+/*++
+/* NAME
+/*	postconf_main 3
+/* SUMMARY
+/*	basic support for main.cf
+/* SYNOPSIS
+/*	#include <postconf.h>
+/*
+/*	void	pcf_read_parameters()
+/*
+/*	void	pcf_show_parameters(fp, mode, param_class, names)
+/*	VSTREAM	*fp;
+/*	int	mode;
+/*	int	param_class;
+/*	char	**names;
+/* DESCRIPTION
+/*	pcf_read_parameters() reads parameters from main.cf.
+/*
+/*	pcf_set_parameters() takes an array of \fIname=value\fR
+/*	pairs and overrides settings read with pcf_read_parameters().
+/*
+/*	pcf_show_parameters() writes main.cf parameters to the
+/*	specified output stream.
+/*
+/*	Arguments:
+/* .IP fp
+/*	Output stream.
+/* .IP mode
+/*	Bit-wise OR of zero or more of the following:
+/* .RS
+/* .IP PCF_FOLD_LINE
+/*	Fold long lines.
+/* .IP PCF_SHOW_DEFS
+/*	Output default parameter values.
+/* .IP PCF_SHOW_NONDEF
+/*	Output explicit settings only.
+/* .IP PCF_HIDE_NAME
+/*	Output parameter values without the "name =" prefix.
+/* .IP PCF_SHOW_EVAL
+/*	Expand $name in parameter values.
+/* .RE
+/* .IP param_class
+/*	Bit-wise OR of one or more of the following:
+/* .RS
+/* .IP PCF_PARAM_FLAG_BUILTIN
+/*	Show built-in parameters.
+/* .IP PCF_PARAM_FLAG_SERVICE
+/*	Show service-defined parameters.
+/* .IP PCF_PARAM_FLAG_USER
+/*	Show user-defined parameters.
+/* .RE
+/* .IP names
+/*	List of zero or more parameter names. If the list is empty,
+/*	output all parameters.
+/* DIAGNOSTICS
+/*	Problems are reported to the standard error stream.
