.Sh NAME
.Nm setopt
.Nd parse command options
.
.Sh SYNOPSIS
.Nm
.Ar optstring
.Op Ar args ...
.
.Sh DESCRIPTION
.Nm
behaves similarly to
.Xr getopt 1 ,
except that it produces quoted output
appropriate for use with the
.Nm eval
shell builtin.
This allows arguments containing whitespace
to survive parsing.

.Sh EXAMPLES
.Bd -literal -offset indent
args=$(setopt abo: "$@")
eval set -- "$args"

.Sh SEE ALSO
.Xr getopt 1 ,
.Xr sh 1 ,
.Xr getopt 3
.
.Sh HISTORY
The
.Xr getopt 1
manual page of
.Fx
reads,
.Do
Arguments containing white space
or embedded shell metacharacters
generally will not survive intact;
this looks easy to fix but isn't.
.Dc
Yet here we are.
