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.

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.

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.
