This is a fork of the 2.4.x branch of SilverStripe Framework used by the OPAC software DiscoveryNG.
The main change is the possibility to change the "ASSETS_DIR" constant, in order to be able to move the
assets and silverstripe-cache folder wherever you want.
In DNG this is used to allow a multi-site installation of the software. The assets folder path is computed at runtime watching the incoming request URI.
