-	  Since sprintf() can overflow its buffer, it is common to use
-	  snprintf() instead, which knows the buffer size and can avoid
-	  overflow. However, this does increase code size slightly (for

-	  using sprintf() with data you do not control.
+	  This option enables a tiny, stripped down printf version.
+	  This should only be used in space limited environments,
+	  like SPL versions with hard memory limits. This version
+	  reduces the code size by about 2.5KiB on armv7.
