/*
* @file ejs.h
* @brief Primary Embedded Javascript (ECMAScript) header.
* @overview This Embedded Javascript (EJS) header defines the
* public API. This API should only be used by those directly
* using EJS without using Embedded Server Pages (ESP). ESP
* wraps all relevant APIs to expose a single consistent API.
* \n\n
* This API requires the mpr/var.h facilities to create and
* manage objects and properties.
