+.Sh DESCRIPTION
+The
+.Nm
+utility provides minimal functionality to dump or display MCA records
+that were saved by the kernel during boot.
+The default behaviour of the
+.Nm
+utility is to display all new MCA records on stdout.
+When the
+.Fl d
+option is given, the records are dumped in binary form.
+The default file to which records are dumped is
+.Pa /var/log/mca.log .
+This can be changed by specifying the
+.Fl f
+option.
+New records are appended to the dump file.
+.Pp
+Previously dumped records can be displayed by giving the name of
+the dump file with the
+.Fl f
+option.
