/**
 * A local version command.

 * available Version class if server is not running or if the version could not
 * be obtained from a server for some reason. The idea is to get the version
 * of server software, the server process need not be running. This command
 * does not return the version of local server installation if its
 * options (host, port, user, passwordfile) identify a running server.
