Starts the DECwindows X proxy manager.

    The DECwindows proxy manager relieves proxy clients from
    managing proxy servers. Instead of sending a request directly
    to a proxy server, the client sends a request to the proxy
    manager indicating the requested X server. The proxy manager is
    responsible for either using an existing proxy server or starting
    a new proxy server. Once the manager finds a proxy server it
    returns the proxy server's address to the client. The proxy
    manager is an optional DECwindows component.

    If the proxy manager is used it is usually started automatically
    at DECwindows startup time.
