+/* NAME
+/*	dict_inline 3
+/* SUMMARY
+/*	dictionary manager interface for inline table
+/* SYNOPSIS
+/*	#include <dict_inline.h>
+/*
+/*	DICT	*dict_inline_open(name, open_flags, dict_flags)
+/*	const char *name;
+/*	int	open_flags;
+/*	int	dict_flags;
+/* DESCRIPTION
+/*	dict_inline_open() opens a read-only, in-memory table.
+/*	Example: "\fBinline:{\fIkey_1=value_1, ..., key_n=value_n\fR}".
+/*	The longer form with { key = value } allows values that
+/*	contain whitespace or comma.
+/* SEE ALSO
+/*	dict(3) generic dictionary manager
+/* LICENSE
