the files that should go into the tar.gz file (in my case they are the
same as in the gem), and create a install.rb file for it. Or maybe I
should do it reversed, have a config.rb file, that is than required by
the gemspec file, and by the install.rb.
I just don't want to fool users, that don't have RubyGems installed, and
don't want to make packagers (FreeBSD ports etc.) the life more hard.
But at the same time, I don't want to duplicate the installer code (gem
