+/* NAME
+/*	domain_list 3
+/* SUMMARY
+/*	match a host or domain name against a pattern list
+/* SYNOPSIS
+/*	#include <domain_list.h>
+/*
+/*	DOMAIN_LIST *domain_list_init(pname, flags, pattern_list)
+/*	const char *pname;
+/*	int	flags;
+/*	const char *pattern_list;
+/*
+/*	int	domain_list_match(list, name)
+/*	DOMAIN_LIST *list;
+/*	const char *name;
+/*
+/*	void domain_list_free(list)
+/*	DOMAIN_LIST *list;
+/* DESCRIPTION
+/*	This is a convenience wrapper around the match_list module.
+/*
+/*	This module implements tests for list membership of a host or
+/*	domain name.
+/*
+/*	Patterns are separated by whitespace and/or commas. A pattern
+/*	is either a string, a file name (in which case the contents
+/*	of the file are substituted for the file name) or a type:name
+/*	lookup table specification.
+/*
+/*	A host name matches a domain list when its name appears in the
+/*	list of domain patterns, or when any of its parent domains appears
+/*	in the list of domain patterns. The matching process is case
+/*	insensitive. In order to reverse the result, precede a
+/*	pattern with an exclamation point (!).
+/*
+/*	domain_list_init() performs initializations. The pname
+/*	argument specifies error reporting context. The flags argument
+/*	is the bit-wise OR of zero or more of the following:
+/* .IP MATCH_FLAG_PARENT
+/*	The hostname pattern foo.com matches itself and any name below
+/*	the domain foo.com. If this flag is cleared, foo.com matches itself
+/*	only, and .foo.com matches any name below the domain foo.com.
+/* .IP MATCH_FLAG_RETURN
+/*	Request that domain_list_match() logs a warning and returns
+/*	zero, with list->error set to a non-zero dictionary error
+/*	code, instead of raising a fatal error.
+/* .PP
+/*	Specify MATCH_FLAG_NONE to request none of the above.
+/*	The last argument is a list of domain patterns, or the name of
+/*	a file containing domain patterns.
+/*
+/*	domain_list_match() matches the specified host or domain name
+/*	against the specified pattern list.
+/*
+/*	domain_list_free() releases storage allocated by domain_list_init().
+/* DIAGNOSTICS
+/*	Fatal error: unable to open or read a domain_list file; invalid
+/*	domain_list pattern.
+/* SEE ALSO
