+
+    BO-Logo unproblematisch für Hochschulzwecke, Institutslogo und 
+    Qualle sollte für diesen Vortrag auch unproblematisch sein, für 
+    Weitergabe unter CC-Lizenz aber Nachfrage notwendig.

+
+Here is a summary of points (a) through (c) in Section 6 of the GNU General
+Public License version 3 (GPLv3), which outlines the requirements for
+distributing object code:
+copyleft.org
+
+a) Distributing Object Code with Source Code
+You may distribute object code by providing it on a physical medium (like a CD
+or USB drive) along with the corresponding source code on a durable physical
+medium commonly used for software interchange.
+
+b) Distributing Object Code with a Written Offer
+Alternatively, you can distribute object code on a physical medium accompanied
+by a written offer, valid for at least three years (and as long as you offer
+spare parts or customer support for that product model), to provide the
+corresponding source code. This source code can be provided either on a durable
+physical medium or via access to a network server at no charge.
+docs.bmc.com
+
+--> Hier fehlt: Die "Written Offer" gilt nicht nur für den Original-Empfänger
+    des Object Code, sondern für jede*n, der*die im Besitz des Object Codes ist.
+
+c) Noncommercial Occasional Distribution
+You may occasionally and noncommercially distribute individual copies of the
+object code with a copy of the written offer to provide the corresponding
+source code, as described in point (b). This is only permitted if you received
+the object code with such an offer.
+docs.bmc.com
+
+
+
+ChatGPT 4.5:
+When distributing software covered by GPL 3.0 in object code (non-source) form,
+distributors must also provide access to the corresponding source code. They
+can fulfill this obligation in one of three ways:
+
+a) Provide source code on a physical medium alongside the object code.
+
+b) Accompany the object code with a written offer (valid at least three years
+   or as long as support/spare parts are provided) to supply the source code
+   upon request, either physically at minimal cost or via free online access.
+
+--> Dasselbe Problem wie oben.
+
+c) Occasionally and noncommercially pass along object code along with an
+   existing written offer (as described above) to provide the source code. This
+   option is limited to circumstances where the distributor originally received
+   the object code with such an offer.
