Each "vd" file contains the vendor dependent definitions that
the kernel must see.

Each "os" file contains the operating system dependent definitions
that the kernel must se.

Each "md" file contains the machine dependent definitions that
the kernel must see.

Each "cd" file includes a "vd" file, an "os" file and a "md" file, thereby
constructing a complete description of the machine offered 
by the vendor.
