+ Tha 'ash' shell adds about 60k in the default configuration and is
+ the most complete and most pedantically correct shell included with
+ busybox. This shell is actually a derivative of the Debian 'dash'
+ shell (by Herbert Xu), which was created by porting the 'ash' shell
+ (written by Kenneth Almquist) from NetBSD.

+config BUSYBOX_CONFIG_HUSH
+ bool "hush"
+ default n
+ help
+ hush is a very small shell (just 18k) and it has fairly complete
+ Bourne shell grammar. It even handles all the normal flow control
+ options such as if/then/elif/else/fi, for/in/do/done, while loops,
+ etc.
+
+ It does not handle case/esac, select, function, here documents ( <<
+ word ), arithmetic expansion, aliases, brace expansion, tilde
+ expansion, &> and >& redirection of stdout+stderr, etc.
+
+
+config BUSYBOX_CONFIG_LASH
+ bool "lash"
+ default n
+ help
+ 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.
+
+
+config BUSYBOX_CONFIG_MSH
+ bool "msh"
+ default n
+ help
+ The minix shell (adds just 30k) is quite complete and handles things
+ like for/do/done, case/esac and all the things you expect a Bourne
+ shell to do. It is not always pedantically correct about Bourne
+ shell grammar (try running the shell testscript "tests/sh.testcases"
+ on it and compare vs bash) but for most things it works quite well.
+ It also uses only vfork, so it can be used on uClinux systems.

+ help
+ This option causes the selected busybox shell to use busybox applets
+ in preference to executables in the PATH whenever possible. For
+ example, entering the command 'ifconfig' into the shell would cause
+ busybox to use the ifconfig busybox applet. Specifying the fully
+ qualified executable name, such as '/sbin/ifconfig' will still
+ execute the /sbin/ifconfig executable on the filesystem. This option
+ is generally used when creating a staticly linked version of busybox
+ for use as a rescue shell, in the event that you screw up your system.
+
+ Note that when using this option, the shell will attempt to directly
+ run '/bin/busybox'. If you do not have the busybox binary sitting in
+ that exact location with that exact name, this option will not work at
+ all.
