// ---------------------------------------------------------
// 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.

#define BB_FEATURE_EXTRA_QUIET
//
// enable syslogd -R remotehost
#define BB_FEATURE_REMOTE_LOG
//
// enable syslogd -C
//#define BB_FEATURE_IPC_SYSLOG
//
//Disable for a simple tail implementation (2.34k vs 3k for the full one).
//Both provide 'tail -f', but this cuts out -c, -q, -s, and -v. 
#define BB_FEATURE_FANCY_TAIL
//
// Enable support for loop devices in mount
#define BB_FEATURE_MOUNT_LOOP
//
// Enable support for a real /etc/mtab file instead of /proc/mounts
//#define BB_FEATURE_MTAB_SUPPORT
//
// 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
// uClibc with INCLUDE_RPC=true (contained in the Config file)
#define BB_FEATURE_NFSMOUNT
//
// Enable support forced filesystem unmounting 
// (i.e., in case of an unreachable NFS system).
#define BB_FEATURE_MOUNT_FORCE
//
// Enable support for creation of tar files.
#define BB_FEATURE_TAR_CREATE
//
// Enable support for "--exclude" and "-X" for excluding files

//
// Enable reverse sort

// Enable command line editing in the shell.  
// Only relevant if a shell is enabled. On by default.

//
// 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 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.
//#define BB_FEATURE_ASH_JOB_CONTROL
//
//Turn on extra fbset options
#define BB_FEATURE_FBSET_FANCY

//#define BB_FEATURE_OLD_MODULE_INTERFACE
//
// Support module version checking
#define BB_FEATURE_INSMOD_VERSION_CHECKING
//
// Support for uClinux memory usage optimization, which will load the image
// directly into the kernel memory.  This divides memory requrements by three.
// If you are not running uClinux (i.e., your CPU has an MMU) leave this
// disabled...
//#define BB_FEATURE_INSMOD_LOADINKMEM
//
// Support for Minix filesystem, version 2
#define BB_FEATURE_MINIX2
//
// Enable ifconfig status reporting output -- this feature adds 7k.
#define BB_FEATURE_IFCONFIG_STATUS

//
// Enable ifconfig options "mem_start", "io_addr", and "irq".

//
// Enable ifconfig option "hw".  Currently works for only with "ether".
#define BB_FEATURE_IFCONFIG_HW
//
// Allows "broadcast +" to set broadcast automatically based on hostaddr
// and netmask, at a cost of about 100 bytes of code (i386).
#define BB_FEATURE_IFCONFIG_BROADCAST_PLUS
//
// Enable busybox --install [-s]
// to create links (or symlinks) for all the commands that are 
// compiled into the binary.  (needs /proc filesystem)
//#define BB_FEATURE_INSTALLER
//
// Enable a nifty progress meter in wget (adds just under 2k)
#define BB_FEATURE_WGET_STATUSBAR
//
// Enable HTTP authentication in wget
#define BB_FEATURE_WGET_AUTHENTICATION
//
// Clean up all memory before exiting -- usually not needed
// as the OS can clean up...  Don't enable this unless you
// have a really good reason for cleaning things up manually.
//#define BB_FEATURE_CLEAN_UP
//
// Support for human readable output by ls, du, etc.(example 13k, 23M, 235G)
