The PDF files named tuc_*, tuckhs_*, and tuckhseng_* are deliberately
fictional placeholder marks generated by tools/generate-placeholder-logos.py
in the development repository. They are not official TU Chemnitz logos and
do not claim affiliation or endorsement.
They may be distributed under the same license as osglecture.

The osg*.png files are separate OSG project artwork and are not generated by
that script.
