并不是不能为命令式程序进行那种程序证明，而是状态改变发生的次数之多使得那些证明不具意义。
It's not that program proofs cannot be done with imperative programs, but that the number of state changes that occur make them unwieldy.
扩展命令提供程序类似于任务命令提供程序，不同之处是扩展命令提供程序只需提供创建和加载步骤的方法。
An extension command provider is similar to a task command provider, except that the extension command provider only needs to provide methods to create and load steps.
这是因为扩展命令提供程序是指通过添加其他步骤扩展基本命令。
This is because the extension command provider is meant to extend a base command by adding additional steps.
通过创建JAR文件并将其放置在类路径中，便从本质上完成了包装命令提供程序、命令和命令定义文件。
