+Show verbose applets usage message
+CONFIG_FEATURE_VERBOSE_USAGE
+  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 automatic symlink creation for BusyBox built-in applets
+CONFIG_FEATURE_INSTALLER
+  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
+  /proc filesystem.
+
+Locale support
+CONFIG_LOCALE_SUPPORT
+  Enable this if your system has locale support, and you would like
+  busybox to support locale settings.
+
+Enable devfs support
+CONFIG_FEATURE_DEVFS
+  Enable if you want BusyBox to work with devfs.
+
+Clean up all memory before exiting
+CONFIG_FEATURE_CLEAN_UP
+  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.
+
+Buffers allocation policy
+CONFIG_FEATURE_BUFFERS_USE_MALLOC
+  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.

+  ar is an archival utility program used to create, modify, and
   extract contents from archives.  An archive is a single file holding
   a collection of other files in a structure that makes it possible to

-  original files' contents, mode (permissions), timestamp, owner, and
-  group are preserved in the archive, and can be restored on
-  extraction.  On an x86 system, the ar applet adds about XXX bytes.

   Unless you have a specific application which requires ar, you should
   probably say N here.
