I would like to keep our version updated to 1.7 all the time; but we have lots of extensions installed and other things in the same directory as mediawiki. If I run svn up on my local directory, would it only upgrade the mediawiki files that have changed, without removing our special stuff? And no, I haven't changed any actual mediawiki files other than LocalSettings.php; so would this work?
(P.S. I hope this gets to the list, there may be a duplicate copy as I'm not quite sure I'm doing this right) w/
