netkit-tiny. Per discussions on the mailing list, this isn't going
to happen. False alarm. Sorry about the confusion.
-* The busybox shell, lash, is really too weak for serious use, although it is

- that will result in a new shell that understands the full Bourne grammar.
- This new shell is being championed by Larry Doolittle

+* The default busybox shell, lash, is really too weak for serious use,

+ 0.52 now contains a rewritten shell, hush, which understands most
+ Bourne grammar, with only about a 4 Kbyte binary size penalty. You can
+ engage hush at pre-compile time by "ln -sf hush.c sh.c; touch hush.c".
+ Hush is young, and has plenty of bugs to shake out, so think twice before
+ using it for production systems. We welcome bug reports and patches.
