Now that "make sizes" is in, the faq should mention it...

-       To examine a busybox binary with an eye to saving bytes, build an
-       optimized debug version and run the "nm" command against it, like so:

-       make clean && make STRIPCMD=/bin/true && nm --size-sort busybox

-       This gives a list of symbols and the amount of space allocated for
-       each one, sorted by size.  (Note: do not enable CONFIG_DEBUG for this,
-       as that disables compiler optimization which is great for running gdb
-       but misleading when trying to figure out how much space each component
-       is really using under normal circumstances.)
+       The busybox Makefile can generate a report of how much space is actually
+       being used by each function and variable.  Run "<b>make sizes</b>" (preferably
+       with CONFIG_DEBUG off) to get a list of symbols and the amount of
+       space allocated for each one, sorted by size.
