construct/include/ircd/db/database/README.md

This directory contains lower-level interfaces which generally require including RocksDB for symbols which cannot be forward declared. These are used internally by ircd/db.cc and are not necessary for developers wishing to use ircd::db. The public interfaces to ircd::db are one directory up.

The only essential public interface here in the standard include stack is database.h itself. Also note that ircd::db::database is typedef'ed to ircd::database.
