FRIGN e51a2e6d2f Use ISO-date-format in manpages
The one specified by mdoc is hard to read for non-native
speakers from countries which read the date day-first (like
Germany, Greece, North-Korea, Swamp,...).
This is also consistent with how we generally specify dates
at suckless.org.

.Sh DESCRIPTION
.Nm
out bytes, characters or delimited fields from each line of
.Ar file
and write to stdout.
.Pp
If no
.Ar file
is given or
.Ar file
is '-',
.Nm
reads from stdin.
.Pp
.Ar list
is a comma or space separated list of numbers and ranges starting
from 1. Ranges have the form 'N-M'. If N or M is missing,
beginning or end of line is assumed. Numbers and ranges
may be repeated, overlapping and in any order.
.Pp
Selected input is written in the same order it is read
and is written exactly once.
.Sh OPTIONS
.Bl -tag -width Ds
.It Fl b Ar list | Fl c Ar list

.It Fl d Ar delim
Use
.Ar delim
as field delimiter, which can be an arbitrary string. Default is '\et'.
.It Fl f Ar list
.Ar list
specifies field numbers. Lines not containing field
delimiters are passed through, unless

is specified.
.It Fl n
Do not split multibyte characters. A character is written when its
last byte is selected.
.It Fl s

.Sh STANDARDS
The
.Nm
utility is compliant with the
.St -p1003.1-2013
specification.
.Pp
The possibility of separating numbers and ranges with a space and specifying
multibyte delimiters of arbitrary length is an extension to that specification.
