bool "less"
default y
help
'less' is a pager, meaning that it displays text files. It possesses
a wide array of features, and is an improvement over 'more'.

config BUSYBOX_CONFIG_FEATURE_LESS_ASK_TERMINAL
bool "Use 'tell me cursor position' ESC sequence to measure window"
default n
depends on BUSYBOX_CONFIG_FEATURE_LESS_WINCH
help
Makes less track window size changes.
If terminal size can't be retrieved and $LINES/$COLUMNS are not set,
this option makes less perform a last-ditch effort to find it:
position cursor to 999,999 and ask terminal to report real
cursor position using "ESC [ 6 n" escape sequence, then read stdin.
This is not clean but helps a lot on serial lines and such.
config BUSYBOX_CONFIG_FEATURE_LESS_DASHCMD
bool "Enable flag changes ('-' command)"

bool "Compress bbconfig data"
default n
depends on BUSYBOX_CONFIG_BBCONFIG
help
Store bbconfig data in compressed form, uncompress them on-the-fly
before output.
If you have a really tiny busybox with few applets enabled (and
bunzip2 isn't one of them), the overhead of the decompressor might
be noticeable. Also, if you run executables directly from ROM
and have very little memory, this might not be a win. Otherwise,
you probably want this.
config BUSYBOX_CONFIG_BEEP
bool "beep"
default n

When enabled expect strings which are started with a dash trigger
no-fail mode. That is when expectation is not met within timeout

scripts.
config BUSYBOX_CONFIG_FEATURE_CHAT_TTY_HIFI
bool "Force STDIN to be a TTY"

this on.
config BUSYBOX_CONFIG_FEATURE_CHAT_SEND_ESCAPES
bool "Support weird SEND escapes"
depends on BUSYBOX_CONFIG_CHAT
default n
help
Original chat uses some escape sequences in SEND arguments which
are not sent to device but rather performs special actions.
E.g. "\K" means to send a break sequence to device.
"\d" delays execution for a second, "\p" -- for a 1/100 of second.
Before turning this option on think twice: do you really need them?

Crond is a background daemon that parses individual crontab
files and executes commands on behalf of the users in question.

You should set it to true if you have devfs enabled.
The following keywords in devsfd.conf are supported:
"CLEAR_CONFIG", "INCLUDE", "OPTIONAL_INCLUDE", "RESTORE",

help
This is obsolete and should NOT be used anymore.
Use linux >= 2.6 (optionally with hotplug) and mdev instead!
For legacy systems -- if there is no way around devfsd -- this
tells busybox to look for names like /dev/loop/0 instead of
/dev/loop0. If your /dev directory has normal names instead of
devfs names, you don't want this.

'makedevs' is a utility used to create a batch of devices with
one command.
There are two choices for command line behaviour, the interface
as used by LEAF/Linux Router Project, or a device table file.
'leaf' is traditionally what busybox follows, it allows multiple
devices of a particluar type to be created per command.
e.g. /dev/hda[0-9]
Device properties are passed as command line arguments.
'table' reads device properties from a file or stdin, allowing
a batch of unrelated devices to be made with one command.
User/group names are allowed as an alternative to uid/gid.

Preload the files listed on the command line into RAM cache so that
subsequent reads on these files will not block on disk I/O.
This applet just calls the readahead(2) system call on each file.
It is mainly useful in system startup scripts to preload files
or executables before they are used. When used at the right time
(in particular when a CPU bound process is running) it can
significantly speed up system startup.
As readahead(2) blocks until each file has been read, it is best to
run this applet as a background job.
