it should be possible to update ncf
As a user of ncf I'm supposed to write my own promisses in subfolders of ncf (50_techniques and 60_services) or even edit a file that comes with ncf (service_mapping.cf). After I've done this, it's not easy to update ncf.
It would be preferable to have all of ncf in one subfolder that I don't need to touch at all as a user. Than on updates I can delete the folder and copy the new ncf version in its place.
If you have another better solution please add it to the documentation!
