+/*++
+/* 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.
