 Other platforms
      The CD is written in vanilla ISO-9660 format. You have to mount it
       and open 'welcome.htm' with your favorite browser. All references
       are lower case with no version number. If your OS is case sensitive,
       mount the CD so that file names are lower case and version numbers 
       are ignored. All internal references are relative.
