21.7. Conclusion
We’ve seen several tools in this chapter that make life easier for the Ruby developer. Common tools are the interactive Ruby tool irb, the RubyGems installer, and the ri documentation tool. We’ve looked at editor add-ons for Ruby. Finally we’ve looked briefly at some IDEs that support Ruby. But the most important tool of all is not a piece of software. It is “peopleware”—the Ruby community itself. That is the topic of our next (and final) chapter.
