# Building packages
#
# The following rules build osbuild packages from the current HEAD commit,
# based on the spec file in this directory. The resulting packages have the
# commit hash in their version, so that they don't get overwritten when calling
# `make rpm` again after switching to another branch.
#
# All resulting files (spec files, source rpms, rpms) are written into
# ./rpmbuild, using rpmbuild's usual directory structure.
