// ---------------------------------------------------------
// This is where feature definitions go.  Generally speaking,
// turning this stuff off makes things a bit smaller (and less 
// pretty/useful).
//
//
// If you enabled BB_SH above, you may select one of the following shells.  
// You can only select ONE of the following shells.  Sorry.
//
// 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
// will be restored for the next BusyBox release.
//#define BB_FEATURE_ASH
//
// 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.
//#define BB_FEATURE_USE_DEVPS_PATCH
//
// show verbose usage messages
//#define BB_FEATURE_VERBOSE_USAGE
//
// Use termios to manipulate the screen ('more' is prettier with this on)
//#define BB_FEATURE_USE_TERMIOS

//
// enable syslogd -C
//#define BB_FEATURE_IPC_SYSLOG
//
//Disable for a simple tail implementation (2.34k vs 3k for the full one).

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

// not running a local portmapper daemon...
//#define BB_FEATURE_NFSMOUNT

// (i.e., in case of an unreachable NFS system).

//
// Attempts to match usernames in a ~-prefixed path
//#define BB_FEATURE_COMMAND_USERNAME_COMPLETION
//
//Allow the shell to invoke all the compiled in BusyBox applets as if they
//were shell builtins.  Nice for staticly linking an emergency rescue shell,
//among other things. Off by default.
// Only relevant if BB_SH 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 BB_SH 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 BB_SH is enabled.

// If you are not running uClinux (i.e., your CPU has an MMU) leave this
// disabled...
