The code under Compress/Rar* is licensed under a specific unRAR license Also Compress/LzfseDecoder.cpp is covered by BSD3 The unRAR code is removed from the source drv since the license posits you agree or remove the code from your hard drive This adds some complexity to updating p7zip so there is also an update script Meta has been updated and tweaked
