-	  Please submit a patch to add help text for this item.
+	  There are 3 ways BusyBox can handle buffer allocations:
+	  - Use malloc. This costs code size for the call to xmalloc.
+	  - Put them on stack. For some very small machines with limited stack
+	    space, this can be deadly.  For most folks, this works just fine.
+	  - Put them in 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

+	  Enable if you want BusyBox to use Unix98 PTY support. If enabled,
+	  busybox will use /dev/ptmx for the master side of the pseudoterminal
+	  and /dev/pts/<number> for the slave side.  Otherwise, BSD style
+	  /dev/ttyp<number> will be used. To use this option, you should have
+	  devpts or devfs mounted.

-	  Please submit a patch to add help text for this item.
+	As a size optimization, busybox by default does not cleanup memory
+	that is dynamically allocated or close files before exiting. This
+	saves space and is usually not needed since the OS will clean up for
+	us.  Don't enable this unless you have a really good reason to clean
+	things up manually.
