+          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
+            earlier.

+          All BusyBox applets will show more verbose help messages when
+          busybox is invoked with --help.  This will add lots of text to the
+          busybox binary.  In the default configuration, this will add about
+          13k, but it can add much more depending on your configuration.

+          Enable 'busybox --install [-s]' support.  This will allow you to use
+          busybox at runtime to create hard links or symlinks for all the
+          applets that are compiled into busybox.  This feature requires the

+          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

+        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.
