+# It relies on a known format of the .yml.sample files which haven't
+# been made easier to parse to still let humans copy them manually and
+# do further editing or leave them as such to get the same setup as before
+# the introduction of this script.

+# by invoking with the --help switch. More switches will be added
+# as the need/request for them arises.
