	$file is passed from the calling php file.  index.php is by-hand
	set to


	and so on.  

	Because of my shoulder/typing woes, it was great that I got clued in
	above by Brad's thought that perhaos there were mis-matched "<?" 
	and "?>" tags.  A simply recursive grepping found out that it some 
	places I had "<?" <cr> instead of "<?php"> <cr>.   Adding the "php" 
	fixed everything.  

	Finally, you're right; this really, really is ancient php.
	Somthing i found pre-2004 and hacked until it worked.  The
	counter is missings lots of features, but I'll fix that pretty

	thanks to everybody ,
