+/*++
+/* NAME
+/*	postconf_misc 3
+/* SUMMARY
+/*	miscellaneous low-level code
+/* SYNOPSIS
+/*	#include <postconf.h>
+/*
+/*	void	pcf_set_config_dir()
+/*
+/*	const char *pcf_get_main_path()
+/*
+/*	const char *pcf_get_master_path()
+/* DESCRIPTION
+/*	pcf_set_config_dir() forcibly overrides the var_config_dir
+/*	parameter setting with the value from the environment or
+/*	with the default pathname, and updates the mail parameter
+/*	dictionary.
+/*
+/*	pcf_get_main_path() and pcf_get_master_path() return a
+/*	pointer to a cached main.cf or master.cf full pathname,
+/*	based on the current var_config_dir setting. The functions
+/*	call pcf_set_config_dir() when no full pathname is cached.
+/* DIAGNOSTICS
+/*	Problems are reported to the standard error stream.
+/* LICENSE
+/* .ad
+/* .fi
+/*	The Secure Mailer license must be distributed with this software.
