+/*++
+/* NAME
+/*	postconf_unused 3
+/* SUMMARY
+/*	report unused parameters
+/* SYNOPSIS
+/*	#include <postconf.h>
+/*
+/*	void    pcf_flag_unused_main_parameters()
+/*
+/*	void    pcf_flag_unused_master_parameters()
+/* DESCRIPTION
+/*	These functions must be called after all parameter information
+/*	is initialized: built-ins, service-defined and user-defined.
+/*	In other words, don't call these functions with "postconf
+/*	-d" which ignores user-defined main.cf settings.
+/*
+/*	pcf_flag_unused_main_parameters() reports unused "name=value"
+/*	entries in main.cf.
+/*
+/*	pcf_flag_unused_master_parameters() reports unused "-o
+/*	name=value" entries in master.cf.
+/* DIAGNOSTICS
+/*	Problems are reported to the standard error stream.
+/* LICENSE
+/* .ad
+/* .fi
+/*	The Secure Mailer license must be distributed with this software.
