+/* NAME
+/*	mail_conf_nbool 3
+/* SUMMARY
+/*	boolean-valued configuration parameter support
+/* SYNOPSIS
+/*	#include <mail_conf.h>
+/*
+/*	int	get_mail_conf_nbool(name, defval)
+/*	const char *name;
+/*	const char *defval;
+/*
+/*	int	get_mail_conf_nbool_fn(name, defval)
+/*	const char *name;
+/*	const char *(*defval)();
+/*
+/*	void	set_mail_conf_nbool(name, value)
+/*	const char *name;
+/*	const char *value;
+/*
+/*	void	get_mail_conf_nbool_table(table)

+/*
+/*	void	get_mail_conf_nbool_fn_table(table)
+/*	const CONFIG_NBOOL_TABLE *table;
+/* DESCRIPTION
+/*	This module implements configuration parameter support for
+/*	boolean values. The internal representation is zero (false)
+/*	and non-zero (true). The external representation is "no"
+/*	(false) and "yes" (true). The conversion from external
+/*	representation is case insensitive. Unlike mail_conf_bool(3)
+/*	the default is a string value which is subject to macro expansion.
+/*
+/*	get_mail_conf_nbool() looks up the named entry in the global
+/*	configuration dictionary. The specified default value is
+/*	returned when no value was found.
+/*
+/*	get_mail_conf_nbool_fn() is similar but specifies a function that
+/*	provides the default value. The function is called only
+/*	when the default value is needed.
+/*
+/*	set_mail_conf_nbool() updates the named entry in the global
+/*	configuration dictionary. This has no effect on values that
+/*	have been looked up earlier via the get_mail_conf_XXX() routines.
+/*
+/*	get_mail_conf_nbool_table() and get_mail_conf_int_fn_table() initialize
+/*	lists of variables, as directed by their table arguments. A table
+/*	must be terminated by a null entry.
+/* DIAGNOSTICS
+/*	Fatal errors: malformed boolean value.
