 .Sh DESCRIPTION
 .Nm Rtprio
 is used for controlling realtime process scheduling. 
-
+.Pp
 .Nm Idprio
 is used for controlling idletime process scheduling, and can be called
 with the same options as 
 .Nm Rtprio .
-
+.Pp
 A process with a realtime priority is not subject to priority
 degradation, and will only be preempted by another process of equal or
 higher realtime priority.
-
+.Pp
 A process with an idle priority will run only when no other
 process is runnable and then only if it's idle priority is equal or
 greater than all other runnable idle priority processes.
-
+.Pp
 .Nm Rtprio 
 or
 .Nm Idprio 
 when called without arguments will return the realtime priority
 of the current process.
-
+.Pp
 If
 .Nm rtprio
 is called with 1 argument, it will return the realtime priority
 of the process with the specified
 .Ar pid .
-
+.Pp
 If 
 .Ar priority
 is specified, the process or program is run at that realtime priority.
 If 
-.Ar -t
+.Fl t
 is specified, the process or program is run as a normal (non-realtime)
 process. 
-
+.Pp
 If
 .Ar -pid
 is specified, the process with the process identifier "pid" will be
 modified, else if
 .Ar command 
 is specified, that program is run with its arguments.
-
+.Pp
 .Ar Priority
 is an integer between 0 and RTP_PRIO_MAX (usually 31). 0 is the
 highest priority
-
+.Pp
 .Ar Pid
 of 0 means "the current process".
-
+.Pp
 Only root is allowed to set realtime priorities. Non-root processes may
 set idle priority levels for the current process only.
