+* 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

+    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.

 It would be a very nice thing to reduce this list to an absolute minimum, to
 reduce the footprint of busybox, especially when staticly linking with
 libraries such as uClibc.
