=head1 DIAGNOSTICS

B<spd> is usually invoked indirectly, via spshed(8) from system
startup procedures or other programs such as gspl-start(1).

Thereafter it runs as a "daemon process" and diagnostics are not
written to any terminal but to the file F<spshed_reps>.

In the event of any problems this file should be examined.
