Xeolabs SceneJS

It's very difficult to figure out what license SceneJS is distributed under. When you download SceneJS, there's no license file, and there's no copyright block at the top of scenejs.js. Doing a recursive case-insensitive search for "license" through the unpacked download reveals that both identical copies (!) of the Seymour plane are licensed under the SCEA Shared Source license, and that some section of scenejs.js is licensed under "a BSD-style license that can be found in the LICENSE file". (There's no way to tell how much of scenejs.js is under that license, and the LICENSE file is not shipped as part of the download.)

Then I looked at the web site. The front page has a "licenses" link that leads to your git repository, which lists the GPL and MIT licenses. OK; in my experience, if a project's source tree has multiple license files, that usually means that some files are licensed under one license and some under the other, with markings (copyright notices in the files, README files in directories, etc.) that explain which code is under which license.

So, let's try again with the recursive case-insensitive search for "license", this time in the git repository instead of the download. OK, there seem to be some components in lib/ that have proper license information. The case of remote.concise.js seems a little strange -- distributed under a Creative Commons Attribution license, but has no attribution. But remote seems to be entirely unused, so that's probably not a big problem -- it can just be removed. The root directory build.xml says that "sourcefiles" is supposed to include a file "license.txt". There is no file "license.txt". The two identical copies (!) of the Seymour plane are still licensed under the SCEA Shared Source license. webgl-trace.js is licensed under "a BSD-style license that can be found in the LICENSE file" -- OK, now I can reliably figure out how much of scenejs.js is under that license, but the LICENSE file is still missing.

And that's it.

And then I resort to randomly clicking on the web site, and I do eventually find the FAQ entry that says "Is SceneJS Free?
You bet - under both the GPL and MIT licenses . Choose whichever of these fits your needs best." Excellent news! This makes me happy. But I'm sure it took me more than 10 minutes to find this information, and it was only by chance that I found it at all. It shouldn't be this hard. Even then, it's not totally clear. What do you mean by "SceneJS" being under the GPL and MIT licenses? Certainly not the entire SceneJS download, that has those two identical copies (!) of the Seymour plane; and not the git repository, that also has remote.concise.js, rhino, etc. I'm going to assume that you mean that the src/scenejs directory in the git repository, and the lib/scenejs.js file in the download, are dual-licensed GPL/MIT (except for webgl-trace.js, which is distributed under some BSD-style license with a missing LICENSE file), which is good enough for me.
