Understanding the basics of module building

So far, we have seen how useful modules are and the power that they can add to the framework. In order to master the framework, it is essential to understand building and working with modules. This will help us quickly extend the framework according to our needs. In the next few recipes, we will see how we can use Ruby scripting to build our own modules and import them into the framework.

How to do it...
