NAME
       ggzwrap - GGZ Gaming Zone game client wrapper

SYNOPSIS
       ggzwrap [OPTION...] --exec=GAME

DESCRIPTION
       This  wrapper  takes the place of a game client, and relays the control messages between the game and the invoking instance, which is a GGZ
       core client. One task is to manage different file descriptors than the ones which are normally used.  The GGZ clients do currently communi-
       cate using a socket which is passed in the environment variable GGZSOCKET, usually being fd 53 on the client side, so a call to:

       ggzwrap --fdin=$GGZSOCKET --fdout=$GGZSOCKET --exec=gameclient

       would  be equivalent to calling the client directly. However, there are games which communicate using the standard input/output facilities,
       so they need a redirection like:

       ggzwrap --fdin=0 --fdout=1 --exec=gameclient

       The GGZ game Muehle uses ggzwrap to demonstrate that game clients do not necessarily need to use any GGZ libraries. The downside is that  a
       lot  of	game client functionality will not be available.  Game clients which want to make use of the wrapper must add a command similar to
       the one above into the file ggz.modules.

OPTIONS
       --fdin=FD
	      File descriptor on which the game expects its input.

       --fdout=FD
	      File descriptor to which the game writes its output.

       --convert
	      This option automatically converts strings from network format to host format (more correctly, from libggz's easysock format to  the
	      normal null-terminated one) for the game server, and back in the other direction. This will be needed for most games.

       --exec=GAME
	      The game client to launch as a child process.

ENVIRONMENT VARIABLES
       GGZMODE
	      Set by a GGZ core client to tell games they're running in GGZ mode.

       GGZSOCKET
	      File descriptor for the connection to the invoking GGZ core client.
