hush is a very small shell (just 18k) and it has fairly complete
Bourne shell grammar. It even handles all the normal flow control

- lash is the very smallest shell (adds just 10k) and it is quite
- usable as a command prompt, but it is not suitable for any but the
- most trivial scripting (such as an initrd that calls insmod a few
- times) since it does not understand any Bourne shell grammar. It
- does handle pipes, redirects, and job control though. Adding in
- command editing makes it a very nice lightweight command prompt.
-
+ lash is deprecated and will be removed, please migrate to hush.

+ This option causes busybox shells [currently only ash]
+ to not execute typical fork/exec/wait sequence, but call <applet>_main
+ directly, if possible. (Sometimes it is not possible: for example,
+ this is not possible in pipes).
+
+ This will be done only for some applets (those which are marked
+ NOFORK in include/applets.h).

+ This may significantly speed up some shell scripts.
