# Let's explain this RUN command:
#   1. First of all we refresh, since opensuse/ruby does a zypper clean -a in
#      the end.
#   2. Then we install dev. dependencies and the devel_basis pattern (used for
#      building stuff like nokogiri). With that we can run bundle install.
#   3. We then proceed to remove unneeded clutter: first we remove some packages
#      installed with the devel_basis pattern, and finally we zypper clean -a.
