# Unlike the MASH role repositories, where one repository holds one role, every
# role here lives in the same repository. Running every scenario on every push
# would be unaffordable, so a first job works out which roles the push actually
# touched and the matrix is built from that. A push that changes documentation,
# or a role with no scenario yet, runs nothing at all.
