I prefer to keep my config in the code, so I added the "missing bits" to the include files. (Low Voltage programming enabled comes to mind) I hate adjusting the includes, as I'd prefer to be "compatible", but as I wanted to have control over the settings in my code, I now have to include my modified include when I share my source.
