New Ruby packaging guidelines draft

Hi everybody, As I promised, I drafted update to Ruby guidelines. You can see the changes here [1]. This is the summary: * Drop reference to EPEL5 * Use %setup macro to expand .gems since RPM 4.14 * Use %setup macro to expand the external test suite. * Drop the note, which recommends not shipping test suite, since we typically keep them despite this note * Updated test framework section to meet the current state. * Bundler and coverage frameworks usage discouraged. * Reference %gemspec_{add,remove}_dep macros. And although I promised, that this wont be breaking changes, there is one exception :/ The issue is with %gemspec_{add,remove}_dep macros, which currently expect the .gemspec file in the directory with the sources. However, the %setup macro generates the .gemspec file directly in %{_builddir} (i.e. one level above). I should probably update the macros to find the .gemspec there by default. This might break some packages (who is actually using the macros except me?), but it won't be worse then RubyGems freezing the strings in patch release, right? In other case, you would need always specify the path to the .gemspec ... So what do you think? Anything I missed or something I got wrong? Please let me know.
