.Sh NAME
.Nm ntpctl
.Nd control the Network Time Protocol daemon
.Sh SYNOPSIS
.Nm ntpctl
.Fl s Cm all | peers | Sensors | status
.Sh DESCRIPTION
The vertical bars are not escaped, and the scope of the
.Ic \&Cm
macro automatically resumes after them, without repeating the macro.
The keywords are ordered alphabetically.
.Pp
Note that there is a slight ambiguity:
When providing the
.Cm peers
keyword, the above synopsis line doesn't make it completely clear
that the
.Fl s
option is still required; that synopsis line could be misunderstood
in the sense that
.Nm Cm peers
were valid syntax and the
.Fl s
option only belonged to
.Cm all .
.Pp
The
.Xr mdoc 7
language doesn't allow to resolve such ambiguities in the SYNOPSIS;
doing so is the job of the DESCRIPTION section.
.Pp
It would be acceptable to provide a visual cue by suppressing spacing:
.Bd -filled
.Nm
.Fl s
.Cm all Ns | Ns Cm peers Ns | Ns Cm Sensors Ns | Ns Cm status
.Ed
.Pp
Or equivalently:
.Bd -filled
.Nm
.Fl s
.Sm off
.Cm all | peers | Sensors | status
.Sm on
.Ed
.Pp
However, in such a simple case, this is not required.
