- 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
-</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.)
+ 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.
