This brings us to the end of our journey. We’ve come a long way from using OptionParser to parse the command line. We can now provide sophisticated help text, integrate with any other system or command, and distribute our code to any environment, all while keeping our app tested and maintainable. As we learned in this chapter, we can even spruce it up with sophisticated input and output, if the need should arise.

So, what’s left? The techniques we’ve learned are applicable to your everyday tasks and can be applied to any command-line app you need to write. We’ve also learned some handy tools and libraries; however, these only scratch the surface. The great thing about the Ruby community is the wide variety of tools available to solve ...
