  19           Enable options and features which are not essential.
  20           Select this only if you plan to use busybox on full-blown
  21           desktop machine with common Linux distro, not on an embedded box.

  26         help
  27           This option makes grep, sed etc handle rare corner cases
  28           (embedded NUL bytes and such). This makes code bigger and uses
  29           some GNU extensions in libc. You probably only need this option
  30           if you plan to run busybox on desktop.

  36           This option will enable backwards compatibility with SuSv2,
  37           specifically, old-style numeric options ('command -1 <file>')
  38           will be supported in head, tail, and fold. (Note: should
  39           affect renice too.)

  45           Use this option if you are trying to compile busybox with
  46           compiler other than gcc.
  47           If you do use gcc, this option may needlessly increase code size.

  51         default BUSYBOX_CONFIG_FEATURE_BUFFERS_GO_ON_STACK
  52         help
  53           There are 3 ways BusyBox can handle buffer allocations:
  54           - Use malloc. This costs code size for the call to xmalloc.
  55           - Put them on stack. For some very small machines with limited stack
  56             space, this can be deadly. For most folks, this works just fine.
  57           - Put them in BSS. This works beautifully for computers with a real
  58             MMU (and OS support), but wastes runtime RAM for uCLinux. This
  59             behavior was the only one available for BusyBox versions 0.48 and
  60             earlier.

  77           All BusyBox applets will show help messages when invoked with
  78           wrong arguments. You can turn off printing these terse usage
  79           messages if you say no here.
  80           This will save you up to 7k.

  87           All BusyBox applets will show more verbose help messages when
  88           busybox is invoked with --help. This will add a lot of text to the
  89           busybox binary. In the default configuration, this will add about
  90           13k, but it can add much more depending on your configuration.

  98           when <applet> --help is called.
  99
 100           If you have a really tiny busybox with few applets enabled (and
 101           bunzip2 isn't one of them), the overhead of the decompressor might
 102           be noticeable. Also, if you run executables directly from ROM
 103           and have very little memory, this might not be a win. Otherwise,
 104           you probably want this.

 111           busybox at runtime to create hard links or symlinks for all the
 112           applets that are compiled into busybox.

 125           This makes various applets aware that one byte is not
 126           one character on screen.
 127
 128           Busybox aims to eventually work correctly with Unicode displays.
 129           Any older encodings are not guaranteed to work.
 130           Probably by the time when busybox will be fully Unicode-clean,
 131           other encodings will be mainly of historic interest.

 165           Any character with Unicode value bigger than this is assumed
 166           to be non-printable on output device. Many applets replace
 167           such chars with substitution character.
 168
 169           The idea is that many valid printable Unicode chars are
 170           nevertheless are not displayed correctly. Think about
 171           combining charachers, double-wide hieroglyphs, obscure
 172           characters in dozens of ancient scripts...
 173           Many terminals, terminal emulators, xterms etc will fail
 174           to handle them correctly. Choose the smallest value
 175           which suits your needs.
 176
 177           Typical values are:
 178           126 - ASCII only
 179           767 (0x2ff) - there are no combining chars in [0..767] range
 180                         (the range includes Latin 1, Latin Ext. A and B),
 181                         code is ~700 bytes smaller for this case.
 182           4351 (0x10ff) - there are no double-wide chars in [0..4351] range,
 183                         code is ~300 bytes smaller for this case.
 184           12799 (0x31ff) - nearly all non-ideographic characters are
 185                         available in [0..12799] range, including
 186                         East Asian scripts like katakana, hiragana, hangul,
 187                         bopomofo...
 188           0 - off, any valid printable Unicode character will be printed.

 257           As a size optimization, busybox normally exits without explicitly
 258           freeing dynamically allocated memory or closing files. This saves
 259           space since the OS will clean up for us, but it can confuse debuggers
 260           like valgrind, which report tons of memory and resource leaks.
 261

 375           This is an experimental option which directs applets about to
 376           call 'exec' to try and find an applicable busybox applet before
 377           searching the PATH. This is typically done by exec'ing
 378           /proc/self/exe.
 379           This may affect shell, find -exec, xargs and similar applets.
 380           They will use applets even if /bin/<applet> -> busybox link
 381           is missing (or is not a link to busybox). However, this causes
 382           problems in chroot jails without mounted /proc and with ps/top
 383           (command name can be shown as 'exe' for applets started this way).
