+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.
+
+

+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.
