Hey,
yes, the header seems a good solution for this
Also not sure that what I did is backwards compatible but you’ll have to review it anyway before you pull it…
It is not important for now, also when using the header and there is no we can just use 1201
Took me 3 hours to set everything up, not sure it was really worth it…
That is ugly, we need to improve this. What exactly took you so long? Maybe you should have choosen the IDE way e.g. via NetBeans, where you normally only need to open the project, instead of the command line fiddling?
Also it is really important that you do not see this as waste of time, I hope, as many changes are only possible via a good and vibrant community 
So I really appreciate any inputs and improvements on all sides!
I have change the code and ran the tests to make sure I didn’t broke any thing.
Yes, in case your changes break things, do not worry, then our tests coverage is broken and needs to be fixed!
