+/* NAME
+/*	string_list 3
+/* SUMMARY
+/*	match a string against a pattern list
+/* SYNOPSIS
+/*	#include <string_list.h>
+/*
+/*	STRING_LIST *string_list_init(pname, flags, pattern_list)
+/*	const char *pname;
+/*	int	flags;
+/*	const char *pattern_list;
+/*
+/*	int	string_list_match(list, name)
+/*	STRING_LIST *list;
+/*	const char *name;
+/*
+/*	void string_list_free(list)
+/*	STRING_LIST *list;
+/* DESCRIPTION
+/*	This is a convenience wrapper around the match_list module.
+/*
+/*	This module implements tests for list membership of a string.
+/*
+/*	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 string matches a string list when it appears in the list of
+/*	string patterns. The matching process is case insensitive.
+/*	In order to reverse the result, precede a pattern with an
+/*	exclamation point (!).
+/*
+/*	string_list_init() performs initializations. The pname
+/*	argument specifies error reporting context. The flags argument
+/*	is a bit-wise OR of zero or more of following:
+/* .IP MATCH_FLAG_RETURN
+/*	Request that string_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 specifies a list of string patterns.
+/*
+/*	string_list_match() matches the specified string against the
+/*	compiled pattern list.
+/*
+/*	string_list_free() releases storage allocated by string_list_init().
+/* DIAGNOSTICS
+/*	Fatal error: unable to open or read a pattern file or table.
+/* SEE ALSO
