// ---------------------------------------------------------
// This is where feature definitions go.  Generally speaking,
// turning this stuff off makes things a bit smaller (and less 
// pretty/useful).
//
//
// If you enabled one or more of the shells, you may select which one
// should be run when sh is invoked:
//#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
// I emailed Linus and this patch will not be going into the stock kernel.

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

//
// Enable support for mounting remote NFS volumes. 
// You may need to mount with "-o nolock" if you are
// not running a local portmapper daemon...
//
// If you are using uClibc, be sure that you've already compiled

//#define BB_FEATURE_NFSMOUNT

// 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

//
// Allows "broadcast +" to set broadcast automatically based on hostaddr
