The PLM software was written internally by the team. This software is

The pedagogical material distributed with the PLM is covered both by
the GPLv3 license (mainly for the included code) and by the CC-BY-SA
license (mainly for the other media files). But the exact boundary
here between the source code and the media is left as an exercise to
the reader, so this material is distributed under both licenses for
sake of simplicity.
The GPLv3 license can be found in the archive under the name
LICENSE-GPL-3. The CC-BY-SA license can be found online:

The whole artwork is free content, licenced under CC-BY-SA, GPL, LGPL

borowed from free collections. The specific license and origin of each
files is listed below.

img/btn-reset.png is a mashup of mine between btn-start.png (CC-BY-SA) and
http://openiconlibrary.sourceforge.net/gallery2/?./Icons/actions/run-rebuild.png
(LGPL-2.1). The result can be used under either licence.
Several exercises provide screenshot of PLM itself to help the
student. These images are naturally CC-BY-SA too.

We borrowed the following icons, that are CC-BY-SA too:
* The bunny and egg in BuggleQuest universe come from:

The following images come from the LibreOffice icon set. They are thus

The following logos are GPLv2:
img/busyicon/*: (gnome) http://openiconlibrary.sourceforge.net/gallery2/?./Icons/animations/process-working.png
img/world_turtle.png : stolen to the kturtle project, that is GPLv2+
=========================================================================
The logos of the programming languages are certainly free, even if I
didn't dig for their exact licence.

Public domain images (CC0 PD)
* img/focus_* These images were retrieved from http://openclipart.org/
even if I didn't write down the exact URL for them.
* img/trophy.png http://openclipart.org/detail/48937/trophy-by-sheikh_tuhin
* img/world_baseball.png http://openclipart.org/detail/76927/baseball2-by-shokunin
=========================================================================
The following images are believed to be free, even if I cannot
remember where they come from. We should maybe play safe and replace
them. But as you can see from the rest of the project, we are
better programmers than designers... You are welcome if you can help.
* src/lessons/sort/pancake/img/world_pancake.png
It was retrieved from
http://omgwtflols.deviantart.com/art/Pixel-Art-Pancakes-with-syrup-298700868
It seems rather free, but the exact license is not known.
* img/world_lesson.png
I cannot remember where it comes from. It looks very similar to the
logo for education applications in KDE so I guess it's ok. And since
I'm planning at removing the whole concept of lessons, it's probably
not worth digging any further on this one.
