+# We accept -n, -e, -f, and -i with no backup extension. We support
+# extended regular expressions using the -r argument. Note that extended
+# regular expressions support may not be retained, depending upon the
+# capabilities of the other platforms we wish to support, and we may need
+# to reimplement -i internally in this script on some platforms.
