它的一个特征是有一条修订语句，我是使用由修订控制系统扩展的关键字来定义该语句的。
It features a revision statement, which I define using a keyword to be expanded by the revision-control system.
语义同义词扩展机制仅限于扩展简单的关键字查询。
The semantic synonym expansion mechanism is limited to expand simple keyword queries.
比方说，一个关键字可以扩展成菜谱中的重量单位、硬件参考中的部件名称或者编程参考中的变量。
For example, a keyword can be extended as a unit of weight in a recipe, as a part name in a hardware reference, or as a variable in a programming reference.
