Rationale for the licensing choosen for LabComm
===============================================
Primary goal: the owners of systems with LabComm communication in it,
should have the liberty to replace the LabComm parts with
any software they see fit.
Secondary goal: it should be possible to release propreitary software
with LabComm.
Wanted software architecture
^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+------------------------------------------------------------+
| Propreitary software (any license) |

License considerations
^^^^^^^^^^^^^^^^^^^^^^
We need to allow linking to the LabComm library from the LGPL glue
(see http://www.gnu.org/licenses/gpl-faq.html#GPLIncompatibleLibs).
We can not set a license on generated code
(http://www.gnu.org/licenses/gpl-faq.html#GPLOutput),
but when used with the LabComm library we can force it
to be licensed under GPLv3.
Suggested license for all library files
