+// 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 Bourne shell grammer. It does handle pipes, redirects, and
+// job control though. Adding in command editing makes it very nice
+// lightweight command prompt.
+//#define BB_FEATURE_LASH
+//
+// hush is also quite small (just 18k) and it has very complete Bourne shell
+// grammer. It handles if/then/else/fi just fine, but doesn't handle loops
+// like for/do/done or case/esac and such. It also currently has a problem
+// with job control.
+//#define BB_FEATURE_HUSH
+//
+// msh: 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 grammer (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. This was only recently added, so there is still
+// room to shrink it further...
+#define BB_FEATURE_MSH
+//
+// ash: This adds about 60k in the default configuration and is the most
+// complete and most pedantically correct shell included with busybox. This
+// shell was also recently added, and several people (mainly Vladimir and Erik)
+// have been working on it. There are a number of configurable things at the
+// top of ash.c as well, so check those out if you want to tweak things. The
+// Posix math support is currently disabled (that bit of code was horrible) but

// BusyBox will, by default, malloc space for its buffers. This costs code

// space, this can be deadly. For most folks, this works just fine...
//#define BB_FEATURE_BUFFERS_GO_ON_STACK
+// The third alternative for buffer allocation is to use BSS. This works
