/*
 * This program performs some simple processing on a device master-file,
 * mdevice (4) as specified in the "System File and Devices Reference
 * Manual" for Unix System V, Release 4.
 *
 * The first part of the program inhales the 'mdevice' file. Other processing
 * is dependent on the internal details of the character-device interface
 * used by Coherent - our aim is to supply details for a mapping layer that
 * converts the Coherent device system calling format.
