.Sh Chapter 3 - Utilities
Note that most (all?) of the utilities provided with NetBSD do not provide
internationalized diagnostic messages.  This is not a violation of the
.xopen
standards, as
.St -xbd5
does not require that any locale other than the
.Tn POSIX
locale be available, but it is an area where much improvement is possible.

.\" ---- admin ----
.Ss admin - create and administer SCCS files (DEVELOPMENT)
.notprovided admin
.Pp
.sccs admin
.
.Ss alias - define or display aliases
.compliant alias
.Pp
.builtin alias
.
.\" ---- ar ----
.Ss ar - create and maintain library archives
.Nx
uses the
.gnu
version of
.Nm ar ,
which is not compliant with
.St -xcu5 .
.Pp
In particular,
.gnu
.Nm ar
assumes that all
.Ar file
operands are object files.  In addition, the
.Fl r
and
.Fl q
flags are synonymous, and the
.Fl C
and
.Fl T
flags of
.xopen
.Nm ar
are not implemented.
.Pp
The
.Fl o , S ,
and
.Fl V
flags of
.gnu
.Nm ar
are compatible extensions to the
.xopen
specification.
.
.\" ---- asa ----
.Ss asa - interpret carriage-control characters
.compliant asa
.
.\" ---- at ----
.Ss at - execute commands at a later time
.notcompliant at
.Pp
In particular,
.Nx
.Nm at
does not implement the
.Fl t
flag of
.xopen
.Nm at ,
and the access control files of
.Nx at
are stored in
.Pa /var/at
rather than
.Pa /usr/lib/cron .
.Nx
.Nm at
also uses a different output format at job submission time and
when invoked with the
.Fl l
flag than that specified by
.St -xcu5 .
.Pp
In addition, the time grammar of
.Nx
.Nm at
is not completely compatible with that of
.xopen
.Nm at ,
including lack of support for timezone specifications.
As a compatible extension to the
.xopen
specification time grammar for
.Nm at ,
.Nx
.Nm at
allows the use of
.Li teatime ,
meaning 4:00 PM,
in place of
.Li noon
or
.Li midnight .
