    //   Since the SAM developers may look at this file as a template for their
    //   real GeneralFileTransfer service, it is perhaps better to do the work
    //   of making a copy into a designated area.
    // x We  merely strip the file:// from the URI; this adhoc class is not
    // beefed
    //   up to deal with genuine web access.
    // x An alternative would be to embed the last part of the file FQname into
    // the
    //   scratch file name, to try to maintain traceability in case things
    //   break.
