Makefile

#
# Maintenance Scripts
#
# This Makefile contains a random selection of targets for easy development.
# They mostly serve as example how most of the build/test infrastructure is
# used. Feel free to adjust them to your needs.
#

#
# The gcc warning-sets -Wall and -Wextra enable some annoying warnings, which
# we really do not care about. Disable them here. Additionally, add some
# warnings that we consider mandatory for our code-base.
