+config HUSH_PARSER
+       bool "Use hush shell"
+       select SYS_HUSH_PARSER
+       help
+         This option enables the "hush" shell (from Busybox) as command line
+         interpreter, thus enabling powerful command line syntax like
+         if...then...else...fi conditionals or `&&' and '||'
+         constructs ("shell scripts").
+
+         If disabled, you get the old, much simpler behaviour with a somewhat
+         smaller memory footprint.
