/*
 * This file is part of the load-balancing example
 *
 * In this example, a server process houses a single printer server object.
 * The server registers its printer server object with the naming service.
 * To demonstrate the load-balancing function of the naming service, this
 * example requires the launching of several server processes, each of which
 * houses a printer server object with a unique name.  Names have id and kind
 * components.  Unique names in this case refers to names with unique id values
 * but identical kind values.  This example uses stringified names that have
 * the format "<id>.<kind>".
