+   3	'x' if the owner may execute, 's' if the file is
+	set-user-id, '-' otherwise.
+	'S' if the file is set-user-id, but the execute
+	bit isn't set.

+	set-group-id, '-' otherwise.
+	'S' if it is set-group-id but not executable.

+   7	'r' if any user may read, '-' otherwise.
+
+   8	'w' if any user may write, '-' otherwise.
+
+   9	'x' if any user may execute, 't' if the file is "sticky"
+	(will be retained in swap space after execution), '-'
+	otherwise.
+	'T' if the file is sticky but not executable. */
