/**
 * Simple P4Java server factory usage demo. Does not require
 * any system properties to be set to run.<p>
 * 
 * This example prompts the user for a Perforce server
 * URI (in standard P4Java format), then uses the P4Java
 * ServerFactory class to retrieve a suitable IServer
 * interface onto the Perforce server identified by the URI.
 * The resulting IOptionsServer server interface is then queried
 * for the server's information in a minimalist version of
 * the "p4 info" command.<p>
 * 
 * Note the stacked exception / error handling: the use
 * of a separate RequestException catch clause is common
 * due to it being the only P4Java exception that contains
 * useful Perforce server-side generic and severity codes.
 * Note also that the app dies on the first exception instead
 * of trying to continue on...
