DESCRIPTION

       Follow the example above. Pretty straight forward. You create a client, assign a screen,
       add widgets, and then set the widgets.

   IO::LCDproc::Client
       It is the back engine of the module. It generates the connection to a ready listening
       server.

       METHODS

       new( name => 'Client_Name' [, host => $MYHOSTNAME] [, port => $MYPORTNUMBER] )
                   Constructor. Takes the following possible arguments (arguments must be given in key => value form):
                   host, port, and name. name is required.

       add( SCREENREF )
                   Adds the screens that will be attached to this client.

       connect()
                   Establishes connection to LCDproc server (LCDd).

       initialize()
                   Initializes client, screen and all the widgets  with the server.

       answer()
                   Reads an answer from the server

       flushAnswers()
                   Flushes all answers from the server (should be called regulary if you don't need the answers)
