          it out ala::

              //    'minor': 0, 
              //    'version': 124

            },
            ...
          
          b. if you *do* support a format, name your files
          according to the value in this mapping, e.g.: if
          you're supporting quicktime 6, export files with
          a .mov extension.  See URL_FORMAT below for more
          on naming files.
        
        N.b.: you can remove whole items (e.g.: remove quicktime)
        and you can edit the values (e.g.: '.mp4') but *do not*
        edit the keys (e.g.: '7andabove') as that will break the
        detection logic!
        
        Also, rather obviously, the 'ext' must be unique if the
        file it references is unique.
