-# This script is intended to be called by automation or humans,
-# from a specially configured environment.  Depending on the contents
-# of various variable, entirely different operations will be performed.
+# This script runs in the Cirrus CI environment, invoked from .cirrus.yml .
+# It can also be invoked manually in a `hack/get_ci_cm.sh` environment,
+# documentation of said usage is TBI.
+#
+# The principal deciding factor is the $TEST_FLAVOR envariable: for any
+# given value 'xyz' there must be a function '_run_xyz' to handle that
+# test. Several other envariables are used to differentiate further,
+# most notably:
+#
+#    PODBIN_NAME  : "podman" (i.e. local) or "remote"
+#    TEST_ENVIRON : 'host' or 'container'; desired environment in which to run
+#    CONTAINER    : 1 if *currently* running inside a container, 0 if host
