According to
http://www.mediawiki.org/wiki/Manual:$wgScriptPath
the default value for $wgScriptPath is '/wiki'. Why isn't it
'dirname($_SERVER['SCRIPT_NAME'])'? I can then move the content in
my wiki around my website without having to update $wgScriptPath on
every move (?). Or am I missing something? I've set it in
LocalSettings.php and seems to work ok...
