/* 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.

/* dict(3) generic dictionary manager
