                      3:  *      Definitions used in the font file.  This is the file which holds
                      4:  *      information about cartridge and download fonts.  The file format
                      5:  *      is quite basic:  a header for verification; then an array of
                      6:  *      records,  each with a header.  These records contain FONTMAP
                      7:  *      information.  Cartridges have an array of these, one for each
                      8:  *      font.  Finally,  the tail of the file contains extra data, as
                      9:  *      required.  For download fonts,  this would be the download data.
