    Title: "POP Email Port Spec"
    File:  %popspec.r
    Date:  10-Sep-1999
    Purpose: {
        POP port specification used to connect to an email
        server. All of the mail reading examples use this.
    }
    Note: {
        You can specify either a URL or a block containing
        the necessary information to open the POP port.
        The block approach is more general, as the username
        and password can be prompted for at run time.
