/*
 *	Wad_list - list of open wads
 *
 *	The Wad_list class is designed to hold the list of open
 *	wads. It will probably have only one (global) instance.
 *	Here is how it's supposed to be used :
 *
 *	  extern Wad_list wl;
 *	  Wad_file *wf;
 *
 *	  // Is foo.wad in our list ?
 *	  for (wl.rewind (); wl.get (wf);)
 *	    if (strcmp (wf->filename, "foo.wad") == 0)
 *	    {
 *	      puts ("Got it !");
 *	      break;
 *	    }
 *
 *	  // Remove from the list all wads beginning with a "z"
 *	  for (wl.rewind (); wl.get (wf);)
 *	    if (*wf->filename == 'z')
 *	      wl.del ();
 */
