+=head1 SYNOPSIS
+
+    use FML::Process::Addr;

+    $curproc->run();
+
+=head1 DESCRIPTION
+
+FML::Process::Addr provides the main function for C<fmladdr>.
+
+See C<FML::Process::Flow> for the flow detail.

+constructor.
+It make a C<FML::Process::Kernel> object and return it.

+
+the top level dispatcher for C<fmlconf> and C<fmladdr>.
+
+It kicks off internal function
+C<_fmlconf($args)> for C<fmlconf>

+
+NOTE:
+C<$args> is passed from parrent libexec/loader.

+=head2 C<_fmladdr($args)> (INTERNAL USE)
+
+switch of C<fmladdr> command.
+It kicks off <FML::Command::$command> corrsponding with
+C<@$argv> ( $argv = $args->{ ARGV } ).
+
+C<Caution:>
+C<$args> is passed from parrent libexec/loader.
+We construct a new struct C<$command_args> here to pass parameters
+to child objects.
+C<FML::Command::$command> object takes them as arguments not pure
+C<$args>. It is a little mess. Pay attention.
+
+See <FML::Process::Switch()> on C<$args> for more details.
