getglobal tag method in 4.1 work 4

[Guy English <guy.english@...>]

Hi,
	
	Can someone please tell me how to do this:

	lua_settagmethod( lua, LUA_TNIL, "getglobal" );

	with the new meta table stuff.  The meta table section in the 
manual has yet to be written and in the compatibility code I found it 
mentions that "getglobal" is obsolete. I'd like to catch misses on 
global names so I can't pass off my own stuff.

Thanks for any help,
Guy
