Finally at the hardware level where a similar chaos exists (existed?),
there is the SCSI MMC (multimedia commands). This attempts to provide
a uniform command set for CD devices sort of like PostScript does for
printer commands. But in contrast to PostScript, there is no uniform
PostScript command language that programmers can write to. Instead
each OS has its own ``standard API.'' For example Adaptec's ASPI or
the Microsoft's DeviceIoControl on Microsoft Windows, or IOKit for
Apple's OS/X.
