+# will be pulled from the host (ie. not go into the appliance now).
+#
+# The list of files that stay ('supermin.incfiles') is just a straight
+# list of files and directories.
+#
+# The list of files that come from the host ('*.supermin.hostfiles')
+# can include wildcards, to allow libraries to be upgraded on the
+# host.
