Another great aspect of Libellus that is worth to mention is that Libellus is a greenware, which means you only need to copy the program and the Datenbank to your chosen folder and run it. No additional file is needed! So you can be sure you only put recognized files to your computer and say no to hidden files that you don't even know when it's being "injected" to your computer.
