[Pmwiki-users] how to use the cookbook file expirediff

[Gregory Watts]

Hello,

I'm a new user of pmwiki (http://www.greg-tools.com/pmwiki/).

I've found the expirediff.php file in the cookbook and I've placed the 
file in the scripts directory. But when I set the action to 'expirediff' 
in a url of a page it doesn't work? I tried local dir as well?
How to use this code? Should this new action be declared somewhere?

Best regards,

	Gregory
