+# Test script that creates an netns and connect it with
+# veth pairs. On the other end, it runs pppoe-server.
+# It also creates a NetworkManager profile that can be activated.
+#
+# Usage:
+#
+# ./test-ppp.sh [setup]: create the setup. This implies a "cleanup"
+#   first.
+# ./test-ppp.sh cleanup: cleanup the things that the script created.
