[Mediawiki-l] Running several MediaWiki sites from the same PHP files

[Rotem Liss]

I'm running three MediaWiki sites, and I copy the PHP files from folder 
to folder. Can I run them somehow from the same PHP files, so I won't 
need to copy and update all the files three times? By the way, how do 
you do that in Wikimedia sites - copy the PHP files, or using the same 
ones? And how do you do that?

(Of course, using different LocalSettings.php for every site, and 
running from other folders.)
