TODO:
* Check if the archive already exists
  * if 'bin-package.version' exists, we are in a binary archive,
      execute all commands.
  * otherwise, check if a binary archive exists.
     If no, create an empty
       `bin-package.version` file to force execution of all commands.
     If yes, create a directory package.cached/ containing that archive,
       bin-package.version and bin-package.config.
     In wrap-install, perform the installation of the archive.
