    To use the Perforce proxy to access your Perforce server, set your P4PORT
    environment variable to "localhost:1666".

    To launch on startup:
    * if this is your first install:
        mkdir -p ~/Library/LaunchAgents
        cp #{plist_path} ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    * if this is an upgrade and you already have the #{plist_path.basename} loaded:
        launchctl unload -w ~/Library/LaunchAgents/#{plist_path.basename}
        cp #{plist_path} ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/#{plist_path.basename}

    Before starting the proxy server, you probably need to edit the plist to use
    the correct host and port for your Perforce server (replacing the default
    perforce:1666).
