  33           This option makes top (and ps) ~20% faster (or 20% less CPU hungry),
  34           but code size is slightly bigger.

  37         bool "Support for /etc/networks"
  38         default n
  39         help
  40           Enable support for network names in /etc/networks. This is
  41           a rarely used feature which allows you to use names
  42           instead of IP/mask pairs in route command.

  45         bool "Command line editing"

  55         help
  56           Line editing code uses on-stack buffers for storage.
  57           You may want to decrease this parameter if your target machine
  58           benefits from smaller stack usage.

  64         help
  65           Enable additonal editing keys (Ctrl-E, Ctrl-U etc).
  66           Arrow keys, Home/End/Delete and Ctrl-W work even without this option.

  73           Enable vi-style line editing.  In shells, this mode can be
  74           turned on and off with "set -o vi" and "set +o vi".

 107         default y
 108         depends on BUSYBOX_CONFIG_FEATURE_EDITING
 109         help
 110           Setting this option allows for prompts to use things like \w and
 111           \$ and escape codes.

 117           Use clock_gettime(CLOCK_MONOTONIC) syscall for measuring
 118           time intervals (time, ping, traceroute etc need this).
 119           Probably requires Linux 2.6+. If not selected, gettimeofday
 120           will be used instead (which gives wrong results if date/time
 121           is reset).

 123 config BUSYBOX_CONFIG_IOCTL_HEX2STR_ERROR
 124         bool "Use ioctl names rather than hex values in error messages"
 125         default y
 126         help
 127           Use ioctl names rather than hex values in error messages
 128           (e.g. VT_DISALLOCATE rather than 0x5608). If disabled this
 129           saves about 1400 bytes.
