# This file is based on a template used by zproject, but isn't auto-generated. #
# Its primary use is to automate a number of BUILD_TYPE scenarios for the NUT #
# CI farm, but for the same reason it can also be useful to reduce typing for #
# reproducible build attempts with NUT development and refactoring workflows. #
# Note that it is driven by enviroment variables rather than CLI arguments -- #
# this approach better suits the practicalities of CI build farm technologies. #
