This is a simple command-line script that examines the local server status files to report on the status of a locally-running server, without incurring any network overhead nor using a worker.

scoreboard
Required - same as the "scoreboard" option in the middleware.
counter_file
Optional - same as the "counter_file" option in the middleware.
json
Optional - when provided, returns the data in JSON format. Defaults to false.
skip_ps_command
Optional - when provided, skip executes `ps command`. Please read perldoc Plack::Middleware::ServerStatus::Lite for details

This script mirrors the middleware's behaviour when the "skip_ps_command" option is set, because currently we do not know the server's parent pid (the process where the middleware was originally loaded, before worker processes are forked off). Therefore, data will be incomplete if not every worker has yet serviced a request before this script is run.
