{
{    A configuration file must be installed for RHFAM/VE on each
{ local host that RHFAM/VE is executing on.  This configuration file
{ must define the following:
{
{    1)   The local host identification and the corresponding
{         attributes of the local host.  There must be one and only one
{         local host definition.
{
{    2)   The identification of all accessible remote hosts and
{         the logical identifiers that are used to request the services
{         provided by the corresponding host.  Each remote host must
{         be uniquely named.  The logical identifiers can apply to
{         multiple hosts.
{
{    3)   All NADs that are directly coupled to the local host
{         via a channel (local NADs).  There must be at least one local NAD
{         definition.
{
{    4)   All NADs that are directly accessible from the local NADs (remote
{         NADs).
{
{    5)   All physical paths between the local host and each remote host.
{         The user can either specify each of the desired paths or allow
{         the access method to generate the physical paths between the
{         above elements.
{
{    The configuration file consists of subcommand directives which
{ will be interpreted and installed by a MANAGE_RHFAM_NETWORK
{ subcommand (INSTALL_RHFAM_CONFIGURATION).  This file can be
{ created at any time using whatever editing procedures the user
{ is familiar with.
{
{    NOTE - The configuration directives do not provide for
{           individual status information to be returned.  The
{           status parameter on the INSRC or VERRC sub-commands is used
{           to convey the validity status for a set of configuration
{           directives.
{
{ The following terms are referenced in this section:
{
{ local host:  This refers to the mainframe where the configuration
{   file is being installed.
{
{ local NAD:  This refers to a NAD that is directly coupled, via a
{   channel, to the local host.
{
{ remote host:  This refers to a mainframe that can be accessed via
{   the LCN from the local host.
{
{ remote NAD:  This refers to a NAD that has an LCN communication
{   link between itself and a local NAD.  The remote NADs, in
{   conjunction with the local NADs, are used to define the physical
{   paths between the local host and the remote hosts.
{
{ loopback:  This refers to the establishment of a connection
{   where both connection end points are in a NAD which is attached to the
{   local host.  In this instance the local host and remote host refer to
{   the same host.
{
{      The following configuration directives are used to build the
{ RHFAM configuration file.  The only restriction on the order of
{ the directives is that elements, which are referenced within a directive,
{ must be previously defined by an appropriate directive.  (i.e. a remote
{ host directive must occur prior to a remote NAD directive that
{ specifies that remote host as a connecting host).
{
{    There are some additional constraints between the DEFINE_LCN_PATH
{ and AUTO_PATH_GENERATION directives.
