header should be additionally retained IFF
permission to remove it can't be obtained.

The "license" line is required only if the file is not licensed as
"GPLv3 or higher".

Authors of 3rd-party files should generally not be entered in the
"openage authors" list.

All 3rd-party files **must** be included in the following list:

Notes about this file:

I (mic_e) am not a lawyer. This is an open-source project, we're doing this for
fun. People convinced me that this legal shit needs doing, so I did it, even
though I'd rather have spent the time on useful parts of the project.
If you see any legal issues, feel free to contact me.
I, personally, despise in-sourcefile legal text blocks. They're a pest,
and unlike many others, I don't simply accept them because
"that is what everybody does". Thus, I worked out the minimal 1-line text above,
which should be free of legal caveats, and a reasonable compromise.
I'd be happy to see it used in other projects; you're free to use this file
(`copying.md`) as a template for your project's legal documentation.
