Details edit

Filesystem extensions directory. Defaults to $IP /../extensions.

To compile extensions with HipHop, set $wgExtensionsDirectory correctly. To include the extension setup file from LocalSettings.php, use code like:

require( MWInit::extensionSetupPath( 'Extension/Extension.php' ) );

It is not necessary to set this variable unless you use MWInit::extensionSetupPath().
