+// ---------------------------------------------------------
+// This is where feature definitions go. Generally speaking,
+// turning this stuff off makes things a bit smaller (and less
+// pretty/useful).
+//
+//
+//
+// 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. You can not use this and
+// USE_PROCFS at the same time... 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
+//
+// enable features that use the /proc filesystem (apps that
+// break without this will tell you on compile)...
+// You can't use this and BB_FEATURE_USE_DEVPS_PATCH
+// at the same time...
+#define BB_FEATURE_USE_PROCFS
+//
+// This compiles out everything but the most
+// trivial --help usage information (i.e. reduces binary size)
+#define BB_FEATURE_TRIVIAL_HELP
+//
+// Use termios to manipulate the screen ('more' is prettier with this on)
+#define BB_FEATURE_USE_TERMIOS
+//
+// calculate terminal & column widths (for more and ls)
+#define BB_FEATURE_AUTOWIDTH
+//
+// show username/groupnames (bypasses libc6 NSS) for ls
+#define BB_FEATURE_LS_USERNAME
+//
+// show file timestamps in ls
+#define BB_FEATURE_LS_TIMESTAMPS
+//
+// enable ls -p and -F

+//#define BB_FEATURE_INIT_CHROOT
+//
+//Make sure nothing is printed to the console on boot

+//
+//Should syslogd also provide klogd support?
+#define BB_FEATURE_KLOGD
+//
+// enable syslogd -R remotehost
+//#define BB_FEATURE_REMOTE_LOG
+//
+//Simple tail implementation (2.34k vs 3k for the full one).
+//Both provide 'tail -f' support (only one file at a time.)
+#define BB_FEATURE_SIMPLE_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_MOUNT_MTAB_SUPPORT
+//
+// Enable support for mounting remote NFS volumes.
+// You may no -o nolock if no local portmapper is running.
+#define BB_FEATURE_NFSMOUNT

+#define BB_FEATURE_MOUNT_FORCE

+// Enable support for creation of tar files.

+// Enable command line editing in the shell

+//
+//Allow the shell to invoke all the compiled in BusyBox commands as if they
+//were shell builtins. Nice for staticly linking an emergency rescue shell
+//among other thing.
+//#define BB_FEATURE_SH_STANDALONE_SHELL
+//
+//When this is enabled, busybox shell builtins can be called using full path
+//names. This causes builtins (i.e. every single busybox command) 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.
+//#define BB_FEATURE_SH_BUILTINS_ALWAYS_WIN

+// Enable tab completion in the shell (not yet
+// working very well -- so don't turn this on)

+//Turn on extra fbset options
+//#define BB_FEATURE_FBSET_FANCY
+//
+//Turn on fbset readmode support

+//#define BB_FEATURE_INSMOD_VERSION_CHECKING
+//
+// Support for Minix filesystem, version 2
+//#define BB_FEATURE_MINIX2
+//
+//
+// 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_STATUSBAR
+//
+// 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.
