The

The options are as follows:
.Bl -tag -width indent
Displays a help message.
.\"
.It Fl p
-Only display property
-.Fl p .
+Only display the specified
+.Ar property .
This can be can be specified multiple times and combined
with all other options.
.\"
.It Fl d
Only display devices with name
-.Fl d .
+.Ar device .
When used with
.Fl p ,
-only properties
