#define BB_FEATURE_SH_IS_ASH
//#define BB_FEATURE_SH_IS_HUSH
//#define BB_FEATURE_SH_IS_LASH
//#define BB_FEATURE_SH_IS_MSH
//
// BusyBox will, by default, malloc space for its buffers. This costs code
// size for the call to xmalloc. You can use the following feature to have
// them put on the stack. For some very small machines with limited stack
// 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
// beautifully for computers with a real MMU (and OS support), but wastes
// runtime RAM for uCLinux. This behavior was the only one available for
// BusyBox versions 0.48 and earlier.
//#define BB_FEATURE_BUFFERS_GO_IN_BSS
//
// Turn this on to use Erik's very cool devps, and devmtab kernel drivers,
// thereby eliminating the need for the /proc filesystem and thereby saving
// lots and lots memory for more important things. NOTE: If you enable this
// feature, you _must_ have patched the kernel to include the devps patch that
// is included in the busybox/kernel-patches directory. You will also need to
// create some device special files in /dev on your embedded system:
// mknod /dev/mtab c 10 22
// mknod /dev/ps c 10 21

//
// Enable support for a real /etc/mtab file instead of /proc/mounts

// Only relevant if a shell is enabled.
//#define BB_FEATURE_SH_STANDALONE_SHELL
//
//When this is enabled, busybox shell applets can be called using full path
//names. This causes applets (i.e., most busybox commands) to override
//real commands on the filesystem. For example, if you run run /bin/cat, it
//will use BusyBox cat even if /bin/cat exists on the filesystem and is _not_
//busybox. Some systems want this, others do not. Choose wisely. :-) This
//only has meaning when BB_FEATURE_SH_STANDALONE_SHELL is enabled.
// Only relevant if a shell is enabled. Off by default.
//#define BB_FEATURE_SH_APPLETS_ALWAYS_WIN
//
// Uncomment this option for a fancy shell prompt that includes the
// current username and hostname. On systems that don't have usernames
// or hostnames, this can look hideous.
// Only relevant if a shell is enabled.
//#define BB_FEATURE_SH_FANCY_PROMPT
//
// Uncomment this option to disable job control. Job control lets you
// run jobs in the background (which completely useless for is all you
// are doing is running scripts). Disabing this is bad for interactive
// use, since when you hit ^C in an application, it will also kill the
// shell. This adds about 2.5k on an x86 system.

// Enable HTTP authentication in wget
