+.Bl -tag -width ".Fl d Ar directives"
+.It Fl ?\& | h
+Print help.
+.It Fl c Ar file
+Use an alternative configuration
+.Ar file .
+.It Fl g Ar directives
+Set global configuration directives.
+See
+.Sx EXAMPLES
+for details.
+.It Fl p Ar prefix
+Set prefix path.
+Default value is
+.Pa %%PREFIX%% .
+.It Fl q

+.It Fl s Ar signal
+Send signal to the master process.
+The argument
+.Ar signal
+can be one of:

+Print
+.Nm
+version.
+.It Fl V
+Print
+.Nm
+version, compiler version and
+.Pa configure
+script parameters.
+.El
+.Sh SIGNALS
+The master process of
+.Nm
+can handle the following signals.
+.Pp
+.Bl -tag -width ".It Dv SIGINT , SIGTERM" -compact
+.It Dv SIGINT , SIGTERM
+Shut down quickly.
+.It Dv SIGHUP
+Reload configuration, start the new worker process with a new
