书籍摘录：
Rake is a very powerful tool that deserves its own chapter or even its own cookbook.There are a ton of useful recipes out there in the wild, so be sure to make the Rakefileone of your first stops in any new codebase you need to review. Understanding andusing Rake effectively is key to successfully managing any moderately complex Rubyproject, so be sure not to overlook its significance and practical utility.
If you want to make the most out of this tool, there are just a few things to keep in mind:Rake provides custom tasks for common needs such as generating RDoc, runningunit tests and packaging up a project for distribution. Because these tasks are highlyconfigurable, it is better to use them than to reinvent the wheel.
Any other repetitive action that is necessary for maintaining your project can bewrapped in a task to simplify things. Typically, any lengthy command that needsto be run in the shell is fair game for this sort of simplification.Any task that has a preceding desc（） call will be listed with a meaningful messagein the rake ——tasks output for your project.
Rake's ability to define prerequisite tasks allows you to build dependency-basedworkflows that allow you to model multiple-step tasks as needed.Namespaces can be used to segment off tasks into their own subspaces, minimizingthe risk of naming clashes.
I've tried to stick mainly to the easily overlooked aspects of Rake here, but there is awhole lot that we could have covered and didn't. Be sure to consult the Rake docu-mentation if you're interested in finding out more.
Depending on what you were looking for, this chapter may have been a bit differentfrom what you were expecting based on the title. However, what you will find is thatthe things we've discussed here will really take you far when it comes to improving themaintainability of your projects. Though far from glamorous, things like good docu-mentation, well-organized folders and files, and a way to automate as much of the gruntwork as possible does a whole lot for your projects.
Poorly maintained projects can be a huge drain on developer productivity and morale,yet nicely curated code can be downright enjoyable to work with, even if you're brand-new to a project. The tools and techniques we've discussed so far aren't going to makemaintenance completely painless, but will still provide a solid foundation to work offof that will grow over time.

原文赏析：
depsite the fact that I'm writing a book titled Ruby Best Practices, I freely admit that I write some dumb code sometimes
Most of the time when I need to use send() to call a private method in one of my tests, I try to rethink my interface.
Sometime it's a necessary evil, but most of the time it just means that things are looking to be refactored
