Is it?  I didn't realize that and I still don't :(

Alright.  My bad.  I'll go back and read the ML...

So, I went back and re-read the "Make busybox an applet" threads where
"turn off help and list of applets" is mentioned.

And my understandig now is that if CONFIG_BUSYBOX=y, the '--help',
'--list' and '--list-full' options are removed, and at the same time
adds about 900 bytes to the binary.

I may be thick, but what I still don't understand is what benefits
does that bring?
