/* NOTE: Standalone bson header for when not using MongoDB.
See also: bsondemo.
MongoDB includes ../db/jsobj.h instead. This file, however, pulls in much less code / dependencies.

bo and its helpers
"BSON" stands for "binary JSON" -- ie a binary way to represent objects that would be
represented in JSON (plus a few extensions useful for databases & other languages).
#pragma once
#error this header is for client programs, not the mongo database itself. include jsobj.h instead.
/* because we define simplistic assert helpers here that don't pull in a bunch of util -- so that
BSON can be used header only.
