-// This file defines the feature set to be compiled into busybox.
-// When you turn things off here, they won't be compiled in at all.
-//
-//// This file is parsed by sed. You MUST use single line comments.
-// i.e. //#define BB_BLAH
-//
-//
-// BusyBox Applications
-#define BB_INSMOD
-// End of Applications List
-//
-//
-//
-// ---------------------------------------------------------
-// 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
-
-//
-// Enable tab completion in the shell (not yet
-// working very well -- so don't turn this on)
-//#define BB_FEATURE_SH_TAB_COMPLETION
-//
-//Turn on extra fbset options
-//#define BB_FEATURE_FBSET_FANCY
-//
-//Turn on fbset readmode support
-//#define BB_FEATURE_FBSET_READMODE
-//
-// You must enable one or both of these features
-// Support installing modules from pre 2.1 kernels
-//#define BB_FEATURE_INSMOD_OLD_KERNEL
-// Support installing modules from kernel versions after 2.1.18
-#define BB_FEATURE_INSMOD_NEW_KERNEL
-//
-// Support module version checking
-//#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
-//
-// 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
-//
-// End of Features List
-//
-//
-//
-//

-//---------------------------------------------------
-// Nothing beyond this point should ever be touched by
-// mere mortals so leave this stuff alone.
