-         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
-         Thumb-2, about 420 bytes). Enable this option for safety when
-         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.

+         The supported format specifiers are %c, %s, %u/%d and %x.
