You need this program only when you want to set up your own OGC server rather than use the public OGC server at ogc.gulpe.de:11111. You can get it from the CVS Repository.
To simplify the use of the OGC protocol in a Java application you
can use the OGC Java library. The package also contains a browser to
observe all games that are currently registered on the OGC server.

This is a tool to watch an OGC server. It displays a list of all games that run on that server. The list is being updated automatically. Download it from the Open Game Cache file list.
