请问如何配置Grinder
Set your CLASSPATH to include the grinder.jar file in the lib directory.

Start the console:
java net.grinder.Console

Create a grinder.properties file which defines the test you want to perform. See the examples directory for inspiration.

Start an agent process:
java net.grinder.Grinder
这些步骤到底如何操作拜托了?

Set your CLASSPATH to include the grinder.jar file in the lib directory.
在系统变量中设置classpath这个环境变量，其他的，我就不知道如何操作了。
