-While each command has a handler which `System.CommandLine` will route to based on input, there is also a mechanism for short circuiting or altering the input before invoking you application logic. In between parsing and invocation, there is a chain of responsibility, which you can customize. A number of features of `System.CommandLine` make use of this. This is how the `--help` and `--version` options short circuit calls to your handler.

 Each call in the pipeline can take action based on the `ParseResult` and return early, or choose to call the next item in the pipeline. The `ParseResult` can even be replaced during this phase. The last call in the chain is the handler for the specified command.
