+<h2><a name="optimize">I want to make busybox even smaller, how do I go about it?</a></h2>
+<p>
+ To conserve bytes it's good to know where they're being used, and the
+ size of the final executable isn't always a reliable indicator of
+ the size of the components (since various structures are rounded up,
+ so a small change may not even be visible by itself, but many small
+ savings add up).
+</p>
+<p>
+ 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:
+</p>
+<p>
+ make clean && make STRIPCMD=/bin/true && nm --size-sort busybox
+</p>
+<p>
+ 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.)
+</p>
