Well, that's the *easy* solution ;-)  (which I didn't think of).

A serious question though. If I manually include stdconfig.php from
config.php, then this code will not have been executed before that:

	SDV($DefaultPage,"$DefaultGroup/$DefaultTitle");
	if ($pagename=='') $pagename=$DefaultPage;

I thought about this before, and it's bit like a chicken-and-hen problem

* $pagename is maybe needed by modules from config.php and stdconfig.php
* $DefaultPage is often defined in config.php
* default value of $pagename depends on $DefaultPage

One possible solution would be to use a function SetDefaultPage():

	function SetDefaultPage($group, $title) {
	  global $DefaultPage, $DefaultGroup, $DefaultTitle, $pagename;
	  $DefaultGroup=$group;
	  $DefaultTitle=$title;
	  $DefaultPage="$DefaultGroup/$DefaultTitle";
	  if (''==$pagename) $pagename=$DefaultPage;
        }

and you call this function from config.php when you wish to set the
default title and group. One advantage is that this will automatically
give $pagename a default value if that's necessary, and another advantage
is that we have consistency between $...Page, $...Title and $...Group
(assuming that's desirable of course).

That's the solution I'm using right now.
