Extending Rails with Plug-ins

Abstract

Rails ships with a rich set of features and powerful functionality. It’s often said that Rails is designed to solve most problems most of the time. It can’t solve all problems or be all things to all people, and it doesn’t try to do that. Instead, it provides a mechanism to easily extend and augment the core functionality: plug-ins. Plug-ins give developers the freedom to write extensions to Rails without needing to include those additions in the Rails core code.
