       JMX::Jmx4Perl::J4psh::CommandHandler - Handler for j4psh	commands

       This object is responsible for managing JMX::Jmx4Perl::Command objects
       which are at the	heart of j4psh and provide all features. During
       startup it registeres commands dynamically and pushes the
       JMX::Jmx4Perl::Shell context to them for	allowing to access the agent
       and other handlers.

       Registration is occurs in two phases:


       It also keeps a stack of	so called navigational context which can be
       used to provide a menu like structure (think of it like directories
       which can be entered). If the stack contains elements, the navigational
       commands	".." and "/" are added to traverse the stack. "/" will always
       jump to the top of the stack (the root directory) whereas ".." will pop
       up one level in the stack (the parent directory). Commands which	want
       to manipulate the stack like pushing themselves on the stack should use
       the methods "push_on_stack" or "reset_stack" (for jumping to the	top of
       the menu).

       $command_handler	= new
	   Create a new	command	handler	object.	The arguments to be passed are
	   the context object ($context) and the shell object ($shell) in
	   order to update the shell's current command set.

	   Update the stack with an entry of name $context which provides the
	   commands $cmds. $cmds must be a hashref as known to Term::ShellUI,
	   whose "commands" method is used to update the shell.	Additionally
	   it updates the shell's prompt to reflect the	state of the stack.

	   Reset the stack and install the top and global commands as
	   collected from the registered OSGi::Osgish::Command.

       $command	= $command_handler->command($command_name)
	   Get a registered command by name
