/** @file bson_db.h

    This file contains the implementation of BSON-related methods that are required
    by the MongoDB database server.

    Normally, for standalone BSON usage, you do not want this file - it will tend to
    pull in some other files from the MongoDB project. Thus, bson.h (the main file
    one would use) does not include this file.
