-	  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.
