/* Structure used to store settings for specific drives in knowndrives[]. The
 * elements are used in the following ways:
 *
 *  modelfamily     Informal string about the model family/series of a 
 *                  device. Set to NULL if no info (apart from device id)
 *                  known.
 *  modelregexp     POSIX regular expression to match the model of a device.
 *                  This should never be NULL (except to terminate the
 *                  knowndrives array).
 *  firmwareregexp  POSIX regular expression to match a devices's firmware
 *                  version.  This is optional and should be NULL if it is not
 *                  to be used.  If it is non-NULL then it will be used to
 *                  narrow the set of devices matched by modelregexp.
 *  warningmsg      A message that may be displayed for matching drives.  For
 *                  example, to inform the user that they may need to apply a
 *                  firmware patch.
 *  vendoropts      Pointer to first element of an array of vendor-specific
 *                  option attribute/value pairs that should be set for a
 *                  matching device unless the user has requested otherwise.
 *                  The user's own settings override these.  The array should
 *                  be terminated with the entry {0,0}.
 *  specialpurpose  Pointer to a function that defines some additional action
 *                  that may be taken for matching devices.
 *  functiondesc    A description of the effect of the specialpurpose
 *                  function.  Used by showpresets() and showallpresets() to
 *                  make the output more informative.
