These days a lot of people contribute new layouts/variants/models to xkeyboard-config. Usually it is done through the freedesktop.org's bugzilla. Quite often that contributed code requires manual "polishing" which would be unnecessary if authors would follow some simple rules. Till today, they really could not be blamed - because these rules existed only in my head. Now, these rules are published. So do not tell me you were not warned ;)
PS I still highly appreciate every contribution to the project. I just would like to make my life a bit easier. Thanks for understanding.
