[Mediawiki-l] Multiple sites on one install

[jidanni at jidanni.org]

The ultimate minimalist solution consists of symlinks,
 aaaa.my.org -> mediawiki
 bbbb.my.org -> mediawiki
 cccc.my.org -> mediawiki
and in mediawiki/LocalSettings.php:
 $sites=array('aaaa','bbbb','cccc');
 foreach ($sites as $v){
  if(strpos($_SERVER['SCRIPT_FILENAME'].$_SERVER['PWD'],$v))
   {$wgDBname=$v;break;}}
 $wgLogo="/skins/common/images/$wgDBname.png"; $wgSitename=$wgDBname;
