* Pach from Erwan MAS <erwan@mas.nom.fr> that allows specification of the

version of a tgz file, for files that don't have a parseable version
     number. For consistency with --description, I made the otpino be called
     --version -- if no argument is specified to this option, it retains its
     old behavior of displaying alien's version, but it is now overloaded
     if given an argument. Closes: #165584
