The command-line client for the Gateway can be obtained from our SourceForge project page here . The source is available along with a simple .exe and .jar file for convenience. The installation in Linux or Windows is fairly straightforward as documented below.
The client for Windows is supplied as part of an installer that places it in the Start menu and adds appropriate entries into Add/Remove programs.
No installation is needed to run the client, it can be executed from a .jar file.
