## Usage of flavour function
#
# flavour <flavour-name> <part-1> <part-2> ...
# - <flavour-name> is used for the filename: docker-compose.<flavour-name>.yml
# - <part-1> and <part-2> ... shoud be files like docker-compose-parts/<part-1>.yml
# - variants build and devel sould be like docker-compose-parts/<part-1>.build.yml
# and docker-compose-parts/<part-1>.devel.yml
